Product details
Overview
LMV822DRE4 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 85°C. It is used in portable sensor signal conditioning and battery-powered analog front-ends.
For engineers reviewing the LMV822DRE4 datasheet, LMV822DRE4 pinout, LMV822DRE4 application, or LMV822DRE4 equivalent, key selection criteria include rail-to-rail output swing with ±0.2 V headroom at 5 V/600 Ω, input common-mode range extending to ground, and guaranteed operation over industrial temperature range without thermal derating.
Technical Context
The LMV822DRE4 implements a complementary input stage enabling rail-to-rail input common-mode voltage range down to ground and rail-to-rail output swing within 0.2 V of supply rails under 600 Ω load. Its 5.5 MHz unity-gain bandwidth and 64.2° phase margin ensure stable closed-loop operation with capacitive loads up to 22 pF.
It features no crossover distortion due to its Class AB output stage design and achieves 135 dB amplifier-to-amplifier isolation-critical for dual-channel signal paths where crosstalk must be minimized in mixed-signal PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, two-cell alkaline, and 3.3 V/5 V system rails without level-shifting. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable unity-gain buffers and 2nd-order active filters up to ~500 kHz. |
| Slew Rate | 1.9 V/μs typ at 5 V - supports 10-bit ADC driving with <1 LSB settling error for 100 kHz full-scale sine inputs. |
| Input Offset Voltage | 1 mV typ, 4 mV max (–40°C to 85°C) - ensures ≤0.5% gain error in precision transimpedance amplifiers with 1 MΩ feedback. |
| Output Swing | 0.17 V to 4.84 V at 5 V/600 Ω - delivers >96% of rail-to-rail dynamic range for 12-bit DAC output buffering. |
| Supply Current | 0.5 mA typ per amplifier at 5 V - allows dual-channel operation on <1 mA total, critical for always-on sensor nodes. |
| Common-Mode Input Range | –0.2 V to 4.3 V at 5 V - accepts signals referenced to ground, including 0–2.5 V thermistor or bridge outputs. |
Pinout & Package
LMV822DRE4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch and 4.9 mm × 3.9 mm body size, compatible with automated SMT assembly and IPC-7351B footprint D_8_SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 45 mA sourcing/sinking; requires local 100 nF bypass capacitor. |
| 2 | IN− A | Inverting input A - high-impedance node; guard ring recommended for <10 pA bias current-sensitive designs. |
| 3 | IN+ A | Non-inverting input A - accepts DC-coupled signals from 0 V to VCC; matched trace length advised vs. Pin 2. |
| 4 | GND / VCC− | Ground reference and negative supply - shared return path; separate AGND plane recommended for mixed-signal systems. |
| 5 | VCC+ | Positive supply - decouple with 100 nF ceramic + 1 μF tantalum; avoid daisy-chaining with other ICs. |
| 6 | IN+ B | Non-inverting input B - electrically isolated from Channel A; usable for differential pair or independent signal paths. |
| 7 | IN− B | Inverting input B - identical electrical specs to Pin 2; routing symmetry improves channel matching. |
| 8 | OUT B | Amplifier B output - independent output stage; supports split-load configurations without cross-talk degradation. |
Key Features
| Feature | Design Value |
|---|---|

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 | Identical electrical specs and SOIC-8 packaging; same marking "MV822" and temperature range (–40°C to 85°C). | No functional difference; LMV822DRE4 is the RoHS-compliant, green-processed variant of LMV822DR. | Select LMV822DRE4 when RoHS compliance and lead-free soldering are required; otherwise LMV822DR is functionally interchangeable. |
| TLV2462IDR | Higher 6.4 MHz GBW and 1.6 V/μs slew rate; 0.65 mA supply current; wider input common-mode range (to VCC+). | Better suited for higher-frequency sensor interfaces (e.g., ultrasonic time-of-flight), but consumes 30% more quiescent current. | Choose TLV2462IDR only if bandwidth >5.5 MHz is mandatory and power budget allows +0.15 mA per channel. |
Compared with LMV822DR, LMV822DRE4 offers identical performance with RoHS compliance; versus TLV2462IDR, it trades 0.9 MHz bandwidth and 0.3 V/μs slew for 0.15 mA lower supply current and proven stability with 22 pF capacitive loads.

FAQ
What is the operating temperature range for LMV822DRE4?
The LMV822DRE4 is specified for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in environments such as factory automation equipment, automotive cabin modules, and outdoor IoT sensor enclosures without thermal derating of key parameters like gain bandwidth or output drive capability.
Does LMV822DRE4 support true rail-to-rail input?
LMV822DRE4 supports rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends from –0.2 V to VCC+ – 0.3 V (e.g., –0.2 V to 4.7 V at 5 V supply), which includes ground but does not reach the positive rail. For true rail-to-rail input, consider TI's TLV2462 or OPA333 families.
What is the maximum capacitive load LMV822DRE4 can drive stably?
LMV822DRE4 maintains ≥60° phase margin with up to 22 pF capacitive load when configured for 40-dB closed-loop gain and using a 2 kΩ series resistor between output and load. Driving larger capacitive loads (e.g., >100 pF) requires isolation resistance or a dedicated buffer stage to prevent peaking or oscillation.
Is LMV822DRE4 pin-compatible with LMV822DGKR?
No, LMV822DRE4 (SOIC-8) is not pin-compatible with LMV822DGKR (VSSOP-8). While both contain identical dual op-amp circuitry and share the same electrical specifications, their footprints differ: SOIC-8 has 1.27 mm pitch and 4.9 mm width, whereas VSSOP-8 has 0.65 mm pitch and 3.0 mm width. PCB layout redesign is required for substitution.
What does the "E4" suffix indicate in LMV822DRE4?
The "E4" suffix in LMV822DRE4 denotes Texas Instruments' green, lead-free, RoHS-compliant packaging with NiPdAu lead finish and halogen-free molding compound. It replaces legacy "DR" variants in new designs where environmental compliance and Pb-free soldering processes are mandated.
