Product details

Overview

TSV620AICT 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 delivers 420 kHz gain bandwidth at 29 µA supply current (5 V), 800 µV max input offset voltage (A-grade), and operates from 1.5 V to 5.5 V - enabling use in medical sensors and portable instrumentation where supply headroom and quiescent power are critical.

For engineers reviewing the TSV620AICT datasheet, TSV620AICT pinout, TSV620AICT application, or TSV620AICT equivalent, key selection criteria include its shutdown-enabled architecture (SHDN pin), 4 kV HBM ESD rating, -40 °C to +125 °C industrial temperature range, SC70-6 package footprint, and verified unity-gain stability with ≤100 pF capacitive loads.

Technical Context

The TSV620AICT integrates complementary PMOS/NMOS input pairs to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and output swing within 35 mV of both rails under 10 kΩ load. Its internal trimming ensures tight dispersion of DC/AC parameters - including ±17% spread on 29 µA typical ICC and guaranteed minima of 350 kHz GBP and 0.15 V/µs slew rate.

Unlike standard micropower op-amps, it features a dedicated active-low SHDN pin (VIH = 4.5 V, VIL = 0.5 V at 5 V) that reduces supply current to 5 nA typ while placing the output in high-impedance state; turn-on/turn-off times are 300 ns and 30 ns respectively, supporting dynamic power gating in energy-constrained designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.5 V–5.5 V - enables direct operation from single Li-ion, coin cell, or regulated low-voltage rails without LDO pre-regulation.
Gain Bandwidth Product	420 kHz typ at 5 V - supports anti-aliasing filtering and sensor amplification up to ~40 kHz with stable unity-gain configuration.
Input Offset Voltage	800 µV max (A version) - ensures ≤0.016% error in 5 V full-scale 12-bit ADC front-ends without trimming.
Quiescent Current	29 µA typ at 5 V - extends battery life beyond 1 year in always-on wearable sensors drawing <10 µA average system current.
Shutdown Current	5 nA typ - reduces standby power by >5,000× versus active mode, critical for intermittent-sampling architectures.
ESD Rating	4 kV HBM - meets IEC 61000-4-2 Level 2 for handheld medical devices handling direct user contact.
Operating Temperature	-40 °C to +125 °C - qualified for under-hood automotive cabin modules and industrial motor control feedback paths.

Pinout & Package

TSV620AICT is supplied in SC70-6 (SOT323-6) package: 1.8 mm × 2.2 mm × 0.9 mm body, 0.65 mm lead pitch, coplanar gull-wing leads. Thermal resistance R_thJA = 232 °C/W.

Pin	Circuit Role	Design Meaning
1	V_CC+	Positive supply rail - must be decoupled with ≥10 nF ceramic capacitor placed within 2 mm of pin.
2	In−	Inverting input - high-impedance (1 pA bias current) node; sensitive to PCB leakage and guarding required in pH/thermocouple interfaces.
3	In+	Non-inverting input - rail-to-rail common-mode range allows direct connection to resistive divider outputs down to GND or up to V_CC+.
4	Out	Amplifier output - capable of sourcing/sinking 40–69 mA (5 V), but specified stable only with ≥5 kΩ resistive or ≤100 pF capacitive loads.
5	SHDN	Active-low shutdown control - logic high (>4.5 V) enables amplifier; floating state is undefined and must be avoided via pull-up/pull-down.
6	V_CC−	Negative supply rail (typically GND) - serves as reference for SHDN threshold and output swing baseline.

Key Features

Feature	Design Value
Rail-to-rail I/O with 35 mV headroom	Enables full utilization of 1.8 V–5.5 V supply range in single-supply data acquisition, eliminating level-shifting circuitry.
Guaranteed 350 kHz min GBP	Ensures consistent small-signal bandwidth across production lots, simplifying filter design and reducing calibration overhead.
Internal DC/AC parameter trimming	Reduces ICC spread to ±17%, directly improving predictability of battery lifetime and thermal behavior in volume production.
Unity-gain stable with 100 pF load	Permits direct driving of ADC input capacitance or long PCB traces without external compensation components.
4 kV HBM ESD protection	Eliminates need for external TVS diodes in Class II portable medical devices, reducing BOM count and board area.

Applications

Medical Sensor Interface

Portable Gas Detector

Use Scenario: Amplifying microvolt-level signals from electrochemical gas sensors with 100 kΩ–1 MΩ source impedance.

IC Role / Device Role / Timing Role: Precision transimpedance amplifier with rail-to-rail input enabling zero-bias operation and low-noise (<70 nV/√Hz) signal conditioning.

Use Value: 1 pA input bias current prevents sensor polarization; 800 µV max V_os maintains <±0.5% full-scale accuracy over temperature without recalibration.

Use Scenario: Conditioning thermistor and NDIR detector outputs in handheld air quality monitors powered by CR2032 coin cells.

IC Role / Device Role / Timing Role: Low-power buffer and active filter stage operating from 3 V supply with shutdown controlled by MCU GPIO during sleep cycles.

Use Value: 29 µA active current + 5 nA shutdown current extends 250 mAh coin cell life to >18 months at 1-sample-per-minute duty cycle.

Battery Management System

Industrial Temperature Transmitter

Use Scenario: Measuring cell voltage in 2–4 cell Li-ion packs with integrated protection ICs, requiring high-impedance sensing and wide common-mode range.

IC Role / Device Role / Timing Role: High-side current sense amplifier front-end with rail-to-rail input tracking V_BAT up to 16.8 V (via resistor divider).

Use Value: Input common-mode range extending to V_CC+ +0.1 V allows accurate measurement even when V_CC droops below cell voltage during load transients.

Use Scenario: Signal conditioning for Pt100 RTD bridges in 4–20 mA loop-powered field transmitters deployed in chemical plants.

IC Role / Device Role / Timing Role: Precision instrumentation amplifier driver with 125 °C rated operation and 4 kV HBM robustness for harsh industrial environments.

Use Value: Guaranteed performance from -40 °C to +125 °C eliminates derating; 4 kV ESD withstand prevents field failures due to maintenance personnel static discharge.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rail-to-rail, low-power operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP6001T-E/OT (Microchip)	Higher 100 µA ICC, no shutdown pin, 1 MHz GBP, 2.7 V–6 V supply range.	Lacks power-gating capability; unsuitable for intermittent-sampling systems requiring nanoamp shutdown.	Select when higher bandwidth is needed and supply ≥2.7 V is guaranteed; avoid where <30 µA quiescent current is mandatory.
TLV851DBVR (TI)	25 µA ICC, no shutdown, 10 kHz GBP, 1.8 V–6 V supply, 3 mV max V_os (non-A grade).	Lower bandwidth limits use in active filters above 1 kHz; higher offset degrades DC-critical sensor chains.	Prefer for ultra-low-power biasing or comparator-like functions; not recommended for precision analog front-ends requiring <1 mV offset.

Compared with MCP6001T-E/OT and TLV851DBVR, the TSV620AICT uniquely combines sub-30 µA operation, A-grade 800 µV offset, integrated shutdown, and 420 kHz bandwidth - making it the only option among the three qualified for battery-powered medical sensors requiring both precision and dynamic power control.

FAQ

Does TSV620AICT require external compensation for unity-gain stability?

No. The TSV620AICT is internally compensated for unity-gain stability and remains stable driving capacitive loads up to 100 pF without external components. This is verified across all supply voltages (1.5 V–5.5 V) and temperatures (-40 °C to +125 °C), per datasheet Section 3.5 and Figure 6–7.

What is the maximum capacitive load the output can drive without oscillation?

The output is guaranteed stable with ≤100 pF capacitive load in unity-gain follower configuration. Driving larger capacitances (e.g., ADC input or long cables) requires adding a series resistor (10–100 Ω, per Figure 20) between the output and load to isolate capacitance and preserve phase margin.

Can the SHDN pin be left unconnected or tied to V_CC+ through a high-value resistor?

No. The SHDN pin must never float - datasheet Section 3.4 explicitly states it must be tied to either V_CC+ (to enable) or V_CC− (to disable). A pull-up resistor to V_CC+ is acceptable, but values >100 kΩ risk noise-induced toggling; 10 kΩ is recommended for robust logic-level control.

Is the 800 µV max input offset voltage specified over temperature?

The 800 µV maximum applies at T_A = 25 °C. Over the full -40 °C to +125 °C range, max V_IO increases to 2.8 mV (Table 3–6), with drift of 2 µV/°C. For DC-critical applications, this 2.8 mV worst-case value must be used in error budget calculations.
