Substitute Part Grouping Explanation

Substitution compatibility for the LMP7704MT is determined by the following critical parameters: four-circuit configuration, rail-to-rail output capability, 14-TSSOP package format, surface-mount technology, and operating temperature range of -40°C to 125°C. All substitute parts must maintain these core mechanical and functional specifications to ensure direct replacement without circuit redesign.

The substitute parts are grouped into two categories based on electrical performance characteristics:

Category 1: Direct Functional Equivalents — Parts with comparable slew rate (0.3 V/µs to 1.3 V/µs), gain bandwidth product (450 kHz to 4 MHz), and output current capability (80 mA to 86 mA). These parts support applications requiring similar signal processing speeds and output drive capability.

Category 2: Low-Power Alternatives — Parts with significantly reduced supply current (20 µA to 1.2 µA) and lower slew rate (0.0045 V/µs to 0.05 V/µs), suitable for power-constrained applications where bandwidth requirements are reduced.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and surface-mount 14-TSSOP packaging identical to the main part.

Engineering Selection Recommendations

LMP7704MT/NOPB — Direct packaging variant of the main part with identical electrical specifications. This is the preferred substitute when the original LMP7704MT reaches end-of-life. Both parts maintain Last Time Buy or Active status with Texas Instruments and are functionally interchangeable. Packaging differs only in tube versus reel format.

TS924AIPT and TS924AIYPT — STMicroelectronics general-purpose amplifiers with enhanced gain bandwidth product (4 MHz versus 2.5 MHz) and improved slew rate (1.3 V/µs versus 1.1 V/µs). Both carry AEC-Q100 automotive qualification and Active product status. These parts are suitable for applications requiring higher bandwidth performance within the same supply voltage and temperature operating range. TS924AIYPT is supplied in Tape & Reel format with higher inventory availability (15,300 units).

TS924IPT — General-purpose amplifier with identical performance characteristics to TS924AIPT/AIYPT variants but with higher input offset voltage (3 mV versus 900 µV). Carries AEC-Q100 qualification and Active status. Highest inventory availability (33,700 units) among STMicroelectronics substitutes.

TS954IPT — General-purpose amplifier with slew rate (1 V/µs) and gain bandwidth product (3 MHz) comparable to the LMP7704MT. Carries AEC-Q100 automotive qualification and Active product status. Suitable for applications requiring automotive-grade reliability across the full -40°C to 125°C temperature range.

OP496HRUZ-REEL — Analog Devices CMOS amplifier with significantly reduced output current capability (4 mA versus 86 mA) and lower gain bandwidth product (450 kHz versus 2.5 MHz). Suitable only for low-power signal conditioning applications where output drive requirements are minimal. Not recommended for applications requiring high output current.

TS934IPT — Low-power alternative with reduced supply current (20 µA versus 3.2 mA) and lower slew rate (0.05 V/µs). Operating temperature limited to -40°C to 105°C. Suitable for battery-powered or ultra-low-power applications where bandwidth is not critical.

TS944AIPT and TS944IPT — Ultra-low-power alternatives with minimal supply current (1.2 µA) and extremely low slew rate (0.0045 V/µs). Operating temperature limited to -40°C to 85°C. These parts are suitable only for applications with minimal bandwidth requirements and strict power consumption constraints. Not suitable for high-speed signal processing.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 14-TSSOP surface-mount packaging. Selection should be based on specific application requirements for bandwidth, output current, power consumption, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I directly replace LMP7704MT with LMP7704MT/NOPB?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range (-40°C to 125°C), and 14-TSSOP packaging. The only difference is packaging format: LMP7704MT uses tube packaging while LMP7704MT/NOPB uses reel format. No circuit modifications are required.

Q: What is the key difference between TS924AIPT and TS924IPT?

A: Both parts are STMicroelectronics general-purpose amplifiers with identical slew rate (1.3 V/µs) and gain bandwidth product (4 MHz). The primary difference is input offset voltage: TS924AIPT specifies 900 µV while TS924IPT specifies 3 mV. Both carry AEC-Q100 automotive qualification and are suitable for the same applications. TS924IPT has higher inventory availability (33,700 units).

Q: Can I use OP496HRUZ-REEL as a direct replacement for LMP7704MT?

A: No. While OP496HRUZ-REEL maintains the same 14-TSSOP package and rail-to-rail output capability, it has significantly reduced output current (4 mA versus 86 mA) and lower gain bandwidth product (450 kHz versus 2.5 MHz). This part is suitable only for low-power signal conditioning applications where output drive requirements are minimal.

Q: What is the operating temperature limitation for TS944AIPT and TS944IPT?

A: Both TS944 variants are rated for -40°C to 85°C operation, which is narrower than the LMP7704MT specification of -40°C to 125°C. These parts are not suitable for applications requiring operation above 85°C. Verify application temperature requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, identical to the LMP7704MT.

Q: Which substitute part has the lowest power consumption?

A: TS944AIPT and TS944IPT have the lowest supply current at 1.2 µA per four-channel device. These parts are suitable for battery-powered or ultra-low-power applications. However, they have extremely low slew rate (0.0045 V/µs) and gain bandwidth product (10 kHz), limiting use to applications with minimal bandwidth requirements.

Q: Can I use TS934IPT for high-speed signal processing?

A: No. TS934IPT has a slew rate of only 0.05 V/µs and gain bandwidth product of 100 kHz, making it unsuitable for high-speed applications. This part is designed for low-power, low-bandwidth signal conditioning. For applications requiring bandwidth comparable to LMP7704MT (2.5 MHz), use TS924AIPT, TS924AIYPT, TS924IPT, or TS954IPT.

Q: Do all substitute parts use the same 14-TSSOP package?

A: Yes. All substitute parts use identical 14-TSSOP (0.173", 4.40mm Width) surface-mount packaging. No PCB layout modifications are required for mechanical compatibility.

Q: Which substitute parts carry automotive qualification?

A: TS924AIPT, TS924AIYPT, TS924IPT, TS934IPT, and TS954IPT all carry AEC-Q100 automotive qualification. These parts are suitable for automotive and industrial applications requiring automotive-grade reliability.

Q: What is the minimum supply voltage for each substitute part?

A: LMP7704MT, LMP7704MT/NOPB, TS924AIPT, TS924AIYPT, TS924IPT, TS934IPT, and TS954IPT all support minimum supply voltage of 2.7 V. TS944AIPT and TS944IPT support 2.5 V minimum. OP496HRUZ-REEL requires minimum 3 V supply voltage. Verify application supply voltage requirements before selection.
