LMV774MT Equivalent & Substitute Parts

Part Overview

The LMV774MT is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and production continuity. The LMV774MT operates across a 2.7V to 5.5V supply range with differential, rail-to-rail output capability, making it suitable for low-power signal conditioning and general analog applications.

Substitute Part Grouping Explanation

Substitution of the LMV774MT is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 14-TSSOP surface-mount package (0.173", 4.40mm Width) to ensure mechanical and electrical compatibility with existing PCB layouts.

Circuit Count: The device must contain four independent amplifier circuits to maintain functional equivalence in multi-channel applications.

Supply Voltage Range: Substitute parts must support the 2.7V to 5.5V supply span to operate within the same power distribution architecture.

Output Configuration: Rail-to-rail output capability is required for maximum signal swing utilization in low-voltage applications.

Electrical Performance: Slew rate, gain-bandwidth product, input offset voltage, and output current drive must be within acceptable ranges for the intended application. Higher performance specifications are acceptable as they provide design margin.

Compliance Status: Active product status and RoHS3 compliance are preferred for new designs and long-term supply assurance.

Substitute parts are grouped into two categories: direct equivalents (same base product number with different packaging) and functional alternatives (different manufacturers with comparable electrical specifications).

Engineering Selection Recommendations

Direct Equivalent (Recommended for Immediate Replacement):

LMV774MT/NOPB is the direct equivalent of the obsolete LMV774MT. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. Selection of LMV774MT/NOPB eliminates design re-qualification and ensures pin-for-pin compatibility with existing layouts.

High-Performance Alternative (Enhanced Specifications):

The ADA4891-4ARUZ family (available in three packaging options: standard tube, Cut Tape & Digi-Reel, and Tape & Reel) provides significantly enhanced performance with 210V/µs slew rate and 105MHz gain-bandwidth product. These CMOS amplifiers maintain the 2.7V to 5.5V supply range and -40°C to 125°C operating temperature. Selection of ADA4891 variants is appropriate when higher bandwidth or faster transient response is required. All three packaging variants (ARUZ, ARUZ-R7, ARUZ-RL) are electrically identical and differ only in delivery format.

Low-Power General-Purpose Alternatives:

LMR934FVJ-E2 (Rohm Semiconductor) offers the lowest supply current at 250µA with comparable input offset voltage (1mV) and slew rate (0.35V/µs). This device is suitable for battery-powered or ultra-low-power applications where the LMV774MT's 600µA supply current is excessive. Operating temperature range is -40°C to 85°C.

LMV324TSG-13 (Diodes Incorporated) provides general-purpose amplification with 340µA supply current and maintains the full -40°C to 125°C temperature range. This device is suitable for cost-sensitive applications requiring extended temperature operation.

Moderate-Performance CMOS Alternatives:

BU7487FV-E2 and BU7487SFV-E2 (Rohm Semiconductor, identical specifications) offer 10V/µs slew rate and 10MHz gain-bandwidth product with 6mA supply current. These devices are suitable for applications requiring moderate bandwidth improvement over the LMV774MT while maintaining reasonable power consumption. Minimum supply voltage is 3V (versus 2.7V for the LMV774MT).

LMR344FVJ-E2 (Rohm Semiconductor) provides 1V/µs slew rate and 2MHz gain-bandwidth product with the lowest supply current (400µA) among CMOS alternatives. Output current capability is 113mA per channel. This device bridges performance and power consumption between general-purpose and high-performance options.

Lower-Performance Alternative:

BD12734FVJ-E2 (Rohm Semiconductor) is suitable only for applications with relaxed bandwidth requirements. This device features 0.4V/µs slew rate and 1MHz gain-bandwidth product. Minimum supply voltage is 1.8V, and maximum operating temperature is 85°C. Output current is limited to 12mA per channel.

All recommended substitutes are RoHS3 compliant and carry active product status, ensuring long-term supply availability and regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can LMV774MT/NOPB be used as a direct replacement for LMV774MT?

A: Yes. LMV774MT/NOPB is electrically and mechanically identical to LMV774MT. The primary differences are active product status and RoHS3 compliance. This is the recommended replacement for obsolete LMV774MT inventory.

Q: What is the key difference between the three ADA4891-4ARUZ variants?

A: ADA4891-4ARUZ, ADA4891-4ARUZ-R7, and ADA4891-4ARUZ-RL are electrically identical. The suffixes indicate packaging format: standard tube, Cut Tape & Digi-Reel, and Tape & Reel respectively. Selection depends on procurement and assembly requirements, not electrical performance.

Q: Can I use ADA4891-4ARUZ in place of LMV774MT without circuit modification?

A: Pin-for-pin compatibility exists, but circuit performance will change significantly. The ADA4891 exhibits 210V/µs slew rate versus 1.4V/µs for LMV774MT, and 105MHz gain-bandwidth product versus 3.5MHz. Input offset voltage is 2.5mV versus 250µV. These differences may require compensation network adjustment or feedback resistor optimization. Functional substitution is possible; direct substitution without re-qualification is not recommended.

Q: Which substitute part has the lowest power consumption?

A: LMR934FVJ-E2 consumes 250µA total supply current (four channels), compared to 600µA for LMV774MT. This represents 58% power reduction. However, slew rate is reduced to 0.35V/µs and maximum operating temperature is 85°C.

Q: Are all substitute parts available in 14-TSSOP package?

A: Yes. All listed substitute parts use 14-TSSOP surface-mount package (0.173", 4.40mm Width), ensuring mechanical compatibility with existing PCB layouts. Package dimensions are identical across all parts.

Q: What is the temperature range limitation for substitute parts?

A: LMV774MT and LMV774MT/NOPB support -40°C to 125°C. ADA4891 variants also support this full range. Rohm Semiconductor alternatives (BD12734FVJ-E2, BU7487FV-E2, BU7487SFV-E2, LMR344FVJ-E2, LMR934FVJ-E2) are limited to -40°C to 85°C or -40°C to 105°C. LMV324TSG-13 supports -40°C to 125°C. Selection must account for application temperature requirements.

Q: Can I use BD12734FVJ-E2 for high-speed signal conditioning?

A: No. BD12734FVJ-E2 features 0.4V/µs slew rate and 1MHz gain-bandwidth product, making it unsuitable for applications requiring fast transient response or high-frequency signal processing. This device is appropriate only for DC and very low-frequency applications.

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

A: LMV774MT, LMV774MT/NOPB, ADA4891 variants, BU7487 variants, and LMV324TSG-13 support 2.7V minimum. LMR344FVJ-E2 supports 2.7V minimum. BD12734FVJ-E2 and LMR934FVJ-E2 support 1.8V minimum. BU7487 variants require 3V minimum. Application power supply design must accommodate these requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. The original LMV774MT is RoHS non-compliant. LMV774MT/NOPB is the compliant version of the same device.
