OP470GP Equivalent & Substitute Parts

Part Overview

The OP470GP is a general-purpose operational amplifier integrated circuit manufactured by Analog Devices Inc., configured as a quad amplifier (4 circuits) in a 14-DIP through-hole package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. The OP470GP operates across a wide supply voltage range (9V to 36V) and temperature range (-40°C to 85°C), making it suitable for general-purpose analog signal processing applications. Due to its obsolete status, direct replacements and functionally equivalent alternatives are required for new designs and legacy system maintenance.

Substitute Part Grouping Explanation

Substitution of the OP470GP is determined by the following critical parameters: amplifier type (general purpose), number of circuits (4), package configuration (14-DIP through-hole), and electrical operating ranges (supply voltage 9V to 36V, temperature -40°C to 85°C). Substitute parts are grouped into two categories:

Direct Equivalents: Parts that maintain identical or superior electrical characteristics within the same package footprint and amplifier classification. The OP470GPZ represents a direct equivalent with active product status and identical electrical specifications.

Functional Alternatives: Parts that satisfy the core application requirements (quad general-purpose amplifier in 14-DIP package) but may exhibit different electrical performance characteristics such as slew rate, gain bandwidth product, input bias current, or supply current. These alternatives are suitable when the specific electrical performance of the OP470GP is not a critical design constraint.

Technology Variants: J-FET amplifier designs (LT1058CN#PBF, OPA4131PJ) and rail-to-rail output amplifiers (TLE2144ACN, TLE2144AIN) that provide enhanced performance in specific parameters but require design verification for compatibility.

Engineering Selection Recommendations

Primary Recommendation: OP470GPZ

The OP470GPZ is the direct equivalent replacement for the OP470GP. This part maintains identical electrical specifications across all critical parameters: 3V/µs slew rate, 6MHz gain bandwidth product, 15nA input bias current, 400µV input offset voltage, and 9V to 36V supply range. The OP470GPZ is manufactured by Analog Devices Inc. with active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. The only difference is packaging format (tube versus unspecified for the original), which does not affect electrical performance or pin compatibility.

Secondary Recommendation: OPA4227PA

The OPA4227PA is suitable for applications where lower input bias current (2.5nA versus 15nA) and lower input offset voltage (10µV versus 400µV) provide performance advantages. This part is manufactured by Burr Brown and maintains the same supply voltage range and temperature operating range as the OP470GP. The OPA4227PA exhibits lower supply current (3.7mA versus 9mA), which is beneficial for power-constrained applications. This part is active and suitable for new designs requiring enhanced precision.

Tertiary Recommendation: NJM2060D#

The NJM2060D# is an active product from Nisshinbo Micro Devices that provides general-purpose amplification in the same 14-DIP package. This part exhibits higher slew rate (4V/µs versus 3V/µs) and higher gain bandwidth product (10MHz versus 6MHz), making it suitable for applications requiring faster signal processing. The operating temperature range is narrower (-20°C to 75°C versus -40°C to 85°C), which must be verified against application requirements.

Alternative for Low-Power Applications: LT1058CN#PBF

The LT1058CN#PBF is a J-FET amplifier design with significantly lower input bias current (7pA versus 15nA) and lower supply current (1.7mA versus 9mA). This part is active and ROHS3 compliant. The minimum supply voltage requirement is higher (20V versus 9V), which restricts applicability to systems with higher supply voltages. The operating temperature range is narrower (0°C to 70°C), requiring verification against application specifications.

Alternative for Rail-to-Rail Output: TLE2144AIN

The TLE2144AIN provides rail-to-rail output capability with active product status and extended temperature range (-40°C to 105°C). This part exhibits significantly higher slew rate (45V/µs) and lower input offset voltage (290µV). The minimum supply voltage is lower (4V), expanding applicability to lower-voltage systems. The higher input bias current (700nA) and higher supply current (6.9mA) must be evaluated against application constraints.

Not Recommended for Direct Substitution:

TL3474AIN and TL3474ACN are classified as Last Time Buy with narrower operating temperature ranges. OPA4131PJ is Last Time Buy status. NJM2058D is Last Time Buy status. These parts should be avoided for new designs unless legacy system compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can OP470GPZ be used as a direct replacement for OP470GP?

A: Yes. The OP470GPZ is electrically identical to the OP470GP across all specified parameters. Both parts are quad general-purpose amplifiers in 14-DIP packages with identical slew rate (3V/µs), gain bandwidth product (6MHz), input bias current (15nA), input offset voltage (400µV), and supply voltage range (9V to 36V). The OP470GPZ has active product status, ensuring continued availability.

Q: What is the primary difference between general-purpose and J-FET amplifier substitutes?

A: J-FET amplifiers (LT1058CN#PBF, OPA4131PJ) feature extremely low input bias current (measured in picoamperes) compared to general-purpose designs (measured in nanoamperes). J-FET designs are suitable for high-impedance input applications where input bias current must be minimized. However, J-FET designs typically require higher minimum supply voltages and may have different temperature operating ranges.

Q: Is the 14-DIP package footprint identical across all substitute parts?

A: Yes. All substitute parts listed are configured in 14-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations. This ensures mechanical and electrical compatibility at the board level without requiring PCB redesign.

Q: Can TLE2144AIN be used in applications requiring -40°C operation?

A: Yes. The TLE2144AIN operates across -40°C to 105°C, which encompasses the OP470GP temperature range of -40°C to 85°C. However, the TLE2144AIN exhibits different electrical characteristics (45V/µs slew rate, 700nA input bias current, 6.9mA supply current) that must be verified for circuit compatibility.

Q: What is the significance of "Last Time Buy" product status?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for the product. Existing inventory may be available, but no future production is planned. Parts with Last Time Buy status (TL3474AIN, TL3474ACN, NJM2058D, OPA4131PJ) should not be selected for new designs. These parts are listed for reference only when supporting legacy systems.

Q: Does OPA4227PA require different circuit design considerations?

A: The OPA4227PA maintains the same 14-DIP package and supply voltage range (9V to 36V) as the OP470GP, allowing direct substitution in most applications. However, the significantly lower input bias current (2.5nA versus 15nA) and input offset voltage (10µV versus 400µV) may require circuit verification in precision applications where these parameters were previously not critical.

Q: What is the minimum supply voltage requirement for LT1058CN#PBF?

A: The LT1058CN#PBF requires a minimum supply voltage of 20V, compared to 9V for the OP470GP. This part is suitable only for applications with supply voltages of 20V or higher. Applications with lower supply voltages must use alternative substitutes such as OP470GPZ, OPA4227PA, or NJM2060D#.

Q: Are all substitute parts RoHS compliant?

A: OP470GPZ, NJM2060D#, OPA4131PJ, TL3474AIN, TL3474ACN, LT1058CN#PBF, TLE2144ACN, and TLE2144AIN are ROHS3 compliant. NJM2058D does not specify RoHS status in the provided data. OPA4227PA does not specify RoHS status. Compliance verification is required for applications with regulatory requirements.
