STMicroelectronics LMV824IYPT

Overview

LMV824IYPT from STMicroelectronics is a quad, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for precision signal conditioning in automotive and portable 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 across –40°C to +125°C. It is used in battery-powered sensor front-ends requiring stable DC accuracy and fast turn-on/turn-off control.

For engineers reviewing the LMV824IYPT datasheet, LMV824IYPT pinout, LMV824IYPT application, or LMV824IYPT equivalent, this page provides verified electrical specifications, TSSOP14 package layout, automotive-grade thermal and ESD performance (4 kV HBM), shutdown timing (300 ns turn-on), and real-world use cases in medical instrumentation and active filtering circuits.

Technical Context

The LMV824IYPT integrates four independent op-amps in a single TSSOP14 package, each featuring rail-to-rail output swing (±150 mV from rails into 2 kΩ), input common-mode range extending to V_CC– – 0.2 V, and a dedicated SHDN pin enabling per-amplifier power gating. Its 5.5 MHz GBP and 1.4–1.9 V/µs slew rate support medium-speed closed-loop configurations without stability compromise up to 200 pF load capacitance.

It implements a shutdown mode reducing total quiescent current to ≤50 nA (25°C) while placing outputs in high-impedance state - critical for multiplexed analog front-ends. Input offset drift is tightly controlled at 1 µV/°C over –40°C to +125°C, and CMRR reaches 90 dB (typ.) at 5 V supply, ensuring robustness against supply and common-mode noise in harsh environments.

FAQ

What is the maximum capacitive load the LMV824IYPT can drive without instability?

The LMV824IYPT remains stable driving up to 200 pF with a 10 kΩ load in unity-gain follower configuration, as confirmed by phase margin measurements ≥60° across temperature and supply voltage. For loads >100 pF, a 10 Ω series resistor at the output is recommended to isolate capacitive reactance from the internal compensation network.

Can the SHDN pin be driven directly by a 3.3 V GPIO from an MCU operating at 3.3 V supply?

Yes - the SHDN pin accepts VIH ≥ V_CC+ – 0.5 V and VIL ≤ 0.5 V. When V_CC+ = 5 V, VIH ≥ 4.5 V is required; however, with V_CC+ = 3.3 V, VIH ≥ 2.8 V is sufficient, making direct interface with standard 3.3 V logic safe and reliable without level shifting.

How does the input offset voltage change over temperature, and is it specified for the full –40°C to +125°C range?

Input offset voltage is guaranteed ≤2 mV over –40°C to +125°C for the LMV824A variant (enhanced accuracy grade). The drift coefficient is 1 µV/°C max, meaning worst-case ΔV_OS from 25°C to 125°C is ≤100 µV - significantly less than the 2 mV absolute limit, ensuring predictable performance in thermal cycling environments.

Is the exposed pad on the TSSOP14 package electrically connected, and how should it be handled in PCB layout?

The exposed pad is internally connected to V_CC– (pin 4) and must be soldered to a PCB copper pour tied to the system ground plane. This connection reduces thermal resistance (R_thJA = 100°C/W vs. 205°C/W for SC70-5), improves power dissipation, and enhances EMI immunity - leaving it unconnected degrades thermal performance and may cause instability under load.
