Product details
Overview
LMV822IDR 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 is used in portable sensor signal conditioning, battery-powered analog front-ends, and precision level-shifting circuits.
For engineers reviewing the LMV822IDR datasheet, LMV822IDR pinout, LMV822IDR application, or LMV822IDR equivalent, key selection criteria include its extended temperature range (–40°C to 125°C), rail-to-rail output swing down to 100 mV from rails at 2 kΩ load, input offset voltage ≤5.5 mV over full temperature range, and SOIC-8 package compatibility with legacy PCB layouts.
Technical Context
The LMV822IDR implements a complementary input stage enabling rail-to-rail input common-mode range (–0.2 V to VCC+ – 0.3 V) and rail-to-rail output swing (within 100 mV of supply rails at 2 kΩ). Its 5.5 MHz unity-gain bandwidth and 64.2° phase margin ensure stable operation with capacitive loads up to 22 pF.
Designed for single-supply systems, it features high CMRR (≥70 dB), PSRR (≥75 dB), and amplifier-to-amplifier isolation (135 dB), making it suitable for dual-channel signal processing where crosstalk minimization and supply noise rejection are critical.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - drives loads up to 20 mA sourcing/sinking; rail-to-rail swing. |
| 2 | 1IN− | Inverting input of Amp 1 - accepts signals within –0.2 V to VCC+ – 0.3 V common-mode range. |
| 3 | 1IN+ | Non-inverting input of Amp 1 - matched bias current path; enables precision differential sensing. |
| 4 | GND/VCC− | Ground reference or negative supply - supports single-supply (GND) or split-supply (VCC−) configurations. |
| 5 | 2IN+ | Non-inverting input of Amp 2 - electrically isolated from Amp 1; 135 dB channel separation. |
| 6 | 2IN− | Inverting input of Amp 2 - identical electrical specs to Pin 2; enables independent dual-channel feedback. |
| 7 | 2OUT | Amplifier 2 output - fully independent output stage; no shared internal nodes with Pin 1. |
| 8 | VCC+ | Positive supply - accepts 2.5 V to 5.5 V; PSRR ≥75 dB reduces sensitivity to supply ripple. |
Key Features
| Feature | Design Value |

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 silicon, rated for –40°C to 85°C only; identical electrical specs and pinout. | Not suitable for under-hood or high-ambient industrial use; lower cost for commercial-grade designs. | Select LMV822DR only if operating temperature stays ≤85°C and cost is primary constraint. |
| TLV2462IDR | Lower GBW (6.4 MHz), higher supply current (0.65 mA per amp), wider input offset (±2 mV typ), same SOIC-8 package. | Better DC precision but higher power; less suitable for battery-critical apps. | Choose TLV2462IDR when tighter initial offset (<2 mV) outweighs 30% higher supply current. |
Compared with LMV822DR, LMV822IDR adds guaranteed operation to 125°C without sacrificing bandwidth or power; versus TLV2462IDR, it trades 0.9 MHz bandwidth for 30% lower quiescent current and superior thermal robustness - critical for sealed, fanless enclosures.

FAQ
What is the maximum operating temperature for LMV822IDR?
The LMV822IDR is characterized and guaranteed to operate from –40°C to +125°C. This extended temperature range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS434I, making LMV822IDR suitable for under-hood automotive and industrial control applications where ambient temperatures exceed 85°C.
Does LMV822IDR support rail-to-rail input?
LMV822IDR does not provide rail-to-rail input - its input common-mode voltage range is specified as –0.2 V to VCC+ – 0.3 V (at 25°C), meaning it accepts signals down to 200 mV below ground and up to 300 mV below VCC+. While not rail-to-rail on input, this range includes ground and supports most single-supply sensor interfaces. The LMV822IDR datasheet explicitly confirms this specification in the "Electrical Characteristics" tables.
What is the typical supply current of LMV822IDR at 3.3 V?
At 3.3 V supply, the LMV822IDR draws approximately 0.45 mA per amplifier (0.9 mA total for both channels), interpolated from the 2.7 V (0.45–0.6 mA) and 5 V (0.5–0.7 mA) ICC specifications in the LMV8xxI 2.7-V and 5-V Electrical Characteristics tables. This value is consistent with TI's characterization across the 2.5–5.5 V range and enables dual-channel operation well under 1 mA in 3.3 V systems.
Is LMV822IDR pin-compatible with LMV822DR?
Yes, LMV822IDR is pin-compatible with LMV822DR - both use the same SOIC-8 (D) package with identical pinout, footprint, and soldering profile. The only difference is the extended temperature rating (–40°C to 125°C vs. –40°C to 85°C); all electrical parameters, timing, and layout requirements match exactly. No PCB redesign is needed when upgrading from LMV822DR to LMV822IDR.
What load drive capability does LMV822IDR offer at 5 V supply?
At 5 V supply, LMV822IDR delivers ±20 mA output current (sourcing and sinking), as specified in the "5-V Electrical Characteristics" table under IO parameter. It maintains rail-to-rail output swing within 170 mV of VCC+ and 250 mV of GND when driving 600 Ω, and within 100 mV of both rails at 2 kΩ - enabling direct interface with medium-speed ADCs, LED drivers, and analog switches without external buffers.
