Product details
Overview
LMV822DRG4 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 85°C. It is used in portable sensor signal conditioning, battery-powered analog front-ends, and precision level-shifting circuits.
For engineers reviewing the LMV822DRG4 datasheet, LMV822DRG4 pinout, LMV822DRG4 application, or LMV822DRG4 equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for space-constrained, low-voltage designs requiring rail-to-rail output swing and minimal quiescent current.
Technical Context
The LMV822DRG4 implements a CMOS input stage with rail-to-rail output stage, enabling full-swing operation from 2.5 V to 5.5 V single-supply rails. Its architecture supports unity-gain stable operation with 64.2° phase margin at 5 V and 600 Ω load, and achieves 135 dB amplifier-to-amplifier isolation to minimize crosstalk in dual-channel configurations.
It features no crossover distortion, a common-mode input voltage range extending 0.3 V below ground and up to 4.3 V at 5 V supply, and maintains 70 dB+ PSRR across 10 Hz–100 kHz - critical for noise-sensitive mixed-signal systems operating near noisy digital supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic without level shifters |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~100 at 50 kHz with stable phase margin |
| Slew Rate | 1.9 V/μs typ at 5 V - sufficient for 100 kHz full-scale sine output into 10 kΩ load |
| Input Offset Voltage | 1 mV typ, 4 mV max (–40°C to 85°C) - ensures ≤10 mV error in 10× gain sensor amplifiers |
| Output Swing | Within 100 mV of rails at 2 kΩ load - delivers true rail-to-rail dynamic range for ADC driver stages |
| Supply Current | 0.5 mA typ per amplifier at 5 V - enables dual op-amp operation under 1 mA total for ultra-low-power systems |
| Common-Mode Range | –0.3 V to 4.3 V at 5 V supply - accepts inputs below ground, supporting bipolar signal conditioning |
Pinout & Package
LMV822DRG4 is packaged in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance θJA = 97°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads down to 600 Ω while maintaining rail-to-rail swing |

| 3 | 1IN+ | Non-inverting input of first amplifier - supports input common-mode down to –0.3 V |
| 4 | GND/VCC− | Ground reference or negative supply - shared return path for both amplifiers |
| 5 | VCC+ | Positive supply - accepts 2.5 V to 5.5 V; decoupling required within 1 cm |
| 6 | 2IN+ | Non-inverting input of second amplifier - electrically isolated from Channel 1 (135 dB crosstalk rejection) |
| 7 | 2IN− | Inverting input of second amplifier - matched bias current to Pin 2 for offset minimization |
| 8 | 2OUT | Output of second amplifier - independent output stage; no internal connection to Pin 1 |
Key Features

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 |
|---|---|---|---|
| TLV2462IDR | Higher supply current (0.65 mA/ch), lower GBW (6.4 MHz), wider VIO range (±2 mV) | Optimized for higher-precision DC-coupled applications; less suitable for high-speed AC signals | Choose TLV2462IDR when offset voltage matching and long-term DC stability outweigh power savings |
| OPA2316IDR | Lower noise (18 nV/√Hz), higher GBW (10 MHz), same 0.5 mA supply current, but only rated to 85°C | Better suited for wideband sensor interfaces and active filters requiring >5 MHz bandwidth | Choose OPA2316IDR when signal bandwidth exceeds 500 kHz and noise performance is critical |
Compared with TLV2462IDR and OPA2316IDR, the LMV822DRG4 offers the best balance of ultra-low power, rail-to-rail output, and robust industrial temperature rating - making it optimal for cost-sensitive, battery-operated, and space-constrained dual-channel analog signal chains where 5.5 MHz bandwidth suffices.

FAQ
What is the maximum operating supply voltage for LMV822DRG4?
The absolute maximum supply voltage for LMV822DRG4 is 5.5 V. Operation above this risks permanent damage. The recommended operating range is 2.5 V to 5.5 V, with full electrical specifications guaranteed across that span. At 5.5 V, output swing remains rail-to-rail, but thermal dissipation must be managed per θJA = 97°C/W.
Does LMV822DRG4 support true rail-to-rail input?
No, LMV822DRG4 does not support rail-to-rail input. Its common-mode input voltage range extends from –0.3 V to VCC – 0.7 V (e.g., –0.3 V to 4.3 V at 5 V). While it accepts inputs below ground, the upper limit is 0.7 V below VCC, so full rail-to-rail input is not supported - only rail-to-rail output is guaranteed.
What is the typical output current drive capability of LMV822DRG4?
LMV822DRG4 delivers ±20 mA typical output current at 5 V supply (sourcing and sinking), with guaranteed minimums of ±15 mA across –40°C to 85°C. This supports driving 600 Ω loads while maintaining rail-to-rail swing and 1.9 V/μs slew rate - sufficient for most ADC drivers and line-level outputs.
Is LMV822DRG4 pin-compatible with other dual op-amps in SOIC-8 packages?
LMV822DRG4 follows the industry-standard SOIC-8 pinout for dual op-amps (1OUT, 1IN−, 1IN+, GND, VCC+, 2IN+, 2IN−, 2OUT), matching TLV2462, OPA2316, and LM358 variants. However, electrical behavior differs significantly - especially input stage type (CMOS vs. bipolar), supply current, and bandwidth - so functional substitution requires circuit validation.
What is the operating temperature range specified for LMV822DRG4?
LMV822DRG4 is characterized and specified for operation from –40°C to +85°C. It is not the "I" variant (LMV822IDRG4), which extends to +125°C. All electrical parameters - including offset voltage, GBW, and output swing - are guaranteed across this full industrial temperature range without derating.
