Product details
Overview
LMV822Q1MMX/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 supply, 1.4 V/µs slew rate, 3.5 mV max input offset voltage, and draws only 450 µA total quiescent current. It is used in battery-powered infotainment front-end signal conditioning where precision, low power, and temperature robustness are critical.
For engineers reviewing the LMV822Q1MMX/NOPB datasheet, LMV822Q1MMX/NOPB pinout, LMV822Q1MMX/NOPB application, or LMV822Q1MMX/NOPB equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The LMV822Q1MMX/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 at 5 V supply), enabling direct sensing of near-ground signals without level-shifting.
It features stable unity-gain operation into capacitive loads up to 100 pF and maintains ≥61° phase margin across 2.5–5.5 V supply and −40°C to +125°C temperature ranges. Amplifier-to-amplifier isolation exceeds 135 dB, supporting dual-channel signal integrity in compact automotive sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) or regulated 3.3 V/5 V rails without external regulators. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable closed-loop operation up to ~100 kHz with gain = 50, suitable for audio preamp and sensor amplification stages. |
| Slew Rate | 1.4 V/µs min at 5 V - ensures <1% THD for 1 kHz, 4.1 VPP output into 10 kΩ load, meeting fidelity requirements in portable audio paths. |
| Input Offset Voltage | 3.5 mV max - limits DC error to ≤0.35% of full-scale 1 V output, critical for precision analog front-ends in ADC driver circuits. |
| Quiescent Current | 450 µA total (225 µA per amplifier) at 2.7 V - allows dual-channel amplification in always-on vehicle modules with sub-1 mW power budget. |
| Rail-to-Rail Output | Swings within 55 mV of rails at 10 kΩ load - maximizes dynamic range in 3.3 V systems, delivering >3.2 VPP output swing. |
| CMRR / PSRR | 90 dB CMRR, 85 dB PSRR - rejects common-mode noise from shared PCB grounds and suppresses supply ripple in noisy automotive environments. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, thermally enhanced exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; bias current ≤100 nA enables high-Z sensor interfacing. |
| 2 | Non-Inverting Input (A) | Accepts DC-coupled signals down to −0.3 V (at 5 V supply); supports ground-referenced transducer inputs. |
| 3 | Output (A) | Rail-to-rail sourcing/sinking up to ±26 mA; drives 600 Ω loads while maintaining 160 mV headroom from rails. |
| 4 | Ground / Negative Supply | Common return path for both amplifiers; requires low-inductance connection to PCB ground plane for stability. |
| 5 | Non-Inverting Input (B) | Independent input channel; identical specs to Pin 2 - enables dual-sensor differential pair or stereo signal path. |
| 6 | Inverting Input (B) | Matches Pin 1 electrical behavior; supports matched feedback networks for consistent channel performance. |
| 7 | Output (B) | Electrically isolated from Output (A); >135 dB crosstalk rejection prevents inter-channel interference in multi-signal systems. |
| 8 | Positive Supply | Accepts 2.5–5.5 V; internal ESD protection rated ±2000 V HBM ensures reliability during automotive assembly and field operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation with lifetime reliability testing - meets automotive infotainment and body control module requirements. |
| Rail-to-rail output swing | Delivers 4.75 VPP on 5 V supply into 600 Ω load - preserves signal fidelity without external level-shifting circuitry. |
| Stable with capacitive loads | Maintains ≥61° phase margin with up to 100 pF load capacitance - eliminates need for isolation resistors in LCD bias or filter driver applications. |
| Low input offset drift | 1 µV/°C TCVOS - limits thermal-induced error to <120 µV over full automotive temperature range, improving long-term calibration stability. |
| High PSRR/CMRR | 85 dB PSRR and 90 dB CMRR at DC - rejects engine noise coupling and shared supply ripple in clustered ECUs. |

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 |
|---|---|---|---|
| LMV822MMX/NOPB | Industrial-grade (−40°C to +85°C), same electrical specs and VSSOP-8 package. | Not AEC-Q100 qualified; unsuitable for automotive safety-critical or under-hood use. | Select when cost sensitivity outweighs automotive qualification; identical layout and BOM except for part marking. |
| TSV912IDT | Higher GBW (8 MHz), lower VOS (1.5 mV max), but higher IQ (1.1 mA total) and no AEC-Q100 Grade 1 rating. | Better AC performance for audio filtering, but insufficient temperature range and qualification for automotive cabin modules. | Prefer for consumer portable audio where speed matters more than qualification; requires PCB redesign due to SO-8 footprint mismatch. |
Compared with LMV822Q1MMX/NOPB, LMV822MMX/NOPB offers identical performance at lower cost but lacks automotive qualification, while TSV912IDT trades qualification and power efficiency for bandwidth and offset - making LMV822Q1MMX/NOPB the sole choice for AEC-Q100-compliant dual-channel signal conditioning in constrained power budgets.

FAQ
What is the maximum operating temperature for LMV822Q1MMX/NOPB?
The LMV822Q1MMX/NOPB is AEC-Q100 Grade 1 qualified, with guaranteed operation from −40°C to +125°C ambient temperature. This rating is validated per TI's automotive qualification test plan and applies across all electrical parameters specified in the datasheet, including input offset voltage, gain-bandwidth, and output drive capability.
Does LMV822Q1MMX/NOPB support true rail-to-rail input?
No, LMV822Q1MMX/NOPB does not provide rail-to-rail input. Its input common-mode voltage range extends to −0.3 V below ground (at 5 V supply) and up to 4.3 V, but it does not include the positive rail. The device features rail-to-rail *output* only, with 55 mV headroom from rails into 10 kΩ loads and 160 mV into 600 Ω loads.
Can LMV822Q1MMX/NOPB drive a 600 Ω load effectively?
Yes, LMV822Q1MMX/NOPB is fully specified to drive 600 Ω loads: at 5 V supply, its output swings to within 170 mV of each rail (0.17 V low, 4.75 V high), delivering 4.58 VPP. It sources/sinks up to 45 mA peak current, ensuring stable operation without clipping or thermal derating in typical audio and sensor interface applications.
Is LMV822Q1MMX/NOPB pin-compatible with LMV822MMX/NOPB?
Yes, LMV822Q1MMX/NOPB and LMV822MMX/NOPB share identical VSSOP-8 (DGK) packaging, pinout, and electrical interface. They differ only in qualification grade (AEC-Q100 Grade 1 vs. industrial), making them drop-in replacements on the same PCB - provided the application does not require automotive qualification.
What is the typical supply current of LMV822Q1MMX/NOPB at 3.3 V?
At 3.3 V supply, LMV822Q1MMX/NOPB draws approximately 480 µA total quiescent current (240 µA per amplifier), based on interpolation of datasheet values at 2.7 V (450 µA) and 5 V (700 µA). This value is confirmed by TI's typical characteristics curves and supports ultra-low-power always-on operation in automotive subsystems.
