Product details
Overview
TSV620ICT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, precision signal conditioning in battery-powered systems. It operates from 1.5 V to 5.5 V, consumes 29 µA typical supply current at 5 V, delivers 420 kHz gain bandwidth, and features a shutdown mode drawing only 5 nA typical. Its 800 µV max input offset voltage (A version), 1 pA typical input bias current, and –40 °C to +125 °C industrial temperature range make it ideal for portable medical sensors and low-voltage data acquisition.
For engineers reviewing the TSV620ICT datasheet, TSV620ICT pinout, TSV620ICT application, or TSV620ICT equivalent, key selection criteria include its SC70-6 package footprint, SHDN-controlled power gating, rail-to-rail I/O swing within 35 mV of rails, and guaranteed unity-gain stability with ≤100 pF capacitive loads - all critical for space-constrained, energy-sensitive analog front-ends.
Technical Context
The TSV620ICT implements dual complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range from (VCC–) –0.1 V to (VCC+) +0.1 V, with no phase reversal across the transition region near VCC – 0.7 V. Its internal trimming ensures tight dispersion of DC/AC parameters: supply current ±17%, GBP ≥350 kHz min, and slew rate ≥0.15 V/µs min.
It integrates a logic-compatible shutdown pin (VIH = 4.5 V, VIL = 0.5 V at VCC = 5 V) that places the output in high-impedance state with 300 ns turn-on and 30 ns turn-off times. The device maintains 45° phase margin and 9 dB gain margin while driving 10 kΩ loads, and sustains 4 kV HBM ESD robustness without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct operation from single-cell Li-ion (3.0–3.7 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Quiescent Current | 29 µA typ at 5 V - extends battery life in always-on sensor nodes; drops to 5 nA in shutdown mode for multi-year standby. |
| Gain Bandwidth Product | 420 kHz typ at 5 V - supports accurate amplification of DC–400 kHz signals (e.g., ECG, pulse oximetry) with minimal phase error. |
| Input Offset Voltage | 0.8 mV max (TSV620A variant) - reduces baseline drift in precision instrumentation amplifiers and bridge sensor interfaces. |
| Rail-to-Rail Output Swing | Within 35 mV of VCC+ and VCC– into 10 kΩ - maximizes dynamic range in low-voltage ADC driver applications. |
| Input Bias Current | 1 pA typ - prevents loading errors in high-impedance pH electrodes, photodiode transimpedance stages, and piezoelectric sensors. |
| ESD Robustness | 4 kV HBM - eliminates need for external ESD protection diodes in handheld diagnostic devices and wearable electronics. |
Pinout & Package
TSV620ICT is housed in a 6-pin SC70-6 (SOT323-6) micropackage measuring 2.20 mm × 1.35 mm × 0.90 mm, compatible with high-density PCB layouts and reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC+ | Positive supply rail - must be decoupled with 10 nF capacitor placed <1 mm from pin to minimize noise coupling. |
| 2 | In– | Inverting input - high-impedance node; sensitive to layout parasitics; requires guard ring in high-gain configurations. |
| 3 | In+ | Non-inverting input - referenced to system ground or bias network; 1 pA bias current enables use with >100 MΩ source impedances. |
| 4 | Out | Amplifier output - capable of sourcing/sinking 40–69 mA; remains stable driving ≤100 pF capacitive loads without series resistance. |
| 5 | SHDN | Active-low shutdown control - pulled high (>4.5 V) to enable; pulled low (<0.5 V) to disable; must never float. |
| 6 | VCC– | Negative supply rail (typically GND) - serves as reference for input common-mode and output swing; shared return path for decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Dual complementary PMOS/NMOS pair extends common-mode range to (VCC–) –0.1 V and (VCC+) +0.1 V, eliminating input clipping in single-supply sensor interfaces. |
| Ultra-low input bias current | 1 pA typical enables direct connection to high-impedance sources like glass pH electrodes and photodiodes without signal degradation. |
| Guaranteed unity-gain stability | Stable with capacitive loads up to 100 pF - removes need for external compensation in ADC buffer and filter applications. |
| Tight parameter dispersion | ±17% spread on supply current ensures consistent GBP and slew rate across production lots, simplifying design validation. |
| Industrial temperature grade | Specified from –40 °C to +125 °C - supports deployment in automotive cabin modules, industrial IoT edge nodes, and medical equipment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV620AILT | Same core specs but in SOT23-6 package; 0.8 mV max VOS (A-grade) vs. standard TSV620ICT's 2.8 mV max. | Better DC precision required; board space allows larger SOT23-6 footprint. | Select when offset-critical DC accuracy outweighs SC70-6 size advantage. |
| MCP6001T-E/OT | Higher 100 kHz GBP, 100 nA IQ, no shutdown pin; 2.7–5.5 V supply range only. | Lower performance tier; suitable for cost-sensitive, non-shutdown applications with wider supply margins. | Choose if shutdown function is unnecessary and 100 kHz bandwidth suffices for signal chain. |
Compared with TSV620ICT, TSV620AILT offers tighter offset specification in a larger package, while MCP6001T-E/OT trades shutdown capability and ultra-low IQ for lower cost and relaxed supply requirements - guiding selection based on precision, size, and power-control priorities.

FAQ
What is the maximum capacitive load the TSV620ICT can drive without oscillation?
The TSV620ICT is unity-gain stable and characterized to drive up to 100 pF capacitive loads without external compensation. Driving larger loads requires adding a small series resistor (e.g., 10–100 Ω) between the output and the load capacitance, with final stability verified via bench testing and SPICE simulation using ST's official macromodel.
Does the TSV620ICT require external input protection diodes?
No. The TSV620ICT incorporates internal ESD protection rated to 4 kV HBM on all pins, making external diodes unnecessary for typical handling and board-level ESD events. However, sustained overvoltage conditions beyond absolute maximum ratings (e.g., >6 V supply or >±VCC differential input) still require external clamping.
How does the shutdown function affect output state and leakage?
When SHDN is pulled low, the amplifier disables and the output enters a high-impedance state with ≤1 nA leakage current over temperature. The output does not short to either rail; it floats. Turn-off time is 30 ns, and turn-on time is 300 ns - fast enough for duty-cycled sensor readouts without compromising measurement timing.
Can the TSV620ICT operate from a 1.5 V alkaline battery throughout its discharge curve?
Yes. The TSV620ICT is fully specified down to 1.5 V supply and maintains rail-to-rail input/output operation, 420 kHz GBP, and 29 µA IQ across the entire 1.5–5.5 V range. Its performance remains stable as the battery discharges from 1.5 V to ~1.0 V, though GBP and slew rate decrease gradually below 1.5 V.
