Product details
Overview
LMV772MM from Texas Instruments is a dual, rail-to-rail output, low-noise precision operational amplifier optimized for 2.7V–5.5V single-supply operation. It delivers 3.5MHz gain-bandwidth product, 7.5nV/√Hz input voltage noise at 10kHz, and 550µA per amplifier supply current. Its 850µV max input offset voltage (25°C) and −40°C to 125°C operating range support precision transducer amplification in automotive and portable instrumentation.
For engineers reviewing the LMV772MM datasheet, LMV772MM pinout, LMV772MM application, or LMV772MM equivalent, key selection criteria include guaranteed rail-to-rail output swing into 2kΩ loads, low input bias current (100pA typ), extended temperature performance, and compatibility with battery-powered signal chains requiring stable DC accuracy and low broadband noise.
Technical Context
The LMV772MM implements a CMOS input stage with rail-to-rail output using complementary bipolar output transistors, enabling full-swing operation within 50mV of each rail under 2kΩ load. Its 3.5MHz GBW and 1.4V/µs slew rate support unity-gain-stable operation in active filters and precision buffers without external compensation.
Designed for low-voltage precision systems, it features an input common-mode range extending from ground to V+ − 0.9V and maintains ≥80dB CMRR over 0.5V–1.2V VCM at 2.7V supply. Input offset drift is specified at −0.45µV/°C (typ), supporting stable DC gain in thermally varying environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.1µV/°C max offset drift vs. LMV772MM's −0.45µV/°C typical; higher 35µA supply current per amp | Better long-term DC stability in unattended monitoring; less suitable for ultra-low-power battery operation | Select when offset drift dominates error budget over quiescent current |
| MCP6V72-E/SN | Chopper-stabilized; 3µV max VOS; 650µA supply current; 2MHz GBW vs. 3.5MHz | Lower offset enables µV-level measurements; reduced bandwidth limits filter and pulse response | Select when absolute offset is critical and bandwidth <2MHz suffices |
Compared with OPA2333AIDR and MCP6V72-E/SN, the LMV772MM offers optimal balance of low noise (7.5nV/√Hz), moderate power (550µA), and usable bandwidth (3.5MHz) for general-purpose precision amplification where zero-drift complexity or ultra-low offset are not mandatory.

FAQ
What is the maximum input offset voltage specification for LMV772MM over temperature?
The LMV772MM has a maximum input offset voltage of 1.2mV over the full −40°C to 125°C operating range. At room temperature (25°C), the limit is tighter at 1.0mV. This is verified per TI's SNOSA04F datasheet Section 6.4, DC Electrical Characteristics, under 2.7V and 5.0V supply conditions. The LMV772MM's offset drift is typically −0.45µV/°C, contributing predictably to total error across temperature.
Does LMV772MM support true rail-to-rail input common-mode range?
No, the LMV772MM does not support rail-to-rail input. Its input common-mode voltage range is specified from 0V to V+ − 0.9V. For example, at 2.7V supply, valid input range is 0V to 1.8V; at 5.0V supply, it extends to 0V to 4.1V. This limitation is documented in the "Input Common-Mode Voltage Range" parameter of the SNOSA04F datasheet. The LMV772MM does provide rail-to-rail *output* swing.
What package options are available for LMV772MM, and is it pin-compatible with other variants in the family?
The LMV772MM is exclusively offered in the 8-pin MSOP package (JEDEC MO-187AA). It shares identical pinout and footprint with the LMV772M (SOIC-8) and LMV772Q (automotive-grade MSOP-8), enabling direct PCB substitution between these variants. All three use the same dual-amplifier configuration and terminal mapping per the Connection Diagram in Figure 3 of SNOSA04F.
Can LMV772MM drive a 600Ω load while maintaining rail-to-rail output swing?
Yes, the LMV772MM can drive a 600Ω load with rail-to-rail output swing, though with reduced headroom: output swings to within 100mV of each rail under this condition. At 2.7V supply, VO ranges from 0.1V to 2.6V; at 5.0V supply, from 0.15V to 4.85V. This is confirmed in the "Output Swing" specifications (Section 6.4, DC Electrical Characteristics) of the SNOSA04F datasheet for both 2.7V and 5.0V supplies.
Is LMV772MM suitable for automotive applications, and what qualification does it hold?
The standard LMV772MM is not AEC-Q100 qualified. For automotive use, TI offers the LMV772Q variant, which is AEC-Q100 Grade 1 qualified (−40°C to 125°C) and manufactured on an automotive-grade flow. The LMV772MM shares identical electrical specifications and pinout with LMV772Q but lacks the automotive qualification documentation and process controls. Designers targeting automotive ECUs must specify LMV772Q, not LMV772MM.
