Product details
Overview
TSV630AICT 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 880 kHz gain bandwidth at 60 µA supply current (5 V), 500 µV max offset voltage (A-grade), 1 pA typical input bias current, and operates from 1.5 V to 5.5 V - enabling use in medical sensors, portable instrumentation, and automotive body electronics.
For engineers reviewing the TSV630AICT datasheet, TSV630AICT pinout, TSV630AICT application, or TSV630AICT equivalent, key selection criteria include its shutdown functionality (5 nA typ ICC in shutdown), rail-to-rail output swing (≤35 mV from rails), extended temperature range (–40 °C to 125 °C), and guaranteed unity-gain stability with 100 pF capacitive loads.
Technical Context
The TSV630AICT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V) and features internal trimming for tight parameter dispersion - including ±17% variation in supply current and guaranteed minimum GBP (730 kHz) and slew rate (0.25 V/µs). Its shutdown pin (SHDN) controls high-impedance output state with 300 ns turn-on and 20–30 ns turn-off times.
It supports single-supply operation down to 1.5 V, maintains >80 dB CMRR and >102 dB SVR at 5 V, and drives up to 69 mA sink/source while preserving low THD (0.0017% at 1 kHz, 2 VPP). The device is unity-gain stable without external compensation and includes ESD protection (4 kV HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V/5 V logic rails without level shifting. |
| Quiescent Current | 60 µA typ at 5 V - extends battery life in always-on sensor nodes and wearable devices. |
| Offset Voltage (A-grade) | 500 µV max (–40 °C to 125 °C) - ensures <1 LSB error in 12-bit ADC front-ends with gain ≤10. |
| Gain Bandwidth Product | 880 kHz typ - supports anti-aliasing and active filtering up to ~100 kHz with stable phase margin (>50°). |
| Input Bias Current | 1 pA typ - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes). |
| Shutdown Current | 5 nA typ - reduces system standby power to nanoampere levels during sleep cycles. |
| Rail-to-Rail I/O | Input CM range: VCC– – 0.1 V to VCC+ + 0.1 V; Output swing: within 35 mV of rails (10 kΩ load) - maximizes dynamic range in low-voltage systems. |
| Operating Temperature | –40 °C to 125 °C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
TSV630AICT is supplied in the SC70-6 (SOT323-6) package: 1.3 mm × 1.0 mm × 0.9 mm, 6-pin surface-mount, lead-free and RoHS-compliant. Pin 1 marked by dot; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low enable: tie to VCC+ to operate; pull to VCC– to enter 5 nA shutdown mode with high-Z output. |
| 2 (IN–) | Inverting input | Differential input node; 1 pA bias current enables high-impedance feedback networks without significant error. |
| 3 (IN+) | Non-inverting input | Rail-to-rail input stage allows sensing signals from 0 V to VCC without clipping. |
| 4 (VCC–) | Negative supply / ground | Reference for all internal circuitry; decoupling capacitor (10 nF) required adjacent to pin. |
| 5 (OUT) | Amplifier output | Capable of 63 mA drive at 5 V; rail-to-rail swing supports full-scale output into ADC reference buffers. |
| 6 (VCC+) | Positive supply | Accepts 1.5–5.5 V; PSRR >102 dB ensures immunity to supply noise in mixed-signal PCBs. |
Key Features

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 |
|---|---|---|---|
| TSV621ICT | Lower power (29 µA), lower GBP (420 kHz), no shutdown function | Better suited for always-on, bandwidth-constrained monitoring (e.g., thermistor readout) where shutdown is unnecessary | Select when priority is lowest possible ICC and bandwidth ≤200 kHz; avoid if shutdown or >600 kHz response required. |
| MCP6001T-E/OT | Higher offset (1.5 mV max), no A-grade option, 100 nA shutdown current vs. 5 nA | Cost-optimized general-purpose replacement; lacks automotive qualification and tight offset spec | Select for non-automotive consumer designs where 500 µV offset and AEC-Q100 are not mandatory. |
Compared with TSV630AICT, TSV621ICT trades 47% lower supply current for 52% reduced bandwidth and loss of shutdown control, while MCP6001T-E/OT offers broader availability but sacrifices precision, temperature range, and shutdown efficiency - making TSV630AICT optimal for automotive-qualified, battery-sensitive, high-accuracy applications.

FAQ
What is the maximum capacitive load the TSV630AICT can drive without external compensation?
The TSV630AICT is unity-gain stable with capacitive loads up to 100 pF when configured as a voltage follower. For larger loads, an in-series resistor (e.g., 10–100 Ω) at the output is recommended to maintain phase margin above 48°, as verified in Figure 23 of the datasheet. Stability must be confirmed experimentally for each specific layout and load condition.
Does the TSV630AICT require external passive components for basic operation?
Yes - a 10 nF ceramic decoupling capacitor must be placed as close as possible to the VCC+ and VCC– pins to suppress supply noise and prevent oscillation. No external compensation is needed for unity-gain stability, but feedback resistors and input biasing networks are required per application circuit topology (e.g., inverting/non-inverting amplifier, transimpedance configuration).
How does the shutdown function affect output behavior?
When SHDN is pulled low (to VCC–), the amplifier output enters a high-impedance state with leakage current ≤1 nA over –40 °C to 125 °C. The output does not short or clamp - it floats - so external pull-up/down resistors may be needed depending on downstream logic requirements. Turn-off time is 20–30 ns; turn-on time is 300 ns.
Is the TSV630AICT pin-compatible with other variants in the TSV63x family?
Yes - TSV630AICT shares identical SC70-6 pinout with TSV630ICT, TSV631AICT, and TSV631ICT. The 'A' suffix denotes tighter offset voltage (500 µV max vs. 3 mV max), and '0' vs. '1' indicates single (TSV630) vs. dual (TSV631) channel count. Functionally, only TSV630/TSV630A include the SHDN pin; TSV631/TSV631A omit it.
