UMW TSV6392IDT

Overview

TSV6392IDT 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-grade), 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 TSV6392IDT datasheet, TSV6392IDT pinout, TSV6392IDT application, or TSV6392IDT equivalent, key selection criteria include its guaranteed stability at gain ≥ 4 (non-inverting) or ≥ –3 (inverting), EMI-hardened performance (EMIRR up to 92 dB at 1.8 GHz), and extended –40 °C to 125 °C operation - critical for wearable health monitors, industrial sensor nodes, and low-power data acquisition front-ends.

Technical Context

The TSV6392IDT 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 and minimal CMR degradation near rail transitions. Its internal trimming ensures ±17% spread on supply current, directly tightening dispersion of GBP (2.4 MHz typ), slew rate (1.1 V/µs), and large-signal gain (98 dB min).

It is not unity-gain stable and requires minimum closed-loop gain of –3 (inverting) or +4 (non-inverting) for stability with 100 pF load; shutdown control is TTL/CMOS-compatible (V_IL ≤ 0.8 V, V_IH ≥ 2 V at 5 V), with 200 ns turn-on and 20 ns turn-off times into 2 kΩ load.

FAQ

Is the TSV6392IDT unity-gain stable?

No. The TSV6392IDT requires minimum closed-loop gain of –3 (inverting configuration) or +4 (non-inverting) for stability with 100 pF capacitive load. For unity-gain applications, ST recommends the TSV63x family (880 kHz GBP, unity-gain stable) or TSV629x (1.3 MHz GBP). Stability is verified per Figure 5–7 in DS6635 Rev 4.

What is the maximum capacitive load the TSV6392IDT can drive without oscillation?

When configured with gain ≥ +4 (non-inverting) or ≥ –3 (inverting), the TSV6392IDT remains stable with up to 100 pF load capacitance, as confirmed in datasheet Figures 5–7. Driving >100 pF requires external isolation resistor (≥200 Ω) between output and load to maintain phase margin ≥60°.

Does the SHDN pin require pull-up/pull-down resistors?

Yes. The SHDN pin must never be left floating. It should be actively driven to V_CC+ (≥2 V at 5 V supply) to enable or to V_CC– (GND) to disable. If controlled by an open-drain GPIO, a 10–100 kΩ pull-up to V_CC+ is required; no pull-down is needed when driven low actively.

How does the TSV6392IDT perform at 1.5 V supply?

At 1.5 V, the TSV6392IDT maintains full rail-to-rail input/output swing, 2 MHz GBP, and 60 µA supply current (typ), with 35 mV output saturation voltage into 10 kΩ. Key specs like V_os, CMRR, and SR are characterized and guaranteed across the full 1.5–5.5 V range per Tables 3–6 in DS6635 Rev 4.
