Product details
Overview
LMV822AIYST from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for precision signal conditioning in low-voltage, power-constrained systems. It delivers 5.5 MHz gain bandwidth, 0.8 mV max input offset voltage (25°C), 400 µA max supply current per channel at 5 V, and operates from 2.5 V to 5.5 V across –40°C to +125°C - enabling use in automotive sensor front-ends and portable medical monitors.
For engineers reviewing the LMV822AIYST datasheet, LMV822AIYST pinout, LMV822AIYST application, or LMV822AIYST equivalent, key selection considerations include its dual-channel shutdown control, rail-to-rail output swing (≤150 mV from rails @ 2 kΩ), enhanced offset accuracy versus LMV321, and AEC-Q100 qualification for automotive signal chains.
Technical Context
The LMV822AIYST implements a CMOS input stage with rail-to-rail output stage, supporting input common-mode range from VCC– – 0.2 V to VCC+ – 1 V and output swing within 150 mV of both supply rails under 2 kΩ load. Its internal shutdown logic asserts high-impedance output when SHDN is pulled to VCC–, reducing quiescent current to ≤50 nA at 25°C.
It features 1.4–1.9 V/µs slew rate (5 V supply), 70–90 dB CMRR over temperature, and 1 µV/°C max input offset drift - confirming suitability for DC-coupled, wide-temperature analog front-ends where gain stability and offset predictability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3 V logic without level shifting. |
| Gain Bandwidth Product | 5.5 MHz - supports stable unity-gain buffer operation up to ~5 MHz with ≥60° phase margin (CL ≤ 100 pF). |
| Input Offset Voltage | 0.8 mV max at 25°C - reduces DC error in precision transducer amplification without trimming. |
| Quiescent Current / Channel | 400 µA max at 5 V - extends battery life in dual-sensor monitoring nodes (e.g., ECG + temperature). |
| Shutdown Current | 50 nA max at 25°C - allows micro-power sleep mode in always-on automotive diagnostic modules. |
| Rail-to-Rail Output Swing | ≤150 mV from rails @ 2 kΩ load - maximizes dynamic range in single-supply 3.3 V data acquisition systems. |
| Operating Temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics. |
Pinout & Package
LMV822AIYST is housed in a MiniSO-8 (SO8) package - an 8-pin, surface-mount, gull-wing lead frame with 1.27 mm pitch and exposed pad for thermal enhancement. Pin 1 is marked by a dot or bevelled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low enable: tie to VCC+ for normal operation; pull to VCC– to enter 50 nA shutdown state with high-Z output. |
| 2 (IN–) | Inverting input (Channel A) | Accepts differential signals down to VCC– – 0.2 V; no phase reversal across full common-mode range. |
| 3 (IN+) | Non-inverting input (Channel A) | Supports rail-to-rail input; bias current ≤120 nA ensures low error in high-impedance sensor interfaces. |
| 4 (VCC–) | Negative supply / ground | Reference node for both channels and shutdown logic; must be low-impedance with local 10 nF decoupling. |
| 5 (OUT) | Output (Channel B) | Delivers rail-to-rail swing (≤150 mV from rails) into 2 kΩ; capable of ±43 mA sink/source at 5 V. |
| 6 (IN–) | Inverting input (Channel B) | Independent of Channel A; shares same electrical specs including 0.8 mV max VIO and 1 µV/°C drift. |
| 7 (IN+) | Non-inverting input (Channel B) | Dual-channel symmetry allows matched gain stages for differential signal processing or dual-sensor conditioning. |
| 8 (VCC+) | Positive supply | Accepts 2.5–5.5 V; internal regulation ensures stable performance across battery discharge profiles. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 qualified - validated for reliability in engine control, ADAS sensors, and body electronics. |
| Enhanced offset accuracy | 0.8 mV max VIO at 25°C (vs. 3.5 mV for standard LMV822) - reduces calibration burden in factory-set instrumentation. |
| Ultra-low shutdown current | 50 nA max at 25°C - enables >10-year shelf life in battery-backed automotive event recorders. |
| Rail-to-rail output stage | 150 mV max headroom at 2 kΩ - preserves >90% of 3.3 V ADC full-scale range in single-supply configurations. |
| Wide supply range | 2.5 V to 5.5 V operation - interoperable with 2.8 V LiFePO₄, 3.3 V MCU I/O, and 5 V legacy peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822IDR | Standard-grade (non-A) version: 3.5 mV max VIO at 25°C; same GBW, supply range, and package. | Lacks AEC-Q100 qualification and enhanced offset spec - suitable for commercial-grade portable devices only. | Select when cost sensitivity outweighs automotive qualification and sub-mV offset requirements. |
| TSV852IST | Lower power: 180 µA max ICC per channel at 5 V; 1.3 MHz GBW; same MiniSO-8 package and rail-to-rail output. | Insufficient bandwidth for >100 kHz active filtering; optimized for ultra-low-power sensor nodes, not high-fidelity signal chains. | Choose for battery life-critical applications where 5.5 MHz bandwidth is unnecessary and 1.3 MHz suffices. |
Compared with LMV822IDR, LMV822AIYST provides tighter offset and automotive qualification at modest cost premium; versus TSV852IST, it trades 2.2× higher supply current for 4.2× greater bandwidth and superior DC accuracy - making it optimal for precision, wide-temperature, medium-speed analog front-ends.

FAQ
What is the maximum output current capability of LMV822AIYST at 5 V supply?
At VCC = 5 V, LMV822AIYST delivers ±43 mA sink current and ±70 mA source current into resistive loads (per channel), with guaranteed performance across –40°C to +125°C. Output voltage swing remains within 150 mV of rails at 2 kΩ load, enabling robust interfacing with ADCs and analog switches.
Does LMV822AIYST require external compensation for unity-gain stability?
No external compensation is required: LMV822AIYST is internally compensated for unity-gain stability with ≥60° phase margin at CL ≤ 100 pF. Stability testing confirms ≥45° phase margin even with 200 pF capacitive load in follower configuration, simplifying PCB layout for sensor interface circuits.
How does the shutdown function affect output state and recovery time?
When SHDN is pulled to VCC–, output enters high-impedance state with ≤1 nA leakage current, and supply current drops to ≤50 nA. Turn-on time is ≤300 ns (to ±200 mV), and turn-off time is ≤20 ns - enabling rapid cycling in burst-mode data acquisition systems without output glitches.
Is LMV822AIYST pin-compatible with industry-standard dual op-amps like LMV358?
No - LMV822AIYST uses MiniSO-8 package with SHDN on Pin 1, whereas LMV358 (SO8) places VCC+ on Pin 8 and lacks shutdown. Direct replacement requires PCB redesign. However, LMV822AIYST matches LMV822IDR pinout exactly, allowing drop-in upgrade for enhanced accuracy and qualification.
