Product details
Overview
LMV822IDG4 from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate at 5 V, and 0.5 mA typical supply current per amplifier across –40°C to 125°C. It serves as a precision signal conditioning and buffering IC in portable sensor interfaces and battery-powered analog front-ends.
For engineers reviewing the LMV822IDG4 datasheet, LMV822IDG4 pinout, LMV822IDG4 application, or LMV822IDG4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, thermal performance data, and validated alternative options for automotive-grade analog signal chains requiring stable offset, wide common-mode range, and rail-to-rail output swing.
Technical Context
The LMV822IDG4 implements a CMOS input stage with rail-to-rail output stage, enabling operation with input common-mode voltage extending to ground and output swing within 100 mV of supply rails under 2 kΩ load at 5 V. Its 5.5 MHz unity-gain bandwidth and 64.2° phase margin ensure stable closed-loop performance with capacitive loads up to 22 pF.
It features no crossover distortion, 72 dB minimum CMRR over –40°C to 125°C, and 42 nV/√Hz input voltage noise at 1 kHz - characteristics critical for high-fidelity amplification in low-noise sensor signal paths and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports single-supply operation from Li-ion battery (3.0–3.7 V) or regulated 3.3 V/5 V rails. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable unity-gain buffer or 10× gain configuration up to ~550 kHz. |
| Slew Rate | 1.9 V/μs typ at 5 V - supports clean 100-kHz sine wave output at 1.9 Vpp without distortion. |
| Input Offset Voltage | 3.5 mV max over –40°C to 125°C - ensures ≤17.5 mV error in 5× gain stage across full temp range. |
| Rail-to-Rail Output | Swings to within 100 mV of VCC+ and GND at 2 kΩ load - preserves dynamic range in low-voltage ADC driver applications. |
| Common-Mode Input Range | –0.3 V to VCC+ – 0.3 V - accepts signals referenced to ground in single-supply systems. |
| Quiescent Current | 0.5 mA typ per amplifier at 5 V - enables dual-channel amplification with <1 mW total dissipation at 5 V. |
Pinout & Package
LMV822IDG4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.9 mm × 4.9 mm body, and exposed pad not present. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input with rail-to-rail swing. |
| 2 | IN− A | Inverting input of Amplifier A - connects to feedback network or differential source. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts reference, sensor, or signal source with ground-referenced common-mode. |
| 4 | GND / VCC− | Ground reference and negative supply terminal - must be low-impedance connection to system ground plane. |
| 5 | IN+ B | Non-inverting input of Amplifier B - independent channel for dual-path signal processing. |
| 6 | IN− B | Inverting input of Amplifier B - supports separate feedback or summing configuration. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; shares same supply and ground. |
| 8 | VCC+ | Positive supply input - accepts 2.5–5.5 V; requires local 0.1 μF ceramic decoupling to GND. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates switching artifacts in Class AB output stage, preserving THD < 0.01% at 1 kHz for audio and sensor signal fidelity. |
| –40°C to 125°C Operation | Qualified for under-hood automotive and industrial control environments without derating. |
| Low Input Bias Current | ≤100 nA max over temperature - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes). |
| High PSRR | ≥75 dB positive supply rejection - rejects ripple on shared 3.3 V rail in mixed-signal PCBs. |
| Amplifier-to-Amplifier Isolation | 135 dB at 1 kHz - prevents crosstalk between channels in dual-sensor or differential pair configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822DR | Same SOIC-8 footprint and pinout; rated for –40°C to 85°C only. | Not suitable for under-hood or extended-temperature industrial use. | Select LMV822DR only for commercial-temperature consumer electronics where cost is prioritized over thermal robustness. |
| TLV2462IDR | Lower 6.4 MHz GBW, higher 0.65 mA ICC, but superior 25 μV max VIO and 10 nV/√Hz noise. | Better for precision DC-coupled applications; less suitable for higher-frequency AC signal paths. | Choose TLV2462IDR when offset drift and noise dominate design requirements over bandwidth and power. |
Compared with LMV822DR and TLV2462IDR, LMV822IDG4 uniquely balances extended temperature operation, 5.5 MHz bandwidth, and sub-1 mW dual-channel power - making it optimal for automotive and industrial signal conditioning where thermal reliability and speed coexist.

FAQ
What is the maximum operating temperature of the LMV822IDG4?
The LMV822IDG4 is characterized for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 stress test guidelines for automotive under-hood applications. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS434I datasheet, and applies to the SOIC-8 (D) package variant with TI's standard thermal derating profile.
Does the LMV822IDG4 support true rail-to-rail input?
No, the LMV822IDG4 does not support rail-to-rail input. Its common-mode input voltage range extends from –0.3 V below GND to VCC+ – 0.3 V, as specified in the 5-V Electrical Characteristics table. While this includes ground (enabling single-supply use), it does not reach the positive rail - distinguishing it from true RRI op-amps like the OPA333.
What is the typical supply current of the LMV822IDG4 at 3.3 V?
At 3.3 V supply and 25°C, the LMV822IDG4 draws 0.45 mA typical per amplifier (0.9 mA total), based on linear interpolation of the 2.7 V (0.45 mA typ) and 5 V (0.5 mA typ) ICC values in the LMV8xxI Electrical Characteristics tables. This value is confirmed across –40°C to 125°C with a maximum of 0.8 mA total.
Can the LMV822IDG4 drive a 600 Ω load rail-to-rail?
Yes, the LMV822IDG4 can drive a 600 Ω load with rail-to-rail output swing: at 5 V supply, it delivers ≥4.75 V high-level and ≤0.25 V low-level output into 600 Ω, per the "Output Swing" specification in the 5-V LMV8xxI Electrical Characteristics table. Performance degrades slightly at lower supplies (e.g., 2.7 V), but remains functional down to 2.5 V.
Is the LMV822IDG4 pin-compatible with the LMV822DGKR?
Yes, the LMV822IDG4 (SOIC-8) and LMV822DGKR (VSSOP-8) share identical pin numbering and function mapping per the "LMV822 . . . D OR DGK PACKAGE (TOP VIEW)" diagram in the datasheet. However, they differ in package size, thermal resistance (θJA = 97°C/W vs. 172°C/W), and moisture sensitivity level - requiring separate PCB footprints and reflow profiles.
