Product details

Overview

LMV824AIPT from STMicroelectronics is a quad, rail-to-rail output operational amplifier with shutdown capability, designed for precision signal conditioning in automotive and battery-powered 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 from 2.5 V to 5.5 V across –40°C to +125°C.

For engineers reviewing the LMV824AIPT datasheet, LMV824AIPT pinout, LMV824AIPT application, or LMV824AIPT equivalent, key selection criteria include shutdown-enabled power efficiency (50 nA max), automotive-grade temperature robustness, rail-to-rail output swing under 2 kΩ load, and guaranteed performance at 2.5 V supply for ultra-low-voltage sensor interfaces.

Technical Context

The LMV824AIPT 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 V_CC– – 0.2 V and up to V_CC+ – 1 V, eliminating phase reversal during ground-referenced sensing.

It employs a unity-gain-stable architecture with 60° phase margin and 10 dB gain margin, optimized for capacitive loads up to 200 pF. The shutdown function forces output into high-impedance state with <1 nA leakage and 300 ns turn-on time, supporting fast wake-up in duty-cycled applications.

13 (IN+ C)	Non-inverting input C	Supports common-mode voltages up to V_CC+ – 1 V, critical for high-side current sensing.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV824IPT	Higher 3.5 mV max input offset voltage (vs. 0.8 mV), no enhanced accuracy grade.	Suitable for non-critical signal paths where cost sensitivity outweighs precision requirements.	Select when budget constraints preclude A-grade offset performance but TSSOP14 footprint and shutdown functionality are mandatory.
TSV854IST	Lower 180 µA max supply current per channel, but reduced 1.3 MHz GBP and no shutdown pins.	Better for always-on ultra-low-power nodes where bandwidth <2 MHz suffices and per-channel disable is unnecessary.	Choose for extended battery life in static sensor nodes where 5.5 MHz bandwidth and independent shutdown are not required.

Compared with LMV824IPT, the LMV824AIPT provides 4.4× lower offset for precision measurement, while TSV854IST trades 77% lower quiescent current for 76% less bandwidth and loss of shutdown control-making LMV824AIPT optimal for automotive and medical applications demanding both accuracy and dynamic power management.

FAQ

What is the maximum capacitive load the LMV824AIPT can drive while maintaining stability?

The LMV824AIPT remains stable with capacitive loads up to 200 pF when configured as a unity-gain follower, as verified in Figure 11 of the datasheet. For loads exceeding 100 pF, a 10 Ω series resistor between output and load is recommended to preserve 60° phase margin across –40°C to +125°C.

Can the shutdown pins be tied together for simultaneous channel disable?

Yes, all four SHDN pins (pins 5, 9, 14, and 1) can be connected to a common control line. Doing so disables all amplifiers concurrently, reducing total supply current to ≤200 nA at 85°C. Ensure the control line is actively driven-never left floating-to prevent unintended partial activation.

Does the LMV824AIPT support true single-supply operation with input signals at ground potential?

Yes. The input common-mode range extends to V_CC– – 0.2 V, allowing direct connection of ground-referenced sensors (e.g., thermistors, bridge transducers) without level-shifting circuitry. No phase reversal occurs, and parameters remain within datasheet limits across the full –40°C to +125°C range.

How does the output voltage swing change at 2.5 V supply versus 5 V supply?

At 2.5 V supply, the LMV824AIPT delivers ±120 mV rail-to-rail swing into 2 kΩ (per Table 6), versus ±150 mV at 5 V (per Table 8). This 30 mV reduction reflects lower output stage drive strength at minimum voltage but still enables >90% of full-scale ADC utilization in 2.5 V systems.
