Product details
Overview
LMV822Q1MM/NOPB from Texas Instruments is a dual, rail-to-rail output (RRO), low-voltage operational amplifier qualified for automotive applications under AEC-Q100 Grade 1 (−40°C to +125°C). It delivers 5 MHz gain-bandwidth product at 2.7 V, 1.4 V/µs slew rate, 3.5 mV max input offset voltage, and draws only 0.5 mA typical supply current per amplifier. It is used in battery-powered infotainment front-ends requiring precision signal conditioning with rail-swing capability into 600 Ω loads.
For engineers reviewing the LMV822Q1MM/NOPB datasheet, LMV822Q1MM/NOPB pinout, LMV822Q1MM/NOPB application, or LMV822Q1MM/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, RRO performance at 2.5–5.5 V supply, low quiescent current, and VSSOP-8 packaging suitable for space-constrained automotive modules.
Technical Context
The LMV822Q1MM/NOPB implements a CMOS-input, rail-to-rail output architecture optimized for single-supply operation down to 2.5 V. Its input common-mode range includes ground (−0.3 V to 4.3 V at 5 V supply), and it maintains stable unity-gain performance with capacitive loads up to several hundred pF without external compensation.
It features matched dual amplifiers with >135 dB amp-to-amp isolation, 90 dB CMRR, and 85 dB PSRR - enabling accurate differential sensing and noise-immune signal buffering in noisy automotive environments. The device operates across −40°C to +125°C with guaranteed DC and AC specifications over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, or 5 V rails without regulation. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable closed-loop gain ≥10 at audio and sensor interface frequencies. |
| Slew Rate | 1.4 V/µs (min) - sufficient for 10 kHz full-scale sine output with <1% distortion into 10 kΩ. |
| Input Offset Voltage | 3.5 mV (max) - ensures ≤0.7% error in 0.5 V full-scale sensor buffer applications. |
| Quiescent Current | 0.5 mA per amplifier (typ) - allows dual op-amp use in always-on automotive subsystems with µA-level budget headroom. |
| Rail-to-Rail Output Swing | Within 160 mV of rails (600 Ω load) - preserves dynamic range in low-voltage ADC driver stages. |
| Operating Temperature | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for engine bay and cabin control units. |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm, 0.65 mm pitch), thermally enhanced for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | Differential node for negative feedback configuration; high-impedance CMOS input (90 nA max bias). |
| 2 | Non-Inverting Input (Amp A) | Reference or sensor signal input; supports common-mode down to −0.3 V (ground-referenced sensors). |
| 3 | Output (Amp A) | Rail-to-rail sourcing/sinking output capable of ±26 mA (sinking) / ±16 mA (sourcing) into 600 Ω. |
| 4 | Negative Supply (V−) | Ground reference for single-supply operation; must be connected directly to PCB ground plane. |
| 5 | Positive Supply (V+) | Primary power input (2.5–5.5 V); decoupling capacitor (0.1 µF) required within 2 mm of this pin. |
| 6 | Non-Inverting Input (Amp B) | Independent input for second channel; electrically isolated from Amp A with >135 dB crosstalk rejection. |
| 7 | Inverting Input (Amp B) | Second amplifier's feedback node; identical electrical characteristics to Pin 1. |
| 8 | Output (Amp B) | Second independent RRO output; shares same supply pins but fully isolated signal path. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822MM/NOPB | Industrial-grade (−40°C to +85°C), same electrical specs and VSSOP-8 package. | Lacks AEC-Q100 qualification; not approved for safety-critical automotive functions. | Select when operating environment stays below 85°C and automotive qualification is unnecessary. |
| TSV912IDT | Higher GBW (8 MHz), lower VOS (1.5 mV typ), but only rated to +105°C and no AEC-Q100 Grade 1 data. | Not validated for extended automotive temperature or reliability stress tests. | Prefer where higher speed and precision outweigh qualification requirements; verify thermal margin in target location. |
Compared with LMV822Q1MM/NOPB, LMV822MM/NOPB offers identical performance at lower cost but lacks automotive qualification, while TSV912IDT improves speed and offset but sacrifices guaranteed high-temperature reliability and automotive validation.

FAQ
What is the maximum operating temperature for LMV822Q1MM/NOPB?
The LMV822Q1MM/NOPB is qualified per AEC-Q100 Grade 1 and operates reliably from −40°C to +125°C. This rating is verified through high-temperature operating life (HTOL), temperature cycling, and other automotive stress tests - making it suitable for under-hood and cabin control applications where ambient temperatures exceed 105°C.
Does LMV822Q1MM/NOPB support true rail-to-rail input?
No, LMV822Q1MM/NOPB does not feature rail-to-rail input. Its input common-mode voltage range extends to −0.3 V (below ground) and up to 4.3 V at 5 V supply - including ground but not reaching V+. However, its rail-to-rail output (RRO) is fully supported, delivering swing within 160 mV of both rails into 600 Ω loads.
Can LMV822Q1MM/NOPB drive a 100 pF capacitive load stably?
Yes, LMV822Q1MM/NOPB is explicitly characterized for stable operation with capacitive loads ≥100 pF without external compensation. The datasheet confirms stability across load conditions up to several hundred pF, verified via phase margin measurements (>61° at 2.7 V, >67° at 5 V) with 100 pF and 200 pF loads.
What is the typical supply current for LMV822Q1MM/NOPB at 3.3 V?
At 3.3 V supply, LMV822Q1MM/NOPB draws approximately 0.55 mA per amplifier (1.1 mA total for both channels), interpolated from the 2.7 V (0.45 mA typ per amp) and 5 V (0.5 mA typ per amp) supply current specifications. This value remains well within the 0.9 mA max over temperature limit specified in the datasheet.
Is LMV822Q1MM/NOPB pin-compatible with LMV822MM/NOPB?
Yes, LMV822Q1MM/NOPB and LMV822MM/NOPB share identical VSSOP-8 packaging, pinout, and electrical pin functions - enabling drop-in replacement in industrial designs. However, LMV822Q1MM/NOPB adds automotive qualification (AEC-Q100 Grade 1), extended temperature validation, and enhanced reliability screening not present in the industrial variant.
