Product details
Overview
LMV822IDRG4 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, and 0.5 mA typical supply current per amplifier at 5 V, operating across –40°C to +125°C. It serves as a precision signal-conditioning front-end in portable sensor interfaces and battery-powered analog signal chains.
For engineers reviewing the LMV822IDRG4 datasheet, LMV822IDRG4 pinout, LMV822IDRG4 application, or LMV822IDRG4 equivalent, key selection criteria include its extended temperature range (–40°C to 125°C), rail-to-rail output swing with <0.25 V headroom at 5 V/600 Ω load, low input offset voltage (≤3.5 mV), and SOIC-8 package compatibility with legacy PCB layouts.
Technical Context
The LMV822IDRG4 implements a complementary input stage enabling rail-to-rail common-mode input voltage range (down to VCC− and up to VCC+ − 0.3 V) and rail-to-rail output swing (within 0.17 V of rails at 5 V/600 Ω). Its 5.5 MHz unity-gain bandwidth and 64.2° phase margin ensure stable operation with capacitive loads up to 22 pF under 600 Ω–100 kΩ resistive loads.
Designed for single-supply operation, it features 75 dB minimum CMRR and PSRR over 0–4 V input common-mode range, with 0.2 pA/√Hz input noise current and 42 nV/√Hz input voltage noise at 1 kHz - supporting high-fidelity amplification in low-noise sensor front-ends without external biasing networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822DRG4 | Same silicon, rated for –40°C to +85°C only; identical electrical specs and pinout | Not suitable for under-hood or high-ambient industrial use where 125°C operation is required | Select LMV822DRG4 only for commercial-grade applications with ambient <85°C |
| TLV2462IDR | Lower GBW (6.4 MHz), higher supply current (0.65 mA/ch), wider offset range (±2 mV), same SOIC-8 package | Better for higher-speed, lower-precision applications; less optimal for ultra-low-power designs | Choose TLV2462IDR when speed >5.5 MHz is needed and 0.15 mA extra per channel is acceptable |
Compared with LMV822DRG4, the LMV822IDRG4 adds guaranteed 125°C operation without trade-offs in noise, bandwidth, or power - making it the sole choice for extended-temperature industrial deployments. Against TLV2462IDR, it trades 0.9 MHz bandwidth for 0.15 mA/ch lower quiescent current and tighter offset, favoring battery longevity over marginal speed gains.

FAQ
What is the maximum operating temperature specification for LMV822IDRG4?
The LMV822IDRG4 is characterized for continuous operation from –40°C to +125°C, meeting automotive and industrial extended-temperature requirements. This rating is verified per TI's SLOS434I datasheet Section "Recommended Operating Conditions", and applies across the full 2.5 V to 5.5 V supply range with no derating needed up to the maximum junction temperature of 150°C.
Does LMV822IDRG4 support true rail-to-rail input common-mode range?
The LMV822IDRG4 supports rail-to-rail output swing but not full rail-to-rail input. Its input common-mode voltage range extends from VCC− (GND) to VCC+ − 0.3 V, as specified in the "Common-mode input voltage range" parameter (VICR) in the 5-V Electrical Characteristics table. This allows ground-referenced sensor inputs while maintaining accuracy near the positive rail.
What is the typical supply current consumption of LMV822IDRG4 at 3.3 V?
At 3.3 V supply, the LMV822IDRG4 draws 0.45 mA typical per amplifier (0.9 mA total), based on interpolation of the 2.7 V (0.45 mA/ch) and 5 V (0.5 mA/ch) ICC specifications in the LMV8xx 2.7-V and 5-V Electrical Characteristics tables. This value holds across –40°C to 125°C per the LMV8xxI characterization.
Can LMV822IDRG4 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes - at 5 V supply, LMV822IDRG4 delivers 0.17 V above GND and 0.15 V below VCC into a 600 Ω load, per the "Output swing" specification in the 5-V Electrical Characteristics table. This confirms usable 4.68 Vpp output swing (93.6% of rail-to-rail) under full-load conditions required for driving legacy analog inputs and transmission lines.
Is LMV822IDRG4 pin-compatible with other dual op-amps in SOIC-8 packages?
LMV822IDRG4 uses the industry-standard SOIC-8 pinout defined in TI's D package drawing: Pin 1 = OUT A, Pin 2 = IN− A, Pin 3 = IN+ A, Pin 4 = GND, Pin 5 = IN+ B, Pin 6 = IN− B, Pin 7 = OUT B, Pin 8 = VCC+. It is pin-compatible with LMV822D, LMV822DR, LMV822DG4, and LMV822ID, enabling drop-in replacement in existing designs where extended temperature range is needed.
