Product details
Overview
LMV822QDGKRQ1 from Texas Instruments is a dual, rail-to-rail output operational amplifier qualified for automotive applications, operating from 2.5 V to 5.5 V supply, delivering 5.5 MHz gain bandwidth and 1.9 V/µs slew rate at 5 V, with 0.5 mA typical supply current per amplifier - used in sensor signal conditioning and body control modules.
For engineers reviewing the LMV822QDGKRQ1 datasheet, LMV822QDGKRQ1 pinout, LMV822QDGKRQ1 application, or LMV822QDGKRQ1 equivalent, key selection criteria include automotive-grade temperature range (–40°C to 125°C), low-voltage rail-to-rail output swing, input common-mode range extending to ground, and MSOP-8 packaging for space-constrained ECUs.
Technical Context
The LMV822QDGKRQ1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for low-voltage operation, with no crossover distortion and stable unity-gain performance into capacitive loads up to 22 pF. Its input stage supports common-mode voltages from VCC– (ground) to VCC+ – 0.3 V.
It features internal compensation for 5.5 MHz gain-bandwidth product at 5 V, 64.2° phase margin with 600 Ω load, and amplifier-to-amplifier isolation of 135 dB - enabling dual-channel signal processing without crosstalk in shared-supply automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to 3.3 V or 5 V automotive rails without regulation. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable closed-loop operation up to ~500 kHz with gain ≥10. |
| Slew Rate | 1.9 V/µs typ at 5 V - supports clean amplification of fast-slewing sensor signals (e.g., crankshaft position). |
| Input Offset Voltage | 6 mV max over –40°C to 125°C - ensures <±10 mV error in precision DC-coupled sensor interfaces. |
| Rail-to-Rail Output Swing | Within 100 mV of VCC+ and VCC– at 2 kΩ load - maximizes dynamic range in single-supply systems. |
| Supply Current | 0.7 mA max per amplifier at 125°C - enables dual-channel amplification in thermally constrained modules. |
| Operating Temperature | –40°C to 125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822QDRQ1 | SOIC-8 package (5.0 mm × 6.2 mm), higher thermal resistance (97°C/W vs. 172°C/W), same electrical specs. | Better suited for manual assembly or legacy PCB layouts; less suitable for high-density automotive modules. | Select when board space allows larger footprint and thermal management is less critical. |
| TSV912IQDRQ1 | Higher GBW (8 MHz), lower input bias current (1 pA), but narrower input common-mode range (VCC– + 0.1 V to VCC+ – 1.2 V). | Not compatible with ground-referenced sensors; requires level-shifting for thermistor interfaces. | Choose only if higher speed and ultra-low bias current outweigh loss of ground-sensing capability. |
Compared with LMV822QDRQ1, LMV822QDGKRQ1 offers superior thermal performance and smaller footprint for modern automotive ECUs; versus TSV912IQDRQ1, it provides essential ground-sensing capability at the cost of slightly lower bandwidth and higher bias current.

FAQ
What is the maximum supply voltage for LMV822QDGKRQ1?
The absolute maximum supply voltage for LMV822QDGKRQ1 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, supporting standard automotive 3.3 V and 5 V rails. Exceeding 5.5 V voids warranty and may trigger internal ESD clamp conduction.
Does LMV822QDGKRQ1 support single-supply operation with input signals at ground?
Yes, LMV822QDGKRQ1 supports true single-supply operation with input common-mode voltage extending to VCC– (ground), as confirmed by VICR specification of –0.2 V to 4.2 V at 5 V supply. This enables direct interfacing with grounded sensors like thermistors or potentiometers without level-shifting circuitry - a key advantage over op-amps with limited input range.
What is the thermal resistance (θJA) of the DGK package for LMV822QDGKRQ1?
The junction-to-ambient thermal resistance (θJA) for LMV822QDGKRQ1 in the MSOP-8 (DGK) package is 172°C/W, per TI's SLOS461F datasheet. This value assumes standard JEDEC test conditions (JESD 51-7) on a 2-layer board with 1 in² copper. Actual thermal performance improves with PCB copper pour and thermal vias under the exposed pad.
Is LMV822QDGKRQ1 pin-compatible with LMV822QDRQ1?
No, LMV822QDGKRQ1 (MSOP-8, DGK) and LMV822QDRQ1 (SOIC-8, D) have identical pin functions but different physical footprints and pin spacing. The DGK package uses 0.65 mm pitch and 3.0 mm × 3.0 mm body; SOIC-D uses 1.27 mm pitch and 5.0 mm × 6.2 mm body. PCB layout redesign is required for substitution - they are functionally equivalent but not mechanically interchangeable.
What is the typical output current drive capability of LMV822QDGKRQ1 at 5 V supply?
At 5 V supply, LMV822QDGKRQ1 delivers ±20 mA typical output current (sourcing and sinking) into loads down to 0.5 V from either rail, per the 5-V Electrical Characteristics table. This supports driving 250 Ω loads directly - sufficient for driving ADC reference buffers, LED drivers, or low-impedance filters without external transistors.
