Product details
Overview
LMV822MMX/NOPB from Texas Instruments is a dual, rail-to-rail output (RRO), low-voltage operational amplifier optimized for 2.5 V to 5.5 V single-supply operation. It delivers 5 MHz gain-bandwidth product, 1.4 V/µs slew rate, and 220 µA per amplifier supply current at 2.7 V - enabling precision signal conditioning in space-constrained portable electronics such as laptop audio subsystems and cellular phone sensor interfaces.
For engineers reviewing the LMV822MMX/NOPB datasheet, LMV822MMX/NOPB pinout, LMV822MMX/NOPB application, or LMV822MMX/NOPB equivalent, key selection criteria include its guaranteed rail-to-rail output swing into 600 Ω (≤160 mV from rail), 3.5 mV max input offset voltage, AEC-Q100 Grade 1 qualification (for automotive variants), and VSSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The LMV822MMX/NOPB implements a CMOS-input, fully differential amplifier core with rail-to-rail output stage capable of sourcing/sinking ≥12 mA into 600 Ω loads. Its internal architecture supports stable operation with capacitive loads up to 100 pF without external compensation, and features 90 dB common-mode rejection ratio (CMRR) and 85 dB power-supply rejection ratio (PSRR) at 5 V supply.
Designed for single-supply systems, it accepts input common-mode voltages down to –0.3 V (with respect to V–) and up to 4.3 V (at 5 V supply), enabling direct interfacing with ground-referenced sensors and ADC drivers. The device operates across –40°C to +85°C industrial temperature range and is specified for 2.5 V, 2.7 V, and 5 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct integration into Li-ion battery-powered systems (3.0–4.2 V nominal) and 3.3 V/5 V logic domains. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffer configurations for audio-band signals (<20 kHz) with <0.1° phase error. |
| Slew Rate | 1.4 V/µs min - sufficient for 10 VPP, 20 kHz sine wave reproduction without slew-induced distortion. |
| Input Offset Voltage | 3.5 mV max - ensures ≤0.07% full-scale error in 5 V-span 12-bit ADC front-ends. |
| Rail-to-Rail Output Swing | 160 mV from rail into 600 Ω - delivers >96% of full supply range for maximum dynamic range in low-voltage data acquisition. |
| Quiescent Current | 0.45 mA typical (dual channel) at 2.7 V - enables always-on sensor amplification in battery-critical applications. |
| Input Bias Current | 90 nA typical - minimizes voltage error across high-impedance source networks (>1 MΩ). |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm, 0.65 mm pitch), thermally enhanced for compact PCB layouts and compatible with standard 0.5 mm stencil apertures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node for feedback network connection; referenced to local ground or virtual ground in inverting configurations. |
| 2 | Non-Inverting Input (Channel A) | Direct interface point for low-level analog sources (e.g., thermistor, microphone bias output). |
| 3 | Output (Channel A) | Capable of driving 600 Ω loads to within 160 mV of rails; requires no external pull-up/down for RRO functionality. |
| 4 | Negative Supply (V–) | Ground reference for single-supply operation; must be connected to system GND or negative rail in split-supply designs. |
| 5 | Positive Supply (V+) | Primary power input; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 6 | Non-Inverting Input (Channel B) | Independent input for second signal path; electrically isolated from Channel A with 135 dB inter-channel isolation. |
| 7 | Inverting Input (Channel B) | Supports independent feedback loop; identical electrical characteristics to Pin 1. |
| 8 | Output (Channel B) | Second independent output; shares same thermal and supply characteristics as Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output (RRO) | Delivers usable output swing within 160 mV of supply rails into 600 Ω - maximizes signal headroom in 3.3 V systems. |
| Low quiescent current | 220 µA per amplifier at 2.7 V - enables dual-channel amplification in sub-1 mA total system budget. |
| Stable with capacitive loads | Operates unconditionally stable with up to 100 pF load capacitance - eliminates need for isolation resistors in LCD or cable-drive applications. |
| Wide input common-mode range | Extends to –0.3 V below V– and up to 4.3 V at 5 V supply - allows direct sensing of ground-referenced transducers. |

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 |
|---|---|---|---|
| MCP6022-E/SN | Higher 10 MHz GBW but 500 µA per amplifier supply current; 2.7 V min supply; no AEC-Q100 qualification. | Better for higher-frequency filtering but less suitable for ultra-low-power always-on sensing. | Select MCP6022-E/SN when bandwidth >7 MHz is required and supply current budget exceeds 0.5 mA per channel. |
| TSV912IDT | Lower 4.5 MHz GBW, 170 µA per amplifier, rail-to-rail input/output, 1.5 V min supply; automotive-grade (AEC-Q100 Grade 1). | Superior input rail-to-rail capability enables true single-supply sensor interfacing down to 1.5 V. | Select TSV912IDT when input common-mode range must include both supply rails or operation below 2.5 V is required. |
Compared with LMV822MMX/NOPB, MCP6022-E/SN trades 110% higher supply current for 100% higher bandwidth, while TSV912IDT offers lower voltage operation and rail-to-rail inputs at the cost of 10% lower gain-bandwidth - making LMV822MMX/NOPB optimal for balanced 2.5–5.5 V, low-noise, low-IQ dual-amplifier roles.

FAQ
What is the maximum operating temperature for LMV822MMX/NOPB?
The LMV822MMX/NOPB is rated for operation from –40°C to +85°C ambient temperature. This industrial temperature range is confirmed in Section 6.3 (Recommended Operating Conditions) of the official TI datasheet SNOS032I. It is not qualified for automotive Grade 1 (–40°C to +125°C); that rating applies only to the LMV822-N-Q1 variant.
Does LMV822MMX/NOPB support rail-to-rail input?
No, LMV822MMX/NOPB supports rail-to-rail output only. Its input common-mode voltage range extends from –0.3 V below V– to 4.3 V above V– at 5 V supply (Section 6.10), but does not reach the positive rail. True rail-to-rail input capability is not specified for LMV822MMX/NOPB and is not present in the LMV82x-N series - only the LMV82x-N-Q1 variants add extended input range in some conditions.
What package type is used for LMV822MMX/NOPB?
LMV822MMX/NOPB uses the VSSOP-8 package (3.00 mm × 3.00 mm body, 0.65 mm lead pitch), as documented in the Device Information table on page 2 of the TI datasheet SNOS032I. This thermally enhanced, surface-mount package is distinct from the SOIC-8 option offered for the LMV822-N and provides superior power dissipation in dense layouts.
Can LMV822MMX/NOPB drive a 600 Ω load to within 200 mV of the supply rails?
Yes - LMV822MMX/NOPB guarantees rail-to-rail output swing to within 160 mV of either rail into a 600 Ω load at 2.7 V supply (Section 6.7, VO parameter). At 5 V supply, output swing is specified to within 250 mV of rails into 600 Ω (Section 6.10), confirming reliable operation well within the 200 mV margin across its full voltage range.
Is LMV822MMX/NOPB pin-compatible with other LMV822 variants?
Yes - all LMV822-N variants (including LMV822MMX/NOPB, LMV822IDR, LMV822MME/NOPB) share identical VSSOP-8 pinout and electrical pin functions per the Pin Functions table on page 5 of SNOS032I. No PCB layout changes are needed when substituting between these VSSOP-packaged versions, though thermal and ESD performance may vary slightly by suffix.
