STMicroelectronics TSV6293IST

Overview

TSV6293IST from STMicroelectronics is a dual micropower rail-to-rail input/output operational amplifier in MiniSO-10 package, delivering 1.3 MHz gain bandwidth at 29 µA supply current per amplifier, with shutdown control (SHDN1/SHDN2), ±4 V/V minimum stable gain, and operation down to 1.5 V supply-ideal for low-voltage sensor signal conditioning in portable medical devices.

For engineers reviewing the TSV6293IST datasheet, TSV6293IST pinout, TSV6293IST application, or TSV6293IST equivalent, key selection factors include its dual-channel shutdown capability, 800 µV max input offset voltage (A-version), EMI-hardened architecture, and guaranteed stability only above gain +4 or –3-critical for battery-powered active filtering and precision analog front-ends.

Technical Context

The TSV6293IST integrates two independent CMOS op-amps with complementary PMOS/NMOS input stages enabling true rail-to-rail input (VCC− −0.1 V to VCC+ +0.1 V) and output swing within 35 mV of rails under 10 kΩ load. Its internal current-starved compensation ensures 1.3 MHz GBP while maintaining stability only at gains ≥+4 (non-inverting) or ≤−3 (inverting), verified across −40°C to +125°C.

Each amplifier features dedicated SHDN pins (Pin 5 & Pin 6) that reduce total supply current to 5 nA typ when pulled low, placing outputs in high-impedance state; turn-on/off times are 200 ns and 20 ns respectively at 5 V, with VIH = 2 V and VIL = 0.8 V logic thresholds-enabling precise power-gating in multi-stage analog chains.

Key Specifications

Pinout & Package

FAQ

What is the minimum stable gain configuration for TSV6293IST?

The TSV6293IST is not unity-gain stable and requires a minimum closed-loop gain of +4 in non-inverting configuration or −3 in inverting configuration to ensure ≥60° phase margin. This is verified with 100 pF capacitive load and 10 kΩ resistive load per STMicroelectronics Doc ID 16882 Rev 2 Section 4.6.

Can TSV6293IST operate from a 1.5 V supply?

Yes-TSV6293IST is fully specified from 1.5 V to 5.5 V supply. At 1.5 V, it maintains 1.1 MHz GBP, 0.33 V/µs slew rate, and rail-to-rail I/O performance, with supply current dropping to 25 µA per amplifier, making it ideal for single alkaline or zinc-air battery systems.

How does the shutdown function affect output state?

When SHDN1 or SHDN2 is pulled low (≤0.8 V), the corresponding amplifier output enters high-impedance state-neither sourcing nor sinking current. Output leakage is limited to 1 nA max at 125°C, preventing unintended loading of downstream circuitry such as ADC input networks or multiplexer channels.

Is TSV6293IST suitable for driving capacitive loads?

TSV6293IST is optimized for resistive loads ≥5 kΩ; driving capacitive loads >100 pF directly may cause peaking or oscillation. For capacitive loads, add a 10–100 Ω isolation resistor in series with the output, or use the unity-gain stable TSV6393IST if bandwidth permits-per ST application note guidelines in Section 4.6.
