Product details
Overview
LMV822IDRE4 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 and battery-powered analog front-ends.
For engineers reviewing the LMV822IDRE4 datasheet, LMV822IDRE4 pinout, LMV822IDRE4 application, or LMV822IDRE4 equivalent, key selection criteria include its rail-to-rail output swing down to 100 mV from rails at 2 kΩ load, input common-mode range extending to ground, and guaranteed performance over extended temperature for automotive and industrial sensing interfaces.
Technical Context
The LMV822IDRE4 implements a complementary input stage enabling rail-to-rail input common-mode operation down to ground and up to VCC–0.2 V. Its output stage uses Class AB architecture to achieve rail-to-rail swing with 20 mA sourcing/sinking capability at 5 V.
It features no crossover distortion and maintains stable unity-gain operation with 64.2° phase margin at 5 V with 600 Ω load, supporting direct drive of resistive and moderate capacitive loads without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable closed-loop gain ≥10 at 500 kHz for anti-aliasing or active filtering. |
| Slew Rate | 1.9 V/μs typ at 5 V - supports 1 Vpp signals up to ~300 kHz without distortion in unity-gain buffer configurations. |
| Input Offset Voltage | 3.5 mV max (–40°C to 125°C) - ensures ≤1.75 mV error in 500 mV full-scale 12-bit ADC interface. |
| Output Swing (RL = 2 kΩ) | 0.1 V to 4.9 V at 5 V supply - delivers >98% rail utilization for maximizing dynamic range in low-voltage data acquisition. |
| Supply Current per Amplifier | 0.7 mA max (–40°C to 125°C) - enables dual-channel amplification in sub-1.5 mA total system analog signal chain budget. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive sensors and industrial motor control feedback circuits. |
Pinout & Package
LMV822IDRE4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.91 mm × 4.90 mm body size, and exposed pad not present. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives loads up to 20 mA; rail-to-rail swing enables direct interfacing with SAR ADC references. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node (IIB = 150 nA max); requires matched trace routing for precision differential gain. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts signals from 0 V to VCC–0.2 V; supports ground-referenced sensor outputs. |
| 4 | GND/VCC− | Power return and negative supply reference - must connect to low-impedance ground plane; shared with second amplifier's return path. |
| 5 | VCC+ | Positive supply input - decoupling capacitor (0.1 μF ceramic) required within 5 mm for stability at high frequencies. |
| 6 | 2IN+ | Non-inverting input of Amplifier B - independent of Amplifier A; enables dual-channel signal conditioning on one die. |
| 7 | 2IN− | Inverting input of Amplifier B - electrically isolated from Amplifier A inputs; supports separate feedback networks. |
| 8 | 2OUT | Amplifier B output - identical AC/DC specs to Pin 1; allows simultaneous processing of two analog channels. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates 2nd-harmonic artifacts in audio and precision waveform generation below 100 kHz. |

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 (550 μA/amp typ), wider input voltage range (rail-to-rail in), same SOIC-8 package. | Preferred where input rail-to-rail is mandatory (e.g., high-side current sensing), but less optimal for ultra-low-power designs. | Select TLV2462IDR when input common-mode range beyond LMV822IDRE4's –0.2 V to VCC–0.2 V is required. |
| OPA2316IDR | Higher GBW (10 MHz), lower noise (11 nV/√Hz), higher supply current (0.8 mA/amp typ), same SOIC-8 footprint. | Better suited for higher-frequency sensor interfaces (e.g., ultrasonic transducers) where speed and noise dominate over power. | Choose OPA2316IDR when system-level bandwidth >1 MHz or input-referred noise <20 nV/√Hz is critical. |
Compared with TLV2462IDR and OPA2316IDR, LMV822IDRE4 offers the lowest quiescent current among these three while maintaining sufficient bandwidth for DC–500 kHz signal chains, making it optimal for thermistor, strain gauge, and low-speed current sensing where power efficiency is prioritized.

FAQ
What is the maximum operating temperature of the LMV822IDRE4?
The LMV822IDRE4 is characterized for operation 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 LMV822IDRE4 suitable for under-hood automotive and industrial environments where ambient temperatures exceed 85°C.
Does the LMV822IDRE4 support rail-to-rail input?
No, the LMV822IDRE4 does not support rail-to-rail input. Its input common-mode voltage range extends from –0.2 V to VCC–0.2 V (at 25°C), meaning it accepts signals down to ground but not up to VCC. This is explicitly specified in the "Electrical Characteristics" tables for both 2.7 V and 5 V operation in the LMV8xxI datasheet.
What is the typical supply current for the LMV822IDRE4 at 3.3 V?
While the datasheet specifies supply current at 2.5 V, 2.7 V, and 5 V, interpolation shows LMV822IDRE4 draws approximately 0.45 mA per amplifier at 3.3 V and 25°C. This value is derived from the ICC vs. VCC curve (Figure 3) and confirmed by the 0.45–0.6 mA range listed for LMV822 at 2.7 V and –40°C to 125°C, scaled linearly for 3.3 V operation.
Can the LMV822IDRE4 drive a 600 Ω load to rail?
No - at 600 Ω load, the LMV822IDRE4 output swing is limited to 0.17 V above GND and 4.84 V below VCC at 5 V supply (25°C). Full rail-to-rail swing is only achievable into loads ≥10 kΩ. Driving 600 Ω requires accepting ~170 mV headroom loss at both rails, as verified in the "Output Swing" specifications under RL = 600 Ω test conditions.
Is the LMV822IDRE4 pin-compatible with the LMV822DR?
Yes - LMV822IDRE4 and LMV822DR share identical SOIC-8 (D) package, pinout, and electrical functionality. The "I" suffix denotes extended temperature grade (–40°C to 125°C), while "E4" indicates RoHS-compliant lead finish; both use the same MV822I top-side marking and mechanical footprint per TI's packaging addendum.
