Product details
Overview
TSV6290AICT from STMicroelectronics is a micropower rail-to-rail input/output CMOS operational amplifier with 1.3 MHz gain bandwidth, 29 µA supply current, and 800 µV max input offset voltage (A-grade), designed for precision signal conditioning in ultra-low-power battery-powered systems.
For engineers reviewing the TSV6290AICT datasheet, TSV6290AICT pinout, TSV6290AICT application, or TSV6290AICT equivalent, this device requires minimum closed-loop gain ≥4, supports shutdown control, operates from 1.5 V to 5.5 V, and delivers rail-to-rail output swing within 35 mV of supply rails under 10 kΩ load.
Technical Context
The TSV6290AICT integrates complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (–0.1 V to VCC + 0.1 V) and achieves stable operation only in non-inverting configurations with gain ≥4 or inverting configurations with |gain| ≥3 (CL = 20 pF, RL = 100 kΩ).
It features a dedicated SHDN pin that places the amplifier in high-impedance shutdown mode with 5 nA typical ICC (shutdown), 300 ns turn-on time, and logic-compatible thresholds (VIH = 4.5 V @ VCC = 5 V, VIL = 0.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion, alkaline, or NiMH batteries without regulation. |
| Quiescent Current | 29 µA typical - extends battery life in always-on sensor nodes and portable medical devices. |
| Input Offset Voltage (A-grade) | ≤800 µV max - ensures <0.1% error in 12-bit ADC front-end applications at room temperature. |
| Gain Bandwidth Product | 1.3 MHz typical - supports anti-aliasing filtering up to ~100 kHz with unity-gain stability margin. |
| Rail-to-Rail Output Swing | Within 35 mV of VCC and GND @ 10 kΩ load - maximizes dynamic range in low-voltage data acquisition. |
| Input Bias Current | 1 pA typical - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Shutdown Current | 5 nA typical @ VCC = 5 V - reduces system standby power by >5,000× versus active mode. |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive cabin, industrial motor control, and outdoor IoT deployments. |
Pinout & Package
TSV6290AICT is supplied in SC70-6 package (2.0 × 2.1 mm, 0.65 mm pitch), optimized for space-constrained portable designs. Pin functions are validated per STMicroelectronics DocID17117 Rev 2, Figure 27 and Table 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts signals from –0.1 V to VCC + 0.1 V; compatible with direct sensor connection without level-shifting. |
| 2 (IN–) | Inverting input | Differential pair node; used for feedback network attachment in precision gain-setting configurations. |
| 3 (V–) | Negative supply / ground | Reference for all internal biasing; must be connected to system ground or negative rail. |
| 4 (SHDN) | Shutdown control input | Active-low enable: pulled to V– disables amplifier and forces output to high-Z state. |
| 5 (OUT) | Amplifier output | Drives loads down to 10 kΩ while maintaining rail-to-rail swing and <0.15% THD @ 1 kHz. |
| 6 (V+) | Positive supply | Accepts 1.5–5.5 V; decoupling capacitor (10 nF) required adjacent to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 29 µA supply current enables >1-year battery life in coin-cell-powered wireless sensors. |

Applications
| Wearable Heart Rate Monitor | Portable Gas Sensor Interface |
|---|---|

IC Role / Device Role / Timing Role: Precision transimpedance amplifier with rail-to-rail output driving 12-bit SAR ADC input. Use Value: 1 pA input bias current prevents DC drift in high-impedance photodiode path; 29 µA quiescent current extends battery runtime beyond 6 months. |
Use Scenario: Conditioning low-amplitude analog output from electrochemical gas detection cells in handheld air quality meters. IC Role / Device Role / Timing Role: Low-noise, zero-drift signal conditioner with programmable gain before sigma-delta ADC.

|
Use Scenario: Signal amplification and cold-junction compensation for thermocouple inputs in DIN-rail-mounted process controllers. IC Role / Device Role / Timing Role: Rail-to-rail input op-amp in precision instrumentation amplifier configuration with RTD reference. Use Value: –40 °C to +125 °C operating range matches industrial ambient requirements; 2 μV/°C VIO drift minimizes calibration frequency. |
Use Scenario: Amplifying ionization chamber current in battery-operated residential smoke alarms with 10-year shelf life. IC Role / Device Role / Timing Role: Micropower transimpedance amplifier enabling ultra-low standby current and fast alarm response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6291AICT | No shutdown pin; SOT23-5/SC70-5 footprint; identical electrical specs except missing SHDN function. | Suitable where board space is constrained and shutdown is unnecessary (e.g., always-on sensor nodes). | Select when system-level power sequencing is handled externally and SC70-5's smaller footprint (1.8 × 2.0 mm) is critical. |
| MCP6001T-E/OT | Higher 100 µA supply current; 1 MHz GBP; no guaranteed A-grade VIO; same SC70-5 package. | Less suitable for multi-year battery life targets but offers broader gain stability (unity-gain stable). | Choose only if unity-gain operation is mandatory and 29 µA quiescent current is not required. |
Compared with TSV6290AICT, TSV6291AICT removes shutdown capability to reduce pin count and cost, while MCP6001T-E/OT trades micropower performance for unconditional unity-gain stability-neither matches the combination of A-grade precision, 29 µA consumption, and integrated shutdown in SC70-6.

FAQ
What is the minimum closed-loop gain required for stable operation of TSV6290AICT?
The TSV6290AICT is not unity-gain stable and requires minimum closed-loop gain ≥4 in non-inverting configurations or |gain| ≥3 in inverting configurations (with CL = 20 pF, RL = 100 kΩ). Operation below these gains risks peaking or oscillation, as confirmed in Figures 5–7 of the datasheet.
Can TSV6290AICT operate from a 1.5 V supply?
Yes - TSV6290AICT is fully specified and characterized down to 1.5 V supply voltage, with guaranteed rail-to-rail input/output, 29 µA supply current, and 1.1 MHz GBP at 1.5 V (Table 3). It maintains functionality across the full 1.5–5.5 V range without derating.
How does the SHDN pin behave during power-up?
The SHDN pin must never float; it must be tied to V+ or V– at power-up. If pulled low during startup, the amplifier remains disabled until SHDN rises above VIH (4.5 V @ 5 V supply). Turn-on time is 300 ns to reach 200 mV output swing, verified in Figure 22.
Is TSV6290AICT pin-compatible with other SC70-6 op-amps?
No - TSV6290AICT uses a non-standard SC70-6 pinout (IN+, IN–, V–, SHDN, OUT, V+) that differs from industry-standard dual-supply or single-supply SC70-6 op-amps. Direct replacement requires PCB layout revision and validation of shutdown timing and gain stability.
