STMicroelectronics TSV6392ID

Overview

TSV6392ID from STMicroelectronics is a dual rail-to-rail input/output micropower operational amplifier optimized for low-voltage, battery-powered systems. It delivers 2.4 MHz gain bandwidth at just 60 µA supply current per channel (5 V), operates from 1.5 V to 5.5 V, features 800 µV max offset voltage (A version), and supports shutdown mode with 5 nA typical quiescent current - enabling precision signal conditioning in portable medical sensors and active filtering stages.

For engineers reviewing the TSV6392ID datasheet, TSV6392ID pinout, TSV6392ID application, or TSV6392ID equivalent, key selection criteria include its guaranteed stability at gain ≥ 4 (non-inverting) or ≥ –3 (inverting), EMI-hardened architecture (EMIRR up to 92 dB at 1.8 GHz), rail-to-rail output swing within 35 mV of rails (10 kΩ load), and extended industrial temperature range (–40 °C to 125 °C).

Technical Context

The TSV6392ID employs complementary PMOS/NMOS input pairs to achieve true rail-to-rail input operation across (V_CC–) – 0.1 V to (V_CC+) + 0.1 V, with no phase reversal. Its internal current-source compensation ensures stable 2.4 MHz GBP while maintaining 1.1 V/µs slew rate and < 2 µV/°C offset drift - critical for DC-coupled sensor front-ends.

Shutdown control is implemented via a dedicated SHDN pin (VIH = 2 V min at 5 V, VIL = 0.8 V max), driving output to high-impedance state with 200 ns turn-on and 20 ns turn-off times. The device's 4 kV HBM ESD rating and 61–92 dB EMIRR across 400 MHz–2.4 GHz support robust operation in noisy portable environments.

FAQ

What is the minimum stable gain configuration for TSV6392ID?

The TSV6392ID is not unity-gain stable and requires minimum closed-loop gain of 4 (non-inverting) or –3 (inverting) for unconditional stability with 100 pF capacitive load, as verified by phase margin ≥60° testing per DS6635 §5.6. Using lower gains risks oscillation and must be avoided unless external compensation is applied.

Does TSV6392ID support true single-supply operation down to 1.5 V?

Yes - the TSV6392ID operates fully specified from 1.5 V to 5.5 V, with rail-to-rail input extending from (V–) – 0.1 V to (V+) + 0.1 V and output swing within 35 mV of both rails under 10 kΩ load, enabling direct interface with 1.8 V or 3.3 V ADCs without level-shifting circuitry.

How does the shutdown function affect output state and timing?

When SHDN is pulled low (≤0.8 V at 5 V supply), the amplifier outputs enter high-impedance state with ≤1 nA leakage current; turn-off completes in 20 ns and turn-on requires 200 ns to settle within 200 mV of final value, as measured with 2 kΩ load per DS6635 §4 and §5.4.

Is TSV6392ID compatible with standard SOT23-8 PCB footprints?

Yes - the TSV6392ID uses JEDEC-standard SOT23-8 package (2.8 × 2.6 mm body, 0.65 mm lead pitch) with mechanical dimensions matching MS-012AA specification; recommended footprint matches Figure 30 in DS6635, including 0.40 mm pad width and 1.20 mm pad length for reliable reflow soldering.
