Product details
Overview
LMV822DE4 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 - enabling precision signal conditioning in space-constrained portable electronics such as sensor front-ends and battery-powered data acquisition systems.
For engineers reviewing the LMV822DE4 datasheet, LMV822DE4 pinout, LMV822DE4 application, or LMV822DE4 equivalent, key selection criteria include its rail-to-rail output swing (4.85 V high / 0.17 V low at 5 V, RL = 600 Ω), –40°C to 85°C operating range, SOIC-8 package compatibility, and absence of crossover distortion in audio and instrumentation-grade amplification stages.
Technical Context
The LMV822DE4 implements a CMOS input stage with rail-to-rail output using complementary push-pull drivers, supporting single-supply operation down to 2.5 V. Its input common-mode voltage range extends to ground (–0.2 V to 4.2 V at 5 V), enabling direct interfacing with ADC references and microcontroller I/O without level-shifting.
It achieves 5.5 MHz unity-gain bandwidth and 64.2° phase margin with 22 pF capacitive load, ensuring stable operation in unity-gain follower and closed-loop configurations up to 100 kΩ load. Amplifier-to-amplifier isolation exceeds 135 dB, minimizing crosstalk in dual-channel signal paths.

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 | Identical electrical specs and SOIC-8 pinout; same 0.5 mA ICC, 5.5 MHz GBW, and rail-to-rail output | No functional difference - LMV822DE4 and LMV822DR share identical device marking "MV822" and packaging | Select LMV822DR if traceability to TI's original SOIC-8 production lot is required; both meet same JEDEC MS-012 standards |
| TLV2462IDR | Lower GBW (6.4 MHz), higher ICC (0.65 mA), wider VIO range (2 mV typ), and extended –40°C to 125°C rating | Better suited for automotive under-hood applications requiring 125°C operation; less optimal for ultra-low-power portable use | Choose TLV2462IDR only when 125°C operation is mandatory; LMV822DE4 remains preferred for cost-sensitive, battery-powered designs |
Compared with LMV822DR, LMV822DE4 offers identical performance and footprint but differs in tape-and-reel packaging compliance; versus TLV2462IDR, LMV822DE4 provides lower quiescent current and tighter VIO at the expense of maximum temperature rating - making it optimal for consumer and industrial portable equipment where 85°C suffices.

FAQ
What is the operating temperature range for LMV822DE4?
The LMV822DE4 is characterized for operation from –40°C to +85°C. This range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS434I, and applies to all electrical specifications including gain bandwidth, slew rate, and input offset voltage. The LMV822DE4 is not rated for 125°C operation - that specification applies only to the LMV822I variants marked with suffix 'I'.
Does LMV822DE4 support true rail-to-rail input?
No, LMV822DE4 does not support rail-to-rail input. Its input common-mode voltage range is specified as –0.2 V to 4.2 V at 5 V supply (VICR), meaning it accepts inputs 0.2 V below ground and up to 0.3 V below VCC+. While the output swings rail-to-rail (0.17 V to 4.84 V at 5 V, RL = 600 Ω), the input stage is not designed for full-rail common-mode operation - unlike some newer TI op-amps such as the TLV9062.
What is the package type and pin count of LMV822DE4?
LMV822DE4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package, also designated as package drawing 'D' by Texas Instruments. This is a surface-mount, gull-wing leaded package with 1.27 mm pitch, fully compatible with standard SOIC-8 footprints and reflow soldering processes. The pinout matches industry-standard dual op-amp configurations, including TI's own LM2904 and TLV2462 families.
Can LMV822DE4 drive a 600 Ω load effectively?
Yes, LMV822DE4 can drive a 600 Ω load effectively: at 5 V supply, it delivers 4.84 V high-level and 0.17 V low-level output swing into 600 Ω, achieving >96% rail utilization. Its output current capability is ±20 mA (sourcing/sinking), well above the 8.3 mA required for full swing into 600 Ω. Stability is maintained with 64.2° phase margin even with 22 pF capacitive loading, typical of such resistive loads.
Is LMV822DE4 still recommended for new designs?
No - LMV822DE4 is marked "Not Recommended for New Designs" in the official Texas Instruments datasheet SLOS434I. While fully functional and supported for existing production, TI recommends newer alternatives such as the TLV9062 or OPA322 for new projects due to improved specs (lower noise, higher GBW, better PSRR) and active lifecycle status. LMV822DE4 remains viable for legacy design refreshes and cost-sensitive applications where its 5.5 MHz GBW and 0.5 mA/channel current meet requirements.
