OP470GPZ Equivalent & Substitute Parts

Part Overview

The OP470GPZ is a general-purpose operational amplifier manufactured by Analog Devices Inc., configured as a quad (4-circuit) integrated circuit in a 14-DIP through-hole package. This device is actively produced and widely used in analog signal processing applications requiring moderate bandwidth and low input bias current characteristics. The OP470GPZ operates across a wide supply voltage range of 9V to 36V and maintains performance across the industrial temperature range of -40°C to 85°C.

Substitute parts become necessary when the OP470GPZ reaches end-of-life status, when inventory constraints occur, or when application requirements demand enhanced performance characteristics such as higher slew rate, lower input offset voltage, or rail-to-rail output capability. The substitute parts listed below maintain functional compatibility through equivalent circuit count, identical packaging, and overlapping electrical specifications.

Substitute Part Grouping Explanation

Substitution compatibility for the OP470GPZ is determined by strict adherence to the following mandatory parameters:

Mandatory Compatibility Parameters:

Number of Circuits: Must equal 4
Package / Case: Must be 14-DIP (0.300", 7.62mm)
Mounting Type: Must be Through Hole
Voltage Supply Range: Application supply voltage must fall within the substitute part's minimum and maximum supply voltage specifications

Performance Enhancement Parameters: Substitute parts may offer improved performance in the following areas while maintaining mandatory compatibility:

Slew Rate: Higher values enable faster signal transitions
Gain Bandwidth Product: Higher values extend frequency response
Current - Input Bias: Lower values reduce input loading effects
Voltage - Input Offset: Lower values improve DC accuracy
Current - Supply: Lower values reduce power consumption

Temperature Range Consideration: The OP470GPZ operates from -40°C to 85°C. Substitute parts with narrower temperature ranges (such as 0°C to 70°C) are functionally compatible but may not be suitable for applications requiring the full industrial temperature range.

Amplifier Type Variants: Substitute parts are available in two amplifier type categories: General Purpose and J-FET. General Purpose amplifiers maintain similar input bias current and offset voltage characteristics. J-FET amplifiers offer significantly lower input bias current (measured in picoamperes rather than nanoamperes) at the cost of higher input offset voltage and different slew rate characteristics.

Engineering Selection Recommendations

For Direct Replacement with Active Product Status:

The OPA4227PA and TLE2144 series (TLE2144CN, TLE2144AIN) are the only substitute parts with Active product status. The OPA4227PA offers superior DC accuracy with 10 µV input offset voltage and exceptional input bias current of 2.5 nA, making it suitable for precision analog applications. The TLE2144 series provides rail-to-rail output capability and significantly higher slew rate (45 V/µs), beneficial for high-speed signal processing applications.

For Extended Temperature Range Applications:

Applications requiring operation across the full -40°C to 85°C range are compatible with OP470GPZ, NJM2058D, TL3474AIN, OPA4131PJ, and OPA4227PA. The TL3474AIN extends the upper temperature limit to 105°C, providing additional thermal margin for high-temperature environments.

For Low-Power Applications:

The OPA4227PA (3.7 mA total supply current) and OPA4131PJ (1.5 mA total supply current) offer significant power consumption reduction compared to the OP470GPZ (9 mA). The LT1058CN#PBF provides the lowest supply current at 1.7 mA, though its minimum supply voltage requirement of 20V restricts applicability to higher voltage systems.

For High-Speed Signal Processing:

Applications requiring slew rates exceeding 3 V/µs benefit from TL3474 series (13 V/µs), TLE2144 series (45 V/µs), LT1058CN#PBF (13 V/µs), or OPA4131PJ (10 V/µs). The TLE2144 series provides the highest slew rate performance.

For Precision DC Applications:

The OPA4227PA delivers the lowest input offset voltage (10 µV) and input bias current (2.5 nA), making it optimal for precision instrumentation and measurement applications where DC accuracy is critical.

Compliance and Regulatory Considerations:

All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, consistent with the OP470GPZ. All parts carry EAR99 export classification and identical HTSUS commodity codes, ensuring regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the OP470GPZ with any 4-circuit operational amplifier in a 14-DIP package?

A: No. Substitution requires matching the 14-DIP through-hole package format and 4-circuit configuration, but the substitute part's supply voltage range must encompass the application's operating voltage. Additionally, the substitute part's operating temperature range must cover the application's temperature requirements. Performance parameters such as slew rate, gain bandwidth product, and input offset voltage may differ between parts.

Q: What is the primary difference between General Purpose and J-FET amplifier types in this list?

A: General Purpose amplifiers (such as OP470GPZ, OPA4227PA, TL3474, TLE2144) use bipolar input stages and typically exhibit input bias currents in the nanoampere range. J-FET amplifiers (LT1058CN#PBF, OPA4131PJ) use field-effect transistor input stages and exhibit input bias currents in the picoampere range, approximately 1000 times lower. This makes J-FET amplifiers superior for high-impedance input applications but they generally have higher input offset voltages.

Q: The OP470GPZ operates from 9V to 36V. Can I use a substitute part with a 4V minimum supply voltage in a 9V to 36V application?

A: Yes. A substitute part with a 4V minimum supply voltage is compatible with a 9V to 36V application because the application's 9V minimum exceeds the part's 4V minimum requirement. The substitute part's maximum supply voltage must also be equal to or greater than the application's 36V maximum.

Q: Why do some substitute parts show "Last Time Buy" status?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for that part number. Existing inventory may still be available, but no new production will occur after a specified date. For long-term designs, Active status parts such as OPA4227PA or TLE2144 series are preferred.

Q: What does "Rail-to-Rail" output capability mean for the TLE2144 series?

A: Rail-to-rail output means the operational amplifier can swing its output voltage to within a small margin of both the positive and negative supply rails. This maximizes the usable output voltage range compared to conventional amplifiers that cannot reach the supply rails. This feature is beneficial in low-voltage applications or when maximum output swing is required.

Q: The LT1058CN#PBF has a 20V minimum supply voltage, but the OP470GPZ minimum is 9V. Why is this listed as a substitute?

A: The LT1058CN#PBF is listed as a substitute for applications that operate at 20V or higher supply voltages. It is not a universal substitute for all OP470GPZ applications. Selection must verify that the application's minimum supply voltage meets or exceeds 20V.

Q: How do I determine if a substitute part will work in my application?

A: Verify the following mandatory parameters: (1) The substitute part must be a 4-circuit operational amplifier in a 14-DIP through-hole package; (2) The application's supply voltage range must fall completely within the substitute part's minimum and maximum supply voltage specifications; (3) The application's operating temperature range must fall completely within the substitute part's temperature range. After confirming these mandatory parameters, evaluate performance parameters such as slew rate, gain bandwidth product, and input offset voltage to ensure they meet application requirements.

Q: Are all these substitute parts RoHS compliant?

A: All substitute parts listed maintain RoHS3 compliance status, consistent with the OP470GPZ. All parts are also REACH unaffected, ensuring regulatory compatibility for applications subject to these environmental and chemical restriction requirements.

Q: What is the significance of the different input offset voltage values among these parts?

A: Input offset voltage represents the DC voltage difference between the two input terminals when the output is at zero. Lower input offset voltage values (such as OPA4227PA at 10 µV) are critical for precision DC applications where small signal errors cannot be tolerated. Higher input offset voltage values (such as TL3474 at 1000 µV) are acceptable for AC-coupled applications or when offset trimming is available in the circuit design.
