UMW TSV6392AIDT

Overview

TSV6392AIDT from STMicroelectronics is a dual rail-to-rail input/output micropower CMOS operational amplifier optimized for low-voltage, battery-powered systems. It delivers 2.4 MHz gain bandwidth at just 60 µA supply current (5 V), supports 1.5–5.5 V operation, and features 800 µV max offset voltage (A-grade), 1 pA typical input bias current, and 4 kV HBM ESD rating - enabling precision sensor interfacing in portable medical and industrial instrumentation.

For engineers reviewing the TSV6392AIDT datasheet, TSV6392AIDT pinout, TSV6392AIDT application, or TSV6392AIDT equivalent, key selection criteria include its guaranteed stability at gain ≥4 (non-inverting) or ≥−3 (inverting), ultra-low shutdown current (5 nA typ), extended −40 °C to 125 °C operating range, and EMI-hardened performance up to 2.4 GHz.

Technical Context

The TSV6392AIDT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input (V_ICM = V_CC− − 0.1 V to V_CC+ + 0.1 V) and output swing within 35 mV of both rails under 10 kΩ load. Its internal trimming ensures tight ICC dispersion (±17% at 60 µA), directly stabilizing GBP (2.4 MHz), slew rate (1.1 V/µs), and large-signal gain (98 dB).

It integrates a dedicated SHDN pin (VIH = 2 V, VIL = 0.8 V at 5 V) enabling fast turn-on (200 ns) and turn-off (20 ns) transitions while placing outputs in high-impedance state. The device is not unity-gain stable and requires minimum closed-loop gain of −3 or +4 for phase margin ≥60° with 100 pF load.

FAQ

What is the minimum recommended gain for stable operation of the TSV6392AIDT?

The TSV6392AIDT requires a minimum closed-loop gain of −3 (inverting configuration) or +4 (non-inverting configuration) to ensure ≥60° phase margin with 100 pF capacitive load. This is due to its decompensated internal architecture optimized for 2.4 MHz bandwidth at 60 µA. Unity-gain configurations will oscillate and must use the TSV63x family instead.

Does the SHDN pin require external pull-up or pull-down resistors?

No - the SHDN pin has CMOS-compatible input thresholds (VIH = 2 V, VIL = 0.8 V at 5 V) and must be driven actively to V_CC (enable) or GND (disable). Leaving it floating is strictly prohibited as it may cause partial enablement, increased current draw, or undefined output states. No external resistors are needed if driven by a GPIO or logic gate.

Can the TSV6392AIDT drive a 100 pF capacitive load directly at unity gain?

No - the TSV6392AIDT is not unity-gain stable. Driving 100 pF at gain = 1 will cause sustained oscillation. For such loads, use minimum gain of −3 (inverting) or +4 (non-inverting), or add a small isolation resistor (≥22 Ω) in series with the output. Alternatively, select the unity-gain-stable TSV632 (880 kHz, 60 µA) for low-gain, high-capacitance applications.

How does the rail-to-rail input stage behave near the supply rails?

The input stage uses complementary PMOS/NMOS pairs with transition at ~0.7 V below V_CC. Within ±0.1 V of either rail, parameters degrade slightly: CMRR drops ~5 dB, V_IO increases up to 200 µV, and THD rises. However, the device guarantees no phase reversal - output remains monotonic even when inputs exceed rails by 0.1 V, critical for fault-tolerant sensor interfaces.
