Product details
Overview
LMV772QMM/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, low-noise precision operational amplifier qualified to AEC-Q100 Grade 1 (−40°C to +125°C), with 850 µV max input offset voltage at 25°C, 7.5 nV/√Hz voltage noise at 10 kHz, and 3.5 MHz gain-bandwidth product. It operates from 2.7 V to 5.5 V and delivers 50 mV from rail into 2 kΩ - enabling high-accuracy signal conditioning in automotive sensor interfaces.
For engineers reviewing the LMV772QMM/NOPB datasheet, LMV772QMM/NOPB pinout, LMV772QMM/NOPB application, or LMV772QMM/NOPB equivalent, key selection criteria include guaranteed 2.7 V/5 V operation, automotive-grade temperature qualification, rail-to-rail output swing under load, low input bias current (100 pA typ), and dual-channel layout efficiency for space-constrained PCBs.
Technical Context
The LMV772QMM/NOPB implements a CMOS input stage with ultra-low input bias current and a rail-to-rail output stage using complementary bipolar output transistors. Its open-loop gain exceeds 100 dB into 2 kΩ, supporting stable closed-loop configurations down to unity gain.
It features a fully specified −40°C to +125°C operating range per AEC-Q100 Grade 1, with DC parameters including input offset voltage drift of −0.35 µV/°C (typ) and common-mode input range extending from ground to V+ − 0.9 V - enabling direct interfacing with single-supply sensors and ADC drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports battery-powered and automotive 3.3 V/5 V systems without level-shifting. |
| Input Offset Voltage (max) | 1.2 mV over −40°C to +125°C - ensures ≤1.2 mV error in precision transducer amplification across full automotive temp range. |
| Voltage Noise Density | 7.5 nV/√Hz at 10 kHz - enables clean amplification of medium-frequency sensor signals without added noise floor degradation. |
| Gain-Bandwidth Product | 3.5 MHz - allows stable unity-gain buffer or ≥10× gain at ≥350 kHz for active filter and instrumentation amplifier stages. |
| Rail-to-Rail Output Swing | 50 mV from rail into 2 kΩ - preserves >95% of full-scale dynamic range when driving SAR ADCs or low-voltage logic inputs. |
| Supply Current per Amplifier | 550 µA (typ) at 2.7 V - enables dual-channel precision amplification with <1.2 mA total quiescent current in portable automotive modules. |
| Input Bias Current | 100 pA (typ) at 25°C - minimizes voltage error across high-impedance pH, thermopile, or photodiode sensor sources. |
Pinout & Package
LMV772QMM/NOPB is housed in an 8-pin MSOP (Mini Small Outline Package) with 0.65 mm pitch, optimized for thermal performance (θJA = 235°C/W) and board space reduction in automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; accepts differential input signals up to V+ − 0.9 V. |
| 2 | Non-Inverting Input (A) | High-Z input referenced to system ground or bias voltage; supports single-ended or differential sensor interfaces. |
| 3 | Output (A) | Rail-to-rail output capable of sourcing/sinking ±11 mA into 2 kΩ while maintaining 50 mV headroom from rails. |
| 4 | Ground | Primary reference for both amplifiers; must be low-impedance path to minimize PSRR degradation and crosstalk. |
| 5 | Output (B) | Independent rail-to-rail output; electrically isolated from Output (A) with >100 dB crosstalk rejection at 1 kHz. |
| 6 | Non-Inverting Input (B) | Second high-Z input; enables dual-sensor monitoring or matched-pair instrumentation amplifier front-end design. |
| 7 | Inverting Input (B) | Second feedback node; supports independent gain configuration per channel without shared components. |
| 8 | Supply Voltage (V+) | Single positive supply input; accepts 2.7–5.5 V with 76 dB PSRR (DC) and stable operation under automotive load-dump transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40°C to +125°C, including temperature cycling, HTOL, and ESD testing per JESD22-A114. |
| Rail-to-rail output into 2 kΩ | Delivers 0.05 V to V+ − 0.05 V swing at 25°C, preserving signal fidelity for 12-bit+ ADCs without external level-shifting. |
| Low 1/f noise corner | 12.5 nV/√Hz at 100 Hz - critical for low-frequency sensor applications like pressure or temperature measurement where flicker noise dominates. |
| Ultra-low input bias current | 100 pA typical enables direct connection to megohm-range resistive sensors (e.g., RTDs, strain gauges) without significant offset error. |
| Guaranteed 2.7 V and 5 V specs | All AC/DC parameters validated at both 2.7 V and 5 V supply - eliminates derating uncertainty in mixed-voltage automotive subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV772MM/NOPB | Industrial-grade (−40°C to +125°C), not AEC-Q100 qualified; identical electrical specs and pinout. | Lacks automotive qualification testing - unsuitable for safety-critical or OEM production ECUs. | Select LMV772MM/NOPB only for non-automotive industrial or consumer designs requiring same performance at lower cost. |
| TSV912IDT | Lower noise (5.5 nV/√Hz), higher GBW (8 MHz), but only rated to +105°C; 1.8 V min supply. | Not qualified to AEC-Q100; lacks guaranteed 2.7 V operation and automotive temp range. | Choose TSV912IDT for higher-speed, lower-noise applications outside automotive - e.g., test equipment or medical sensors. |
Compared with LMV772MM/NOPB, the LMV772QMM/NOPB adds formal AEC-Q100 Grade 1 validation for automotive deployment, while TSV912IDT trades qualification for higher bandwidth and lower noise - making LMV772QMM/NOPB the sole choice for production automotive signal chains requiring guaranteed reliability across extended temperature.

FAQ
What is the maximum input offset voltage specification for LMV772QMM/NOPB over its full operating temperature range?
The LMV772QMM/NOPB has a maximum input offset voltage of 1.2 mV across the full −40°C to +125°C operating range, as guaranteed in the datasheet's DC electrical characteristics tables. This value applies to both channels and ensures predictable error contribution in precision sensor amplification circuits throughout automotive thermal extremes.
Does LMV772QMM/NOPB support true rail-to-rail input common-mode range?
No, LMV772QMM/NOPB does not support rail-to-rail input. Its input common-mode voltage range extends from ground to V+ − 0.9 V, as specified in the datasheet. This allows interfacing with ground-referenced sensors but requires biasing above ground for signals near V+.
What package type and footprint does LMV772QMM/NOPB use?
LMV772QMM/NOPB uses an 8-pin MSOP (Mini Small Outline Package) with 0.65 mm lead pitch and exposed thermal pad. It shares the same footprint as SOIC-8 but occupies ~50% less board area, making it ideal for compact automotive modules where thermal performance (θJA = 235°C/W) and density are critical.
Is LMV772QMM/NOPB pin-compatible with LMV772MM/NOPB?
Yes, LMV772QMM/NOPB is pin-compatible and functionally identical to LMV772MM/NOPB in all electrical and mechanical aspects - differing only in qualification status (AEC-Q100 Grade 1 vs. industrial grade). No PCB redesign is needed when upgrading from LMV772MM/NOPB to LMV772QMM/NOPB for automotive qualification.
What is the minimum supply voltage required for guaranteed operation of LMV772QMM/NOPB?
The LMV772QMM/NOPB is guaranteed to operate down to 2.7 V, with full DC and AC specifications validated at this voltage. Operation below 2.7 V is not characterized and may result in degraded parameters such as reduced output swing, increased offset, or instability - particularly at temperature extremes.
