Product details
Overview
LMV822IDGKRG4 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 - enabling precision signal conditioning in space-constrained portable electronics such as battery-powered sensors and medical instrumentation.
For engineers reviewing the LMV822IDGKRG4 datasheet, LMV822IDGKRG4 pinout, LMV822IDGKRG4 application, or LMV822IDGKRG4 equivalent, key selection criteria include its –40°C to 125°C operating range, MSOP-8 (DGK) package footprint, rail-to-rail output swing down to 100 mV of rails at 2 kΩ load, and absence of crossover distortion in audio and sensor front-end designs.
Technical Context
The LMV822IDGKRG4 implements a complementary input stage with rail-to-rail output using bipolar transistor architecture, supporting single-supply operation from 2.5 V while maintaining CMRR ≥70 dB and PSRR ≥75 dB across its full temperature range. Its internal compensation ensures stable unity-gain operation with 64.2° phase margin at 5 V and 600 Ω load.
It features matched amplifier pairs with 135 dB inter-channel isolation at 1 kHz, enabling dual-channel signal paths without crosstalk degradation in differential sensing and active filtering. Input common-mode range extends from VCC– (GND) to VCC+ – 0.3 V, allowing ground-referenced input signals.
Key Specifications

Pinout & Package
LMV822IDGKRG4 is housed in an 8-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm body, with exposed thermal pad (non-electrical). Pin 1 marked via laser scribe or mold index; pin 1 location confirmed by TI DGK package drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 26 mA sink / 16 mA source with rail-to-rail swing. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (IIB = 40 nA max) for feedback network connection. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts signals from 0 V to VCC+ – 0.3 V common-mode range. |
| 4 | GND / VCC− | Ground reference and negative supply terminal - must be low-impedance path to system GND plane. |
| 5 | VCC+ | Positive supply input - decoupling capacitor (0.1 μF ceramic) required within 5 mm of this pin. |
| 6 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Channel A; shares same VCC+/GND rails. |
| 7 | IN− B | Inverting input of Amplifier B - matched offset and bias performance to Channel A for dual-path consistency. |
| 8 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; 135 dB channel isolation prevents coupling. |
Key Features

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 core silicon, SOIC-8 package, rated for –40°C to 85°C only. | Limited to commercial-temperature industrial or consumer gear; not suitable for under-hood or extended-temperature deployments. | Select when cost sensitivity outweighs temperature requirement and PCB area permits larger SOIC footprint. |
| TLV2462IDGKR | Higher VIO (2 mV max), lower GBW (6.4 MHz), higher ICC (550 μA per amp), same DGK package and temp range. | Better DC precision but higher power; preferred where offset drift dominates over bandwidth. | Choose when sub-2 mV offset and 1.2 μV/°C drift are critical, and 0.05 mA extra supply current is acceptable. |
Compared with LMV822DR, LMV822IDGKRG4 provides guaranteed 125°C operation in a 3×3 mm MSOP - essential for automotive and high-reliability systems; versus TLV2462IDGKR, it trades 0.9 MHz bandwidth and 0.05 mA supply current for lower cost and proven robustness in sensor front-ends.

FAQ
What is the maximum supply voltage rating for LMV822IDGKRG4?
The absolute maximum supply voltage for LMV822IDGKRG4 is 5.5 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. Recommended operating range is 2.5 V to 5 V, with full electrical specifications guaranteed across that span at –40°C to 125°C.
Does LMV822IDGKRG4 support true rail-to-rail input?
No, LMV822IDGKRG4 does not support rail-to-rail input. Its input common-mode voltage range extends from VCC– (GND) to VCC+ – 0.3 V, meaning the maximum allowable input is 0.3 V below the positive rail. It does provide rail-to-rail output swing within 100 mV of both rails under 2 kΩ load.
Is LMV822IDGKRG4 pin-compatible with LMV822DGKR?
Yes, LMV822IDGKRG4 and LMV822DGKR share identical MSOP-8 (DGK) pinout and footprint. The 'I' suffix denotes extended temperature grade (–40°C to 125°C), while standard LMV822DGKR is rated for –40°C to 85°C. Electrical specs are otherwise identical, enabling drop-in replacement where temperature requirements align.
What is the typical output current capability of LMV822IDGKRG4?
At 5 V supply, LMV822IDGKRG4 delivers ±20 mA typical output current - 20 mA sourced when output is near 0 V, and 20 mA sunk when output is near 5 V. Minimum guaranteed values are ±15 mA over –40°C to 125°C, sufficient for driving 2 kΩ loads or moderate-capacitive cables without external buffers.
Can LMV822IDGKRG4 operate from a single 2.5 V supply?
Yes, LMV822IDGKRG4 is fully characterized for single 2.5 V operation. At this voltage, it maintains 3.5 MHz gain bandwidth, 1.7 V/μs slew rate, and rail-to-rail output swing within 200 mV of each rail at 2 kΩ load - making it suitable for ultra-low-voltage IoT sensor nodes powered by lithium-thionyl chloride or energy-harvesting sources.
