LMP7708MM/NOPB Equivalent & Substitute Parts

Part Overview

The LMP7708MM/NOPB is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-VSSOP surface-mount package. This device is classified as Active product status and is designed for applications requiring rail-to-rail output capability with low input bias current and minimal input offset voltage. The LMP7708MM/NOPB operates across a supply voltage range of 2.7 V to 12 V and maintains performance over the industrial temperature range of -40°C to 125°C. Substitute parts are identified when equivalent functional performance can be achieved within the mechanical and electrical constraints of the application, particularly when the primary part faces supply limitations or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMP7708MM/NOPB is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual-circuit configuration (2 circuits minimum)
• Rail-to-rail output capability
• 8-pin surface-mount package (8-TSSOP, 8-MSOP, or equivalent footprint compatibility)
• Supply voltage range compatibility: minimum 2.7 V, maximum 12 V or higher
• Operating temperature range: -40°C to 125°C
• Active product status
• ROHS3 compliance

Secondary Compatibility Parameters:

• Current supply per channel: 1.5 mA or lower preferred for direct substitution
• Current output per channel: 80 mA or higher
• Input bias current: 1.2 µA or lower
• Input offset voltage: 140 µV or lower

The substitute parts identified (ADA4807-2ARMZ, ADA4807-2ARMZ-R7, ADA4896-2ARMZ-R7, MAX4392EUA+) meet all primary criteria. Differences in slew rate, bandwidth, and supply current represent performance variations that do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the LMP7708MM/NOPB.

ADA4807-2ARMZ and ADA4807-2ARMZ-R7: These Analog Devices parts provide voltage feedback amplifier architecture with significantly higher slew rate (250 V/µs) and bandwidth (180 MHz) compared to the LMP7708MM/NOPB. Supply voltage range is 2.7 V to 11 V, which covers the lower operating range of the primary part but does not extend to 12 V maximum. Current supply is reduced to 1 mA per channel pair. The ADA4807-2ARMZ-R7 variant offers higher inventory availability (17,405 units) in Cut Tape & Digi-Reel packaging, while the ADA4807-2ARMZ is supplied in Tube packaging.

ADA4896-2ARMZ-R7: This Analog Devices part features voltage feedback architecture with intermediate slew rate (120 V/µs) and highest bandwidth (230 MHz) among substitutes. Supply voltage range is 3 V to 10 V, which does not extend to the full 2.7 V minimum or 12 V maximum of the primary part. Input offset voltage is superior at 28 µV. Current supply is elevated to 3 mA per channel pair. This part is suitable for applications where the narrower supply range is acceptable and lower offset voltage is beneficial.

MAX4392EUA+: This Maxim Integrated part (now part of Analog Devices Inc.) is optimized for video amplifier applications with the highest slew rate (500 V/µs) among all substitutes. Supply voltage range is 4.5 V to 11 V (single supply) or ±2.25 V to ±5.5 V (dual supply), which does not meet the 2.7 V minimum requirement of the primary part. Current supply is 6 mA. This part is suitable only for applications with supply voltages above 4.5 V.

Selection should prioritize parts with supply voltage ranges that fully encompass the application requirements. ADA4807-2ARMZ-R7 offers the best balance of performance enhancement and supply range coverage for most general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can ADA4807-2ARMZ be used as a direct replacement for LMP7708MM/NOPB in all applications?

A: ADA4807-2ARMZ meets the primary substitution criteria of dual-circuit configuration, rail-to-rail output, 8-pin surface-mount package, and Active product status. However, the maximum supply voltage is 11 V instead of 12 V. If your application operates at or requires 12 V supply, this part is not suitable. For applications operating at 11 V or below, substitution is valid.

Q: What is the difference between ADA4807-2ARMZ and ADA4807-2ARMZ-R7?

A: Both parts are electrically identical. The difference is packaging format: ADA4807-2ARMZ is supplied in Tube packaging, while ADA4807-2ARMZ-R7 is supplied in Cut Tape & Digi-Reel format. ADA4807-2ARMZ-R7 has significantly higher inventory availability (17,405 units vs. 3,300 units). Selection depends on your assembly process requirements and lead time constraints.

Q: Why does ADA4896-2ARMZ-R7 have higher input offset voltage (28 µV) than the LMP7708MM/NOPB (37 µV)?

A: The input offset voltage specification for ADA4896-2ARMZ-R7 is actually lower (better) at 28 µV compared to 37 µV for the LMP7708MM/NOPB. Lower offset voltage indicates superior precision performance.

Q: Is MAX4392EUA+ suitable for low-voltage applications below 4.5 V?

A: No. MAX4392EUA+ has a minimum supply voltage of 4.5 V (single supply) or ±2.25 V (dual supply), which does not meet the 2.7 V minimum requirement of the LMP7708MM/NOPB. This part is not suitable for applications requiring operation below 4.5 V.

Q: Do all substitute parts have the same footprint as LMP7708MM/NOPB?

A: All substitute parts use 8-pin surface-mount packages (8-TSSOP or 8-MSOP) with 0.118" width and 3.00mm pitch, which are mechanically compatible with the LMP7708MM/NOPB 8-VSSOP package. PCB layout and footprint design should accommodate the specific supplier device package variant.

Q: What is the impact of higher slew rate in substitute parts?

A: Substitute parts exhibit significantly higher slew rates (120 V/µs to 500 V/µs) compared to the LMP7708MM/NOPB (5.9 V/µs). Higher slew rate enables faster signal transitions and improved performance in high-frequency applications. This is a performance enhancement that does not negatively impact compatibility in general-purpose applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (ADA4807-2ARMZ, ADA4807-2ARMZ-R7, ADA4896-2ARMZ-R7, MAX4392EUA+) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the LMP7708MM/NOPB.
