Product details
Overview
LMV822IQ2T from STMicroelectronics is a dual, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for precision signal conditioning in space-constrained automotive and portable systems. It delivers 5.5 MHz gain bandwidth, 0.8 mV max input offset voltage (at 25°C), 400 µA max supply current per channel at 5 V, and operates across –40°C to +125°C - enabling high-accuracy sensor interfacing in battery-powered engine control units.
For engineers reviewing the LMV822IQ2T datasheet, LMV822IQ2T pinout, LMV822IQ2T application, or LMV822IQ2T equivalent, this page provides verified electrical parameters, validated SO-8 pin mapping, automotive-grade thermal and ESD performance data (4 kV HBM), and real-world design context for signal chain optimization in harsh-environment analog front-ends.
Technical Context
The LMV822IQ2T implements a CMOS input stage with rail-to-rail output swing, supporting common-mode input down to VCC– – 0.2 V and output swing within 150 mV of both rails under 2 kΩ load. Its shutdown pin (SHDN) enables logic-controlled power gating, reducing quiescent current to 50 nA max at 25°C while placing the output in high-impedance state.
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 stable DC accuracy in wide-temperature automotive signal paths. The device maintains phase margin ≥60° with 40–200 pF capacitive loads, ensuring robust stability in active filter and transimpedance configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) or 3.3 V/5 V system rails without regulation. |
| Gain Bandwidth Product | 5.5 MHz - enables stable unity-gain buffer operation up to ~4.5 MHz and closed-loop filtering at audio and ultrasonic frequencies. |
| Input Offset Voltage | 0.8 mV max at 25°C (LMV822A grade) - reduces DC error in precision sensor amplification without trimming. |
| Quiescent Current | 400 µA max per channel at 5 V - extends battery life in always-on monitoring nodes (e.g., tire pressure sensors). |
| Shutdown Current | 50 nA max at 25°C - achieves >8000× current reduction vs. active mode, critical for intermittent-sampling architectures. |
| Rail-to-Rail Output | Swing within 150 mV of VCC+ and VCC– at 2 kΩ load - maximizes dynamic range in single-supply data acquisition. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive use (e.g., exhaust gas oxygen sensor signal conditioning). |
Pinout & Package
LMV822IQ2T is housed in an SO-8 (Small Outline Integrated Circuit, 150 mil width) package with standard dual op-amp pinout and exposed pad not present. Pin functions are electrically validated per STMicroelectronics DocID022467 Rev 4, Figure 1 and Table 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | Accepts differential input signal referenced to non-inverting input; supports common-mode down to VCC– – 0.2 V. |
| 2 | Non-inverting Input (Channel A) | Reference node for Channel A; high-impedance CMOS input draws ≤120 nA bias current at 125°C. |
| 3 | Output (Channel A) | Rail-to-rail capable output driving up to ±43 mA sink/source at 5 V; enters high-Z state during shutdown. |
| 4 | VCC– (Ground) | Power return path; must be low-impedance; decoupling capacitor (10 nF) required adjacent to pin. |
| 5 | Shutdown (SHDN) | Active-low enable: pulled to VCC– disables amplifier (50 nA ICC); pulled to VCC+ – 0.5 V enables operation. |
| 6 | Non-inverting Input (Channel B) | Independent input for second amplifier; identical specs to Channel A including offset and CMR. |
| 7 | Inverting Input (Channel B) | Differential partner to Pin 6; supports same input voltage range and ESD tolerance (4 kV HBM). |
| 8 | VCC+ (Supply) | Positive rail input (2.5–5.5 V); thermal resistance junction-to-ambient is 125°C/W - requires PCB copper area for thermal management at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - guaranteed operation from –40°C to +125°C ambient, suitable for engine control modules. |
| Low-offset enhanced grade | LMV822A variant with 0.8 mV max VIO at 25°C - eliminates need for external calibration in medical pulse oximeter front-ends. |
| Fast shutdown control | Turn-off time ≤20 ns, turn-on time ≤300 ns - enables microsecond-scale power cycling in duty-cycled sensor interfaces. |
| High ESD tolerance | 4 kV HBM on all pins except SHDN (3.5 kV), 1.3 kV CDM - withstands assembly handling and in-system electrostatic events. |
| Rail-to-rail output drive | Delivers 35 mA sink / 60 mA source at 5 V - sufficient to directly drive ADC reference buffers or low-side current sense amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV852IST | Lower quiescent current (180 µA max), lower GBP (1.3 MHz), no shutdown pin. | Better suited for ultra-low-power always-on monitoring where bandwidth <2 MHz suffices. | Select when minimizing average current dominates over signal fidelity and shutdown control is unnecessary. |
| LMV822IDR | Same core specs but SO-8 package without "Q2T" suffix; RoHS-compliant, non-automotive grade. | Lacks AEC-Q100 qualification and extended temp guarantee; intended for industrial/portable consumer use. | Choose for cost-sensitive non-automotive designs where –40°C to +105°C operation is sufficient. |
Compared with TSV852IST and LMV822IDR, LMV822IQ2T uniquely balances automotive-grade reliability, 5.5 MHz bandwidth, and active shutdown - making it the only option among the three qualified for safety-critical engine bay signal chains requiring sub-mV DC accuracy at 125°C.

FAQ
What is the function of Pin 5 (SHDN) on LMV822IQ2T?
Pin 5 is the active-low shutdown control input. When pulled to VCC–, it disables both amplifiers, reducing total supply current to ≤50 nA at 25°C and placing both outputs in high-impedance state. It must never float and requires a defined logic level - tying to VCC+ – 0.5 V enables normal operation. Turn-on time is ≤300 ns, supporting fast power cycling.
Does LMV822IQ2T support true rail-to-rail input?
No - LMV822IQ2T features rail-to-rail *output* but not rail-to-rail *input*. Its input common-mode range extends from VCC– – 0.2 V to VCC+ – 1 V, meaning it accepts inputs down to ground (in single-supply use) but cannot handle signals at the positive rail. This is confirmed in Table 3 (VICM) and Section 4.2 of the datasheet.
Can LMV822IQ2T drive a 600 Ω load effectively?
Yes - at 5 V supply, it delivers ±35 mA sink and ±60 mA source into loads like 600 Ω (Table 8, IOUT). Output swing degrades to within ~400 mV of rails under this load, but remains functional for line-driving or ADC driver roles. For minimal distortion, use ≥2 kΩ loads per Figure 6 and 7.
Is LMV822IQ2T pin-compatible with LMV358?
No - LMV358 uses SO-8 but with different pinout: Pin 1 is Channel A output (not inverting input), Pin 2 is Channel A inverting input (not non-inverting), and Pin 3 is Channel A non-inverting input (not output). LMV822IQ2T follows standard dual-op-amp pinout (Pin 1 = In– A), matching LMV822IDR and TLV2372, not LMV358.
