Texas Instruments LMV772MMX

Overview

LMV772MMX 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, 550µA per amplifier supply current, and 850µV max input offset voltage (25°C), enabling high-accuracy signal conditioning in battery-powered instrumentation and transducer interfaces.

For engineers reviewing the LMV772MMX datasheet, LMV772MMX pinout, LMV772MMX application, or LMV772MMX equivalent, key selection criteria include its guaranteed rail-to-rail output swing into 2kΩ loads (50mV from rails), −40°C to 125°C operating temperature range, AEC-Q100 Grade 1 qualification (LMV772Q variant), and compatibility with low-voltage precision analog front-ends requiring low input bias current (100pA typical) and high CMRR (80dB).

Technical Context

The LMV772MMX employs a CMOS input stage delivering ultra-low input bias current and low 1/f noise, paired with a rail-to-rail output stage using complementary bipolar output transistors to achieve full-swing capability into heavy loads. Its internal compensation ensures unity-gain stability with capacitive loads up to 100pF across the full temperature range.

Designed for precision DC-coupled applications, it supports input common-mode voltage from ground to V+ − 0.9V and maintains large-signal voltage gain ≥98dB (RL = 2kΩ) and PSRR ≥76dB over 2.7V–5V supply. The device's 1.4V/µs slew rate and 3.5MHz GBW enable accurate amplification of signals up to ~100kHz without significant distortion.

Key Specifications

Pinout & Package

FAQ

What is the maximum input common-mode voltage range for LMV772MMX?

The LMV772MMX supports an input common-mode voltage range from ground (0V) to V+ − 0.9V. At V+ = 2.7V, this spans 0V to 1.8V; at V+ = 5.0V, it extends to 0V to 4.1V. This rail-to-rail input capability enables direct interfacing with sensors referenced to ground or mid-supply without external level-shifting circuitry, preserving signal fidelity in single-supply systems.

Does LMV772MMX require external compensation for unity-gain stability?

No, LMV772MMX is internally compensated and unity-gain stable across its full operating conditions. It maintains phase margin ≥79° with 10kΩ load and no additional capacitance, and remains stable with up to 100pF capacitive load on the output. External compensation is unnecessary unless driving >100pF loads or operating in high-EMI environments where layout-induced parasitics may affect stability.

Can LMV772MMX operate from a 2.5V supply?

No, LMV772MMX has a minimum specified supply voltage of 2.7V per its datasheet absolute ratings and electrical characteristics tables. Operation below 2.7V is not guaranteed and may result in degraded parameters including reduced output swing, increased offset voltage, and instability. For 2.5V systems, consider TI's TLV9002 or similar 2.2V-rated alternatives.

What is the thermal resistance (θJA) of the LMV772MMX MSOP-8 package?

The LMV772MMX in the 8-pin MSOP package has a junction-to-ambient thermal resistance (θJA) of 235°C/W, as specified in the "Thermal Resistance" table of the official datasheet. This value assumes standard JEDEC PCB mounting conditions (2-layer board, 1-in² copper pad). Actual thermal performance improves with enhanced PCB copper area or thermal vias beneath the exposed pad (if present), though the MSOP-8 variant does not feature an exposed thermal pad.

Is LMV772MMX pin-compatible with LMV772MME (SOIC-8) or LMV772MM/NOPB?

Yes, LMV772MMX (MSOP-8), LMV772MME (SOIC-8), and LMV772MM/NOPB share identical pinout and electrical specifications. All three variants use the same dual-op-amp functional block diagram and terminal assignments: Pins 1–3 and 5–7 correspond to Amplifier A and B inputs/outputs respectively, Pin 4 is GND, and Pin 8 is V+. Mechanical differences (package size, footprint, thermal performance) do not affect circuit design or layout compatibility at the schematic level.
