Product details
Overview
LMV822ID from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 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 and buffering IC in portable sensor interfaces and battery-powered analog front-ends.
For engineers reviewing the LMV822ID datasheet, LMV822ID pinout, LMV822ID application, or LMV822ID equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for industrial-grade analog signal chains requiring extended temperature operation and rail-to-rail swing.
Technical Context
The LMV822ID uses a CMOS input stage with rail-to-rail output architecture, enabling full-swing operation from 2.5 V to 5 V supplies while maintaining low input bias current (≤150 nA) and high common-mode rejection (≥70 dB). Its internal compensation ensures stability with capacitive loads up to 22 pF at unity-gain configuration.
It supports single-supply operation with an input common-mode range extending 0.3 V below ground and 0.3 V above VCC, making it suitable for ground-referenced sensor amplification. Amplifier-to-amplifier isolation exceeds 135 dB, minimizing crosstalk in dual-channel configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822DR | Same silicon, but rated for –40°C to 85°C; lower cost; identical pinout and electrical specs at 25°C. | Not qualified for automotive under-hood or industrial high-temp environments where 125°C operation is mandatory. | Select LMV822DR only if ambient temperature remains ≤85°C and lifecycle continuity is prioritized over extended temp grade. |
| TLV2462IDR | Higher VIO (max 2 mV vs. 5.5 mV), lower GBW (6.4 MHz), higher ICC (0.55 mA), same 125°C rating and SOIC-8 package. | Better DC precision but slightly reduced AC performance; preferred in low-frequency sensor calibration circuits. | Choose TLV2462IDR when offset-critical applications (e.g., strain gauge bridges) demand tighter initial VIO, accepting marginal GBW trade-off. |
Compared with LMV822DR, LMV822ID guarantees full spec compliance at 125°C-critical for automotive and industrial deployments-while TLV2462IDR offers superior DC accuracy at comparable temperature rating but with marginally higher power and cost.

FAQ
What is the maximum supply voltage for LMV822ID?
The absolute maximum supply voltage for LMV822ID is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 2.5 V to 5 V, with full electrical specifications guaranteed across that span at temperatures from –40°C to 125°C. At 5 V, LMV822ID achieves its highest gain bandwidth (5.5 MHz) and slew rate (1.9 V/μs), making it optimal for high-fidelity signal conditioning in LMV822ID-based designs.
Does LMV822ID support true single-supply operation with inputs referenced to ground?
Yes, LMV822ID supports true single-supply operation with inputs extending 0.3 V below ground (VICR down to –0.3 V) and up to 0.3 V below VCC. This allows direct connection of ground-referenced sensors (e.g., thermistors, bridge transducers) without external level-shifting circuitry. The input common-mode range is fully specified across –40°C to 125°C, ensuring reliable performance in LMV822ID implementations deployed in harsh thermal environments.
What is the output drive capability of LMV822ID at 5 V supply?
At 5 V supply, LMV822ID delivers ±20 mA output current (sourcing and sinking) into resistive loads, with rail-to-rail swing maintained within 100 mV of both rails at 2 kΩ. Output voltage swing is specified as 4.75 V (high) and 0.17 V (low) at 600 Ω, confirming strong drive strength for driving ADC references, LED bias networks, or small actuators directly. This capability is fully characterized across the –40°C to 125°C range for LMV822ID.
Is LMV822ID pin-compatible with other dual op-amps in SOIC-8 packages?
LMV822ID follows the industry-standard dual op-amp pinout (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+), matching LMV822DR, TLV2462IDR, and OPA2340UA. However, functional equivalence must be verified per application: LMV822ID's 125°C rating, 5.5 MHz GBW, and 0.5 mA ICC differ from many alternatives, so direct substitution requires validation of thermal, bandwidth, and power constraints in the target LMV822ID design.
How does LMV822ID handle capacitive loads?
LMV822ID is internally compensated for unity-gain stability with capacitive loads up to 22 pF, as confirmed in the datasheet's gain/phase margin plots (Figure 17–21). For loads exceeding 22 pF (e.g., long traces or ADC input capacitance), a series resistor (10–50 Ω) between LMV822ID output and the load restores phase margin. This behavior is consistent across all operating conditions and is explicitly validated for LMV822ID in TI's SLOS434I datasheet.
