Product details
Overview
TSV6294AIPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for micropower, low-voltage operation. It delivers 1.3 MHz gain bandwidth at 29 µA supply current per amplifier, supports 1.5–5.5 V supply, and features 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and EMI hardening-enabling precision signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV6294AIPT datasheet, TSV6294AIPT pinout, TSV6294AIPT application, or TSV6294AIPT equivalent, key selection criteria include minimum stable gain (+4 non-inverting / –3 inverting), shutdown capability (not present on TSV6294A variant), rail-to-rail swing within 35 mV of rails, and guaranteed performance across –40°C to +125°C.
Technical Context
The TSV6294AIPT uses complementary PMOS/NMOS input stages to achieve 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 requires minimum closed-loop gain of +4 (non-inverting) or –3 (inverting) for stability with 100 pF load.
It operates across 1.5–5.5 V supply and maintains 1.3 MHz GBP, 0.5 V/µs slew rate, and 80 dB CMRR at 5 V - all while consuming only 29 µA per op-amp. The A-grade version guarantees ≤800 µV input offset voltage and 2 µV/°C drift over temperature.
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 3.3/5 V rails without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz typ - supports audio-band filtering (e.g., 20 kHz anti-aliasing) and sensor signal amplification with <1% gain error up to 100 kHz. |
| Supply Current per Op-Amp | 29 µA typ - allows four-channel operation at <116 µA total, extending battery life in coin-cell-powered devices beyond 1 year. |
| Input Offset Voltage (A-grade) | 800 µV max - ensures ≤0.8 mV DC error in 100× gain stages, critical for sub-mV-level biomedical sensor front-ends. |
| Rail-to-Rail Output Swing | ≤35 mV from rails (RL = 10 kΩ to VCC/2) - maximizes dynamic range in low-voltage ADC interfaces (e.g., 12-bit SAR with 3.3 V reference). |
| Input Bias Current | 1 pA typ - prevents significant voltage drop across high-impedance sources (>100 MΩ), preserving accuracy in pH or photodiode circuits. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in wearable ECG monitors without external RF filtering. |

Use Scenario: Driving red/IR LEDs and amplifying photodiode currents in a wrist-worn SpO₂ module operating from 3.0 V lithium polymer cell. IC Role / Device Role / Timing Role: LED current driver (Ch1), transimpedance amplifier for red PD (Ch2), transimpedance amplifier for IR PD (Ch3), and ambient light cancellation filter (Ch4).

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6294IPT | No A-grade offset spec (max 1 mV vs. 800 µV); otherwise identical pinout, specs, and package. | Suitable where ±1 mV offset is acceptable - e.g., non-critical industrial monitoring with software calibration. | Select TSV6294IPT for cost-sensitive designs where factory calibration compensates for higher offset. |
| TSV6394IPT | Higher supply current (60 µA), 2.4 MHz GBP, unity-gain stable, same TSSOP-14 package. | Required when gain < +4 is needed - e.g., unity-gain buffers or active filters with variable Q tuning. | Choose TSV6394IPT only if stability at gains below +4 is mandatory; otherwise TSV6294AIPT saves >50% quiescent power. |
Compared with TSV6294IPT, the AIPT variant adds guaranteed low-offset performance for precision analog chains; compared with TSV6394IPT, it trades bandwidth and unity-gain stability for micropower efficiency - making it optimal for always-on, battery-constrained sensor nodes.

FAQ
Does TSV6294AIPT have a shutdown pin?
No. The TSV6294AIPT is the non-shutdown variant of the quad op-amp family. Shutdown functionality is only available on the TSV6295 (quad with two shared SHDN pins) and TSV6293 (dual with two SHDN pins). This simplifies PCB layout and reduces control logic overhead in applications where continuous operation is required.
What is the minimum stable gain for TSV6294AIPT?
The TSV6294AIPT requires minimum closed-loop gain of +4 in non-inverting configuration or –3 in inverting configuration to ensure phase margin ≥60° with 100 pF capacitive load. Attempting unity-gain or lower configurations may cause oscillation; for such cases, ST recommends the unity-gain-stable TSV6394IPT instead.
Can TSV6294AIPT drive capacitive loads directly?
It is not optimized for direct capacitive loads >20 pF without isolation resistance. Driving >100 pF loads risks instability unless a series resistor (≥500 Ω) is added between output and capacitance. For ADC input buffering with large sampling capacitors, use a small RC network (e.g., 100 Ω + 1 nF) to maintain stability and settle time.
Is TSV6294AIPT qualified for automotive applications?
While not AEC-Q100 qualified, the TSV6294AIPT operates across –40°C to +125°C and meets industrial reliability standards. It is used in automotive cabin electronics (e.g., seat occupancy sensors, HVAC controls) where full AEC qualification is not mandated, but extended temperature and EMI robustness are essential.
