LMP7708MA/NOPB Equivalent & Substitute Parts

Part Overview

The LMP7708MA/NOPB is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This dual-channel rail-to-rail amplifier is designed for applications requiring low input bias current and precision signal conditioning across a 2.7V to 12V supply range. The device is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters of this product category, maintaining compatibility with existing circuit designs and PCB layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMP7708MA/NOPB is determined by strict adherence to the following criteria:

Mandatory Compatibility Parameters:

• Dual-channel (2 circuit) general-purpose amplifier architecture
• Rail-to-rail output configuration
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply voltage range: 2.7V to 12V minimum and maximum
• Operating temperature range: -40°C to 125°C
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

Electrical Performance Considerations: Substitute parts must maintain functional equivalence within the specified supply voltage and temperature operating windows. Variations in slew rate, gain bandwidth product, input bias current, input offset voltage, and output current are permitted within the constraints of the application circuit design.

All identified substitute parts meet the mandatory compatibility parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: TS9222IDT and TS9222IYDT

The TS9222IDT and TS9222IYDT are functionally equivalent substitutes for the LMP7708MA/NOPB. Both devices are manufactured by STMicroelectronics and carry AEC-Q100 automotive qualification, indicating compliance with automotive-grade reliability standards. These parts maintain identical supply voltage ranges, operating temperature specifications, and package geometry. The primary electrical differences are reduced slew rate (1.3V/µs versus 5.9V/µs) and lower gain bandwidth product (4MHz versus 15MHz), which are acceptable in applications not requiring high-speed signal conditioning.

Secondary Substitute: TS952IYDT

The TS952IYDT is a functional substitute with additional electrical constraints. This device exhibits the lowest slew rate (1.0V/µs) and gain bandwidth product (3MHz) among the substitute options, along with significantly reduced output current per channel (10mA versus 86mA). The TS952IYDT is suitable for low-speed, low-power applications within the specified supply and temperature ranges. This part also carries AEC-Q100 automotive qualification.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and operate across the identical -40°C to 125°C temperature range. The STMicroelectronics substitutes carry AEC-Q100 qualification, which exceeds the commercial-grade specification of the original LMP7708MA/NOPB.

Frequently Asked Questions (FAQ)

Q: Can TS9222IDT and TS9222IYDT be used interchangeably with LMP7708MA/NOPB?

A: Yes. Both TS9222 variants meet all mandatory compatibility parameters: dual-channel general-purpose amplifier, rail-to-rail output, 8-SOIC package, 2.7V to 12V supply range, -40°C to 125°C operating temperature, ROHS3 compliance, and MSL 1 rating. Electrical performance differences in slew rate and bandwidth are acceptable in applications not requiring high-frequency response.

Q: What are the key electrical differences between LMP7708MA/NOPB and TS9222 variants?

A: The LMP7708MA/NOPB provides higher slew rate (5.9V/µs versus 1.3V/µs) and greater gain bandwidth product (15MHz versus 4MHz). The LMP7708MA/NOPB also exhibits lower input bias current (0.2pA versus 15nA) and lower input offset voltage (37µV versus 500µV). These differences are application-dependent and do not affect pin-level compatibility or package footprint.

Q: Is TS952IYDT suitable as a direct replacement?

A: TS952IYDT is a functional substitute within the specified electrical and mechanical parameters. However, this device has significantly reduced output current per channel (10mA versus 86mA) and lower slew rate (1.0V/µs). Applications requiring higher output current or faster signal transitions should use TS9222IDT or TS9222IYDT instead.

Q: Are all substitute parts automotive-qualified?

A: Yes. All three STMicroelectronics substitute parts (TS9222IDT, TS9222IYDT, and TS952IYDT) carry AEC-Q100 qualification. The original LMP7708MA/NOPB is commercial-grade. Automotive applications may benefit from the automotive qualification of the substitute parts.

Q: Do the substitute parts require PCB layout modifications?

A: No. All substitute parts use the identical 8-SOIC (0.154", 3.90mm width) package. Pin-to-pin compatibility is maintained, and no PCB layout changes are required for mechanical or electrical integration.

Q: What is the inventory status of substitute parts?

A: TS9222IDT: 1120 pcs in stock. TS9222IYDT: 6769 pcs in stock. TS952IYDT: 23675 pcs in stock. Availability may vary by supplier and time of inquiry.
