Product details
Overview
TSV6391AICT from STMicroelectronics is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for micropower precision applications. It delivers 2.4 MHz gain bandwidth at just 60 µA supply current (5 V), supports 1.5–5.5 V operation, and features 500 µV max offset voltage (A-grade), enabling high-accuracy signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV6391AICT datasheet, TSV6391AICT pinout, TSV6391AICT application, or TSV6391AICT equivalent, key selection criteria include its 1 pA typical input bias current, 63 mA output drive capability at 5 V, -40 °C to 125 °C industrial temperature range, and SC70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TSV6391AICT uses complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its internal compensation ensures stability at closed-loop gains ≥4 (non-inverting) or ≥11 (inverting) with 100 pF load capacitance.
It lacks shutdown functionality (distinguishing it from TSV6390 variants), operates down to 1.5 V supply, and maintains 80 dB CMRR and 93 dB SVR across full voltage and temperature range - critical for low-drift sensor front-ends and active filtering in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration with Li-ion, coin-cell, and 3.3 V logic rails without LDO overhead. |
| Quiescent Current | 60 µA typical at 5 V - extends battery life in always-on wearable and IoT sensor nodes beyond 10 years on CR2032. |
| Gain Bandwidth Product | 2.4 MHz - supports 10 kHz anti-aliasing filters with >60 dB attenuation while maintaining phase margin ≥60°. |
| Input Offset Voltage | ≤500 µV (max, A-grade) - reduces DC error to <0.1% FS in 5 V full-scale bridge sensor amplifiers. |
| Input Bias Current | 1 pA typical - prevents leakage-induced drift in high-impedance pH or photodiode transimpedance circuits. |
| Rail-to-Rail I/O | Output swings within 35 mV of rails into 10 kΩ - maximizes dynamic range in single-supply data acquisition systems. |
| ESD Robustness | 4 kV HBM - withstands handling and board-level ESD events without protection diodes or layout derating. |
Pinout & Package
TSV6391AICT is housed in a 5-pin SC70-5 (SOT323-5) package - 2.0 mm × 2.1 mm footprint, 0.65 mm pitch, 0.9 mm height - optimized for ultra-dense portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail swing up to ±63 mA; requires local 10 nF decoupling to maintain stability at 2.4 MHz. |
| 2 (−IN) | Inverting Input | High-impedance node (1 pA bias); sensitive to layout parasitics - must be routed short and guarded in precision designs. |
| 3 (V−) | Negative Supply | Ground reference for single-supply operation; connects to system GND or negative rail in dual-supply configurations. |
| 4 (+IN) | Non-inverting Input | Matches −IN characteristics; rail-to-rail common-mode range allows direct connection to 0–5 V sensor outputs. |
| 5 (V+) | Positive Supply | Accepts 1.5–5.5 V; internal regulation ensures consistent 60 µA ICC across voltage range for predictable power budgeting. |
Key Features
| Feature | Design Value |
|---|---|
| Low Power Precision | 60 µA ICC + 500 µV Vio max enables µA-level sensor signal amplification without sacrificing DC accuracy. |
| Rail-to-Rail Operation | Full 0–5 V input and output swing preserves 99% of ADC dynamic range in 5 V single-supply systems. |
| Wide Temperature Range | Guaranteed performance from −40 °C to +125 °C supports under-hood automotive and industrial field deployments. |
| High Output Drive | 63 mA sink/source capability drives 10 kΩ loads directly - eliminates need for external buffer stages in analog front-ends. |
| Low Noise Performance | 60 nV/√Hz at 1 kHz enables clean amplification of microvolt-level biopotential signals (ECG, EEG). |
Applications
| Medical Sensor Interface | Portable Gas Detector |
|---|---|
|

IC Role / Device Role / Timing Role: Rail-to-rail input/output buffer isolating sensor output from ADC input while preserving full-scale range. Use Value: 1.5 V minimum supply allows direct use with partially discharged lithium batteries; 60 µA ICC extends logging interval to >2 years. |
| Wearable Biometric Front-End | Industrial Current Loop Receiver |
|
Use Scenario: Amplifying photoplethysmography (PPG) signals in smartwatches with optical heart-rate monitoring. IC Role / Device Role / Timing Role: Low-noise, low-power gain stage preceding ADC sampling at 100 Hz–1 kHz. Use Value: 60 nV/√Hz input noise floor resolves sub-millivolt AC PPG pulses; rail-to-rail output matches 12-bit SAR ADC input range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6391ICT | Higher 3 mV max offset voltage (vs. 500 µV for A-grade); otherwise identical specs and pinout. | Suitable for cost-sensitive consumer applications where <0.1% gain error is acceptable. | Select when DC accuracy requirements are relaxed and BOM cost reduction is prioritized over calibration effort. |
| MCP6001T-E/OT | Lower 1 µA ICC but only 1 MHz GBP; 2 mV Vio max; same SC70-5 package and 1.8–6 V supply range. | Better for ultra-low-power wake-up circuits; insufficient bandwidth for >50 kHz active filtering. | Choose for sub-µA standby modes where speed is secondary - not for precision wideband signal chains. |
Compared with TSV6391ICT, the TSV6391AICT trades higher unit cost for 6× lower offset voltage - reducing system-level calibration steps. Against MCP6001T-E/OT, it delivers 2.4× more bandwidth at only 60× higher quiescent current, making it optimal for battery-powered precision analog front-ends requiring both speed and accuracy.

FAQ
Is TSV6391AICT unity-gain stable?
No, TSV6391AICT is not unity-gain stable. It requires minimum closed-loop gain of 4 (non-inverting) or 11 (inverting) for stability with 100 pF capacitive load. For unity-gain applications, ST recommends the TSV6291 or TSV6301, which are explicitly characterized for stability at G = 1.
What is the maximum capacitive load the TSV6391AICT can drive?
The TSV6391AICT is characterized for stability with up to 100 pF capacitive load when configured with gain ≥4 (non-inverting) or ≥11 (inverting). Driving larger capacitive loads requires external isolation resistance (e.g., 10–100 Ω in series with output) or careful PCB layout to avoid peaking and oscillation.
Does TSV6391AICT have a shutdown pin?
No, TSV6391AICT does not include a shutdown function. That feature is exclusive to the TSV6390 series (e.g., TSV6390AICT). The TSV6391AICT is a simplified, 5-pin variant optimized for cost and size in applications where continuous operation is required.
Can TSV6391AICT operate from a 1.5 V supply?
Yes, TSV6391AICT is fully specified down to 1.5 V supply voltage. At 1.5 V, it maintains 60 µA typical supply current, rail-to-rail I/O, and functional gain bandwidth - enabling direct interface with primary alkaline or lithium-thionyl chloride cells without voltage boosting.
