Product details
Overview
LMV824AIDT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for low-power, high-accuracy signal conditioning in 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. Used in battery-powered sensor front-ends and automotive cabin control modules.
For engineers reviewing the LMV824AIDT datasheet, LMV824AIDT pinout, LMV824AIDT application, or LMV824AIDT equivalent, key selection criteria include shutdown current (≤50 nA), rail-to-rail output swing (±150 mV from rails @ 2 kΩ), input offset drift (1 µV/°C), and AEC-Q100 qualification for automotive use.
Technical Context
The LMV824AIDT integrates four independent amplifiers with individual shutdown control per channel, enabling dynamic power management in multi-sensor systems. Its input stage supports common-mode voltage down to VCC– – 0.2 V and up to VCC+ – 1 V, eliminating phase reversal under rail-adjacent inputs.
It features a unity-gain-stable architecture with 60° phase margin and 10 dB gain margin, optimized for driving capacitive loads up to 200 pF. The shutdown function asserts high-impedance output and reduces total quiescent current to ≤50 nA at 25°C, with turn-on/turn-off times of 300 ns / 20 ns respectively.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854IQ4T | Lower supply current (180 µA max per channel), no shutdown pin per channel - single global shutdown only. | Optimized for ultra-low-power always-on sensing; lacks per-channel power gating for burst-mode systems. | Select when total system current is critical and channel-level shutdown is unnecessary. |
| LMV844QDGKR | Same pinout and specs, but AEC-Q100 Grade 0 (–40°C to +150°C) and higher ESD (6 kV HBM). | Targeted for under-hood engine control modules requiring extended junction temperature margin. | Select for applications exceeding +125°C ambient or demanding higher robustness in harsh ESD environments. |
Compared with TSV854IQ4T and LMV844QDGKR, the LMV824AIDT uniquely balances per-channel shutdown control, 5.5 MHz bandwidth, and AEC-Q100 Grade 1 qualification - making it optimal for cost-sensitive, multi-sensor automotive cabin systems where independent channel power management is required.

FAQ
What is the maximum capacitive load the LMV824AIDT can drive while maintaining stability?
The LMV824AIDT is characterized for stable operation with capacitive loads up to 200 pF when configured as a unity-gain follower, as verified by phase margin ≥60° across –40°C to +125°C. For loads >100 pF, ST recommends adding a 10 Ω series resistor between output and capacitor to isolate reactive feedback.
How does the shutdown pin behave electrically, and what are the voltage thresholds?
The SHDN pin is active-low with VIH = VCC+ – 0.5 V (min) and VIL = 0.5 V (max). Pulling SHDN to VCC– places the corresponding amplifier in shutdown, reducing supply current to ≤50 nA and forcing output into high-impedance state. The pin must never float and requires explicit logic-level drive.
Can the LMV824AIDT operate from a 2.5 V single supply with rail-to-rail input and output?
Yes - it supports 2.5 V to 5.5 V single-supply operation. Input common-mode range extends from VCC– – 0.2 V to VCC+ – 1 V (enabling ground-referenced inputs), and output swings within 150 mV of both rails under 2 kΩ load, delivering full dynamic range in low-voltage systems.
Is the LMV824AIDT pin-compatible with the standard LMV824 without shutdown?
No - LMV824AIDT uses TSSOP14 with four dedicated SHDN pins (Pins 5, 9, 14, and an unassigned pin), whereas LMV824 uses SO14 or TSSOP14 without shutdown functionality. The pinouts differ fundamentally; PCB layout and schematic must be redesigned for LMV824AIDT integration.
