Product details
Overview
LMV772QMMX/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, 7.5 nV/√Hz input voltage noise at 10 kHz, 3.5 MHz gain-bandwidth product, and 550 µA supply current per amplifier - used in automotive sensor signal conditioning and precision current sensing.
For engineers reviewing the LMV772QMMX/NOPB datasheet, LMV772QMMX/NOPB pinout, LMV772QMMX/NOPB application, or LMV772QMMX/NOPB equivalent, key selection criteria include guaranteed 2.7V–5.5V operation, rail-to-rail output swing into 2 kΩ loads (≤50 mV from rails), −40°C to +125°C automotive temperature compliance, and low-input-bias-current (100 pA typ) performance for high-impedance transducer interfaces.
Technical Context
The LMV772QMMX/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 architecture supports stable unity-gain operation with capacitive loads up to 500 pF and maintains ≥79° phase margin across supply voltages (2.7V–5.5V) and temperatures (−40°C to +125°C).
It delivers precision performance via trimmed input offset voltage (max 1.2 mV over full temperature range), low drift (−0.35 µV/°C typ), and high DC open-loop gain (100 dB into 2 kΩ). The device operates with input common-mode voltage extending to V− and up to V+ − 0.9 V, enabling ground-sensing capability in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into 3.3 V and 5 V automotive microcontroller domains without level-shifting. |
| Input Offset Voltage (max) | 1.2 mV over −40°C to +125°C - enables accurate DC-coupled amplification of sub-mV sensor signals in engine control units. |
| Gain-Bandwidth Product | 3.5 MHz - allows stable closed-loop gain ≥10 up to ~350 kHz, suitable for anti-aliasing and active filter stages in data acquisition. |
| Voltage Noise Density | 7.5 nV/√Hz at 10 kHz - ensures minimal SNR degradation in precision instrumentation amplifier front-ends. |
| Output Swing (RL = 2 kΩ) | Within 50 mV of rails - preserves dynamic range in low-voltage battery-powered systems (e.g., 3.3 V ADC reference buffers). |
| Supply Current (per amp) | 550 µA - enables dual-amplifier signal chains in always-on automotive modules with <1.2 mW total quiescent power at 3.3 V. |
| Common-Mode Range | 0 V to V+ − 0.9 V - permits direct interfacing to ground-referenced shunt resistors in high-side current sensing. |
Pinout & Package
LMV772QMMX/NOPB is packaged in an 8-pin MSOP (Mini Small Outline Package) with exposed thermal pad, optimized for space-constrained automotive PCBs and thermally demanding environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A output | Delivers rail-to-rail sourced/sunk output current up to ±35 mA; requires local 0.1 µF bypass capacitor. |
| 2 (−INA) | Inverting input A | High-impedance CMOS node (100 pA bias current); sensitive to layout-induced leakage and EMI coupling. |
| 3 (+INA) | Non-inverting input A | DC-coupled to sensor or reference; supports common-mode voltage down to ground for single-supply operation. |
| 4 (V−) | Negative supply | Connected to system ground in single-supply configurations; must be low-impedance for noise immunity. |
| 5 (+INB) | Non-inverting input B | Independent channel input; identical electrical specs to Pin 3 - enables dual-path signal processing without cross-talk. |
| 6 (−INB) | Inverting input B | Matches Pin 2 performance; used for differential pair buffering or independent feedback paths. |
| 7 (OUTB) | Amplifier B output | Electrically isolated from OUTA; supports independent load driving with same rail-to-rail swing specification. |
| 8 (V+) | Positive supply | Accepts 2.7–5.5 V; requires dedicated 0.1 µF + 2.2 µF decoupling close to pin for stability under transient load conditions. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV772MMX/NOPB | Industrial-grade version (−40°C to +125°C), not AEC-Q100 qualified; identical electrical specs and pinout. | Not approved for automotive safety-critical systems; acceptable for non-safety infotainment or body electronics. | Select when AEC-Q100 certification is unnecessary and cost sensitivity outweighs qualification requirements. |
| TSV912IDT | Single-supply RRIO op-amp with 1.1 MHz GBW, 5.7 nV/√Hz noise, and 55 µA supply current - lower bandwidth and noise, but significantly lower power. | Better suited for ultra-low-power always-on sensors; insufficient GBW for >100 kHz active filters or fast-settling data acquisition. | Choose for battery-backed modules where quiescent current <100 µA is mandatory and bandwidth ≤1 MHz suffices. |
Compared with LMV772MMX/NOPB, the LMV772QMMX/NOPB adds formal AEC-Q100 Grade 1 validation for automotive use, while TSV912IDT trades bandwidth and drive strength for ultra-low power - making LMV772QMMX/NOPB optimal for precision, speed, and automotive reliability in one package.

FAQ
What is the maximum operating temperature range for the LMV772QMMX/NOPB?
The LMV772QMMX/NOPB is rated for continuous operation from −40°C to +125°C and is AEC-Q100 Grade 1 qualified, meaning it meets stringent automotive reliability standards for powertrain and chassis applications across this full temperature range.
Does the LMV772QMMX/NOPB support rail-to-rail input common-mode voltage?
No - the LMV772QMMX/NOPB supports rail-to-rail *output* swing but has an input common-mode voltage range of 0 V to V+ − 0.9 V. It does not include rail-to-rail input (RRVI) capability; the inputs cannot accept signals at the positive rail.
Can the LMV772QMMX/NOPB drive a 600 Ω load effectively?
Yes - the LMV772QMMX/NOPB delivers rail-to-rail output swing within 100 mV of each rail into 600 Ω loads at 2.7 V supply, and within 150 mV at 5 V supply. However, output current is limited to ±35 mA, so sustained 600 Ω loading must remain within that boundary to avoid thermal stress.
Is the LMV772QMMX/NOPB pin-compatible with other devices in the LMV77x family?
Yes - the LMV772QMMX/NOPB shares identical 8-pin MSOP pinout with LMV772MMX/NOPB and LMV772IDR. All dual variants (LMV772x) use the same pin configuration; only the LMV771 (SC70-5) and LMV774 (TSSOP-14) differ in package and pin count.
What is the typical input bias current of the LMV772QMMX/NOPB at 25°C?
The typical input bias current of the LMV772QMMX/NOPB is 100 pA at 25°C, with a guaranteed maximum of 250 pA over the full −40°C to +125°C temperature range - enabling high-impedance sensor interfacing without significant offset error from resistor networks.
