Product details
Overview
TSV6292AIST from STMicroelectronics is a dual micropower CMOS operational amplifier with rail-to-rail input and output, 1.3 MHz gain bandwidth product, 29 µA typical supply current per amplifier, and operation down to 1.5 V supply. It delivers 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and is specified for -40°C to +125°C operation in MiniSO-8 package - ideal for low-voltage sensor signal conditioning in portable medical devices.
For engineers reviewing the TSV6292AIST datasheet, TSV6292AIST pinout, TSV6292AIST application, or TSV6292AIST equivalent, key selection criteria include guaranteed stability at gain ≥ +4, EMI-hardened performance (92 dB EMIRR at 1.8 GHz), shutdown capability (5 nA typ), and rail-to-rail operation across 1.5–5.5 V supplies - critical for battery-powered analog front-ends.
Technical Context
The TSV6292AIST employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (≤35 mV from rails into 10 kΩ). Its internal compensation ensures stability only at closed-loop gains ≥ +4 (non-inverting) or ≤ −3 (inverting), with phase margin ≥60° under specified load conditions (RL = 10 kΩ, CL = 20 pF).
It features ultra-low input bias current (1 pA typ), low offset drift (2 µV/°C), and high EMI rejection (up to 92 dB at 1.8 GHz), achieved via proprietary layout hardening - making it suitable for high-impedance sensor interfaces where DC accuracy and RF immunity are co-critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V - enables direct use with single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz typ - supports bandwidths up to ~300 kHz in unity-gain-stable configurations when used at minimum stable gain (+4), sufficient for ECG, pulse oximetry, and active filter stages. |
| Input Offset Voltage | 800 µV max (A version) - ensures <0.5% error in 100 mV full-scale sensor outputs without trimming, critical for precision biopotential amplification. |
| Supply Current per Amp | 29 µA typ / 36 µA max - enables >1-year battery life in coin-cell-powered devices operating at 1–10 Hz sampling rates. |
| Input Bias Current | 1 pA typ - preserves signal integrity from high-impedance sources (e.g., pH electrodes, piezoresistive sensors >100 MΩ). |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in wearable medical electronics without external filtering. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors and industrial field transmitters requiring extended thermal robustness. |
Pinout & Package
TSV6292AIST is housed in an 8-pin MiniSO-8 package (ECOPACK® compliant, 3.0 × 3.0 mm body, 0.65 mm pitch), optimized for space-constrained PCB layouts in portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Rail-to-rail capable output stage; sinks/supplies ≥40 mA at 5 V; remains functional down to 1.5 V supply. |
| 2 (−IN1) | Inverting input of Amp 1 | High-impedance node (1 pA bias); part of complementary input pair enabling rail-to-rail common-mode range. |
| 3 (+IN1) | Non-inverting input of Amp 1 | Same high-Z, rail-to-rail input structure as Pin 2; differential pair transition occurs near VCC+ −0.7 V. |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; supports true 0 V input common-mode down to −0.1 V relative to this pin. |
| 5 (+IN2) | Non-inverting input of Amp 2 | Independent high-Z input; electrically isolated from Amp 1 inputs - enables dual-channel sensor buffering without crosstalk. |
| 6 (−IN2) | Inverting input of Amp 2 | Matches Pin 2 performance; allows differential sensing or independent signal paths in compact footprint. |
| 7 (OUT2) | Amplifier 2 output | Identical rail-to-rail output behavior to Pin 1; supports simultaneous dual-channel signal processing in one IC. |
| 8 (VCC+) | Positive supply rail | Accepts 1.5–5.5 V; internal regulation ensures stable biasing across full voltage range and temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3 V ADC interface) without level-shifting circuitry. |
| Micropower operation (29 µA) | Reduces quiescent power to 87 nW per amplifier at 3 V - essential for always-on biosensor nodes powered by CR2032 cells. |
| EMI-hardened architecture | Integrates on-die filtering and layout techniques to maintain DC accuracy and AC response in noisy RF environments (e.g., Bluetooth/Wi-Fi coexistence). |
| Extended temperature range | Guarantees parametric performance from −40°C to +125°C - validated for use in automotive cabin sensors and industrial process controllers. |
| Low input offset drift | 2 µV/°C max ensures <20 µV total offset shift over full temperature range - eliminates need for periodic recalibration in field-deployed equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV622IST | 420 kHz GBP, unity-gain stable, 29 µA ICC - lower bandwidth but stable at G = 1. | Suitable for unity-gain buffers or low-frequency (<100 kHz) applications where stability at G = 1 is mandatory. | Select when gain configuration flexibility is limited and G = 1 operation is required; trade-off is bandwidth reduction by 70%. |
| TSV6392IST | 2.4 MHz GBP, 60 µA ICC, rail-to-rail I/O - higher speed and power, stable at G ≥ +11. | Better for active filters or higher-speed sensor interfaces (e.g., ultrasonic transducers) requiring >1 MHz closed-loop bandwidth. | Choose when bandwidth >1 MHz is needed and 2× higher supply current is acceptable; requires higher minimum gain for stability. |
Compared with TSV6292AIST, TSV622IST trades bandwidth for unconditional unity-gain stability, while TSV6392IST doubles bandwidth at double the current and stricter gain requirements - making TSV6292AIST the optimal balance for precision, low-power, medium-bandwidth dual-channel signal chains.

FAQ
Is TSV6292AIST unity-gain stable?
No. The TSV6292AIST is not unity-gain stable and requires a minimum closed-loop gain of +4 (non-inverting) or −3 (inverting) to ensure phase margin ≥60°. This is confirmed in Table 4 and Section 4.6 of the datasheet, which specifies stability conditions for RL = 10 kΩ and CL = 20 pF. For unity-gain applications, consider the TSV622IST instead.
What is the maximum capacitive load the TSV6292AIST can drive?
The TSV6292AIST is characterized for stability with up to 100 pF capacitive load when used at minimum stable gain (+4) and RL = 10 kΩ. Driving larger capacitive loads (e.g., >200 pF) risks peaking or oscillation unless isolation resistance (≥10 Ω) is added in series with the output, as recommended in Section 4.6 for capacitive load driving.
Does TSV6292AIST have a shutdown pin?
No. The TSV6292AIST does not include a shutdown function. Shutdown capability is only present in the TSV6293A (dual with two SHDN pins) and TSV6295A (quad with four SHDN pins) variants. The TSV6292AIST operates continuously when powered and draws 29 µA per amplifier regardless of signal activity.
Can TSV6292AIST operate from a 1.5 V supply?
Yes. The TSV6292AIST is fully specified and guaranteed to operate from 1.5 V to 5.5 V, with all key parameters (GBP, Vio, ICC, SR) characterized at 1.5 V, 1.8 V, 3.3 V, and 5 V. Figure 2 in the datasheet confirms stable supply current down to 1.5 V, and rail-to-rail input/output functionality is maintained across this entire range.
