Product details
Overview
LMV822IDE4 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 across –40°C to 125°C. It is used in portable sensor signal conditioning, battery-powered medical devices, and industrial analog front-ends where space and power efficiency are critical.
For engineers reviewing the LMV822IDE4 datasheet, LMV822IDE4 pinout, LMV822IDE4 application, or LMV822IDE4 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), input common-mode range extending to ground, and guaranteed operation over extended temperature (–40°C to 125°C) in SOIC-8 packaging.
Technical Context
The LMV822IDE4 implements a complementary input stage enabling rail-to-rail input common-mode voltage range down to VCC– (ground in single-supply mode) and rail-to-rail output swing within 100 mV of each rail under 600 Ω load. Its internal compensation ensures stable unity-gain operation with phase margin ≥64.2° at 5 V and 600 Ω load.
It features no crossover distortion due to Class AB output stage design, supports single-supply operation from 2.5 V, and maintains 135 dB amplifier-to-amplifier isolation-critical for dual-channel signal integrity in mixed-signal systems.
Key Specifications

Pinout & Package
LMV822IDE4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.91 mm × 4.9 mm body size, and exposed pad not present. Pinout follows industry-standard dual op-amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - Drives loads up to 20 mA sourcing/sinking; rail-to-rail swing enables full utilization of ADC reference. |
| 2 | IN− A | Inverting input A - High-impedance node; common-mode range includes ground for single-supply transducer interfaces. |
| 3 | IN+ A | Non-inverting input A - Matches IN− A bias current (≤30 nA); enables precision differential sensing with matched resistors. |
| 4 | GND / VCC− | Power return / negative supply - Shared ground reference for both amplifiers; decoupling capacitor required at pin. |
| 5 | IN+ B | Non-inverting input B - Electrically isolated from Channel A; supports independent signal paths without crosstalk (>135 dB isolation). |
| 6 | IN− B | Inverting input B - Matches Channel A's input characteristics; allows identical feedback networks for matched gain/phase response. |
| 7 | OUT B | Amplifier B output - Fully independent output stage; capable of driving separate loads or cascaded stages without interaction. |
| 8 | VCC+ | Positive supply - Accepts 2.5–5.5 V; PSRR >75 dB ensures immunity to digital supply noise in mixed-signal PCBs. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Class AB output stage eliminates dead-zone nonlinearity, preserving THD <0.01% at 1 kHz for audio and sensor signal fidelity. |
| Rail-to-Rail Output | Swings within 100 mV of both rails at 5 V/600 Ω - Maximizes dynamic range when driving SAR or delta-sigma ADCs directly. |
| Extended Temperature Range | Specified from –40°C to 125°C - Validated for under-hood automotive sensors and industrial motor control feedback loops. |
| Low Input Bias Current | ≤30 nA max (–40°C to 125°C) - Minimizes offset error in high-impedance pH or thermocouple amplifier circuits. |
| High CMRR | ≥70 dB over full temperature range - Rejects common-mode noise from shared ground traces or EMI-coupled supply lines. |

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 |
|---|---|---|---|
| TLV2462IDR | Lower GBW (6.4 MHz), higher supply current (650 µA per amp), wider input offset (2 mV typ), same SOIC-8 package. | Optimized for precision DC applications over speed; less suitable for >100 kHz AC-coupled sensor signals. | Select TLV2462IDR when ultra-low offset drift (<2 µV/°C) and lower noise (22 nV/√Hz) outweigh bandwidth needs. |
| OPA2316IDR | Higher GBW (10 MHz), lower noise (11 nV/√Hz), same 0.5 mA supply current, but only rated to 85°C (not 125°C). | Not qualified for under-hood or high-ambient industrial environments requiring extended temperature operation. | Choose OPA2316IDR for high-speed, low-noise applications below 85°C ambient, such as active filters or fast-settling data acquisition. |
Compared with TLV2462IDR and OPA2316IDR, LMV822IDE4 uniquely balances 5.5 MHz bandwidth, 125°C operation, and sub-1 mA dual-channel consumption-making it optimal for ruggedized, battery-constrained embedded systems where thermal reliability and power efficiency are co-prioritized.

FAQ
What is the operating temperature range specified for LMV822IDE4?
The LMV822IDE4 is characterized for operation from –40°C to +125°C. This extended temperature grade is confirmed in the TI datasheet SLOS434I (Rev. July 2006) under "Recommended Operating Conditions" and applies specifically to the 'I' suffix variants like LMV822IDE4. It is validated for use in automotive under-hood and industrial control environments where ambient temperatures exceed 85°C.
Does LMV822IDE4 support true rail-to-rail input and output operation?
LMV822IDE4 provides rail-to-rail output swing (within 100 mV of VCC+ and VCC– at 5 V, RL = 600 Ω) and rail-to-rail input common-mode range (–0.3 V to 4.3 V at 5 V), which includes ground. However, its input stage does not achieve full rail-to-rail differential input voltage capability-maximum VID is ±VCC. The device is not a full rail-to-rail input/output (RRIO) op-amp, but its input range to ground and output swing to rails meet most single-supply sensor interface requirements.
What package type and pin count does LMV822IDE4 use?
LMV822IDE4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package, designated as 'D' in TI's packaging nomenclature. Its dimensions are 3.91 mm × 4.9 mm with 1.27 mm lead pitch. This is distinct from the MSOP-8 (DGK) variant; LMV822IDE4 is exclusively offered in SOIC-8 per TI's packaging addendum (2016), and the 'E4' suffix denotes lead-free, RoHS-compliant finish.
How does the supply current of LMV822IDE4 compare across voltage and temperature?
LMV822IDE4 draws 0.5 mA typical supply current per amplifier at 5 V and 25°C, rising to 0.9 mA maximum across –40°C to 125°C. At 2.7 V, typical ICC is 0.45 mA per amplifier. The device exhibits monotonic increase with supply voltage and moderate positive temperature coefficient-confirmed in Figure 3 of the datasheet-enabling predictable power budgeting in wide-input-range battery systems.
Is LMV822IDE4 recommended for new designs?
No-LMV822IDE4 is marked "Not Recommended for New Designs" in the official Texas Instruments datasheet (SLOS434I, Rev. July 2006) and packaging addendum. While fully functional and supported for existing production, TI advises migration to newer alternatives such as the TLV9062 or OPA2316 for new projects due to improved specs, enhanced ESD robustness, and active lifecycle status. LMV822IDE4 remains available through authorized distributors for legacy program continuity.
