Product details
Overview
TSV633AIST from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage operation (1.5 V to 5.5 V), featuring 60 µA typical supply current per channel, 880 kHz gain-bandwidth product, and 800 µV maximum input offset voltage (A-grade). It integrates a dedicated shutdown pin (SHDN) enabling <5 nA quiescent current in disabled state and is qualified for automotive applications (-40 °C to 125 °C).
For engineers reviewing the TSV633AIST datasheet, TSV633AIST pinout, TSV633AIST application, or TSV633AIST equivalent, this device is selected for precision sensor signal conditioning, battery-powered medical instrumentation, and active filtering where rail-to-rail swing, EMI hardening, and stable micropower performance across wide temperature and supply ranges are critical.
Technical Context
The TSV633AIST employs 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 output drives within 35 mV of both rails under 10 kΩ load, supporting single-supply signal chain architectures.
It features a dedicated SHDN pin with VIH = 2 V and VIL = 0.8 V at 5 V supply, enabling fast turn-on (200 ns) and turn-off (20 ns) transitions while placing outputs in high-impedance state. The amplifier remains unity-gain stable driving up to 100 pF capacitive loads.
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 systems |
| Quiescent Current (per channel) | 60 µA typ at 5 V - supports >1-year battery life in always-on sensor nodes |
| Gain Bandwidth Product | 880 kHz typ - sufficient for anti-aliasing filters and DC-coupled biomedical amplifiers |
| Input Offset Voltage (max) | 2.2 mV over full temp range - ensures ≤0.5% error in 1 V full-scale 12-bit ADC front-ends |
| Shutdown Current (all channels) | 5 nA typ at 5 V - reduces system standby power to nanoampere level |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - maintains accuracy in noisy RF environments (e.g., wearable comms) |
| Common-Mode Rejection | 80 dB min at 5 V - rejects supply ripple and shared-noise coupling in multi-channel systems |
Pinout & Package
TSV633AIST is packaged in MiniSO10 (10-lead plastic micro package, 3.0 mm × 4.4 mm, 0.65 mm pitch), RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail capable; sinks/supplies ≥40 mA at 5 V - drives ADC reference buffers or LED bias networks |
| 2 (IN1−) | Channel 1 inverting input | 1 pA typical input bias current - minimizes voltage error in high-Z sensor interfaces (e.g., pH electrodes) |
| 3 (IN1+) | Channel 1 non-inverting input | Part of complementary input pair enabling rail-to-rail CMVR - supports direct connection to thermistor dividers |
| 4 (VCC−) | Negative supply | Ground reference for single-supply operation; exposed pad (if present) must be connected to VCC− or left floating |
| 5 (IN2+) | Channel 2 non-inverting input | Independent high-impedance node - allows differential sensing with matched channel pairs |
| 6 (IN2−) | Channel 2 inverting input | 1 pA typical bias current - preserves gain accuracy in transimpedance configurations |
| 7 (OUT2) | Channel 2 output | Unity-gain stable into 100 pF - suitable for driving SAR ADC sample-and-hold inputs |
| 8 (SHDN) | Global shutdown control | Active-low logic input; pulls all four outputs to high-Z when low - enables synchronized power gating |
| 9 (OUT3) | Channel 3 output | Identical specs to OUT1/OUT2 - supports triple-signal-path designs (e.g., 3-axis accelerometer conditioning) |
| 10 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal regulation ensures consistent GBP and SR across voltage range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV633IST | Standard grade (4.5 mV max Vio vs. 2.2 mV), no A-grade trimming - higher offset uncertainty at temperature extremes | Suitable for non-critical industrial monitoring where ±5 mV offset is acceptable | Select when cost sensitivity outweighs precision requirements and full-temp-range accuracy is not mandated |
| MCP6004-E/SL | Higher supply current (100 µA/channel), lower GBP (1 MHz), no shutdown pin - lacks nanoamp shutdown and automotive temp support | Targeted at general-purpose consumer electronics, not automotive or medical-certified designs | Choose only for cost-driven, non-automotive applications requiring basic rail-to-rail performance without shutdown or AEC-Q100 compliance |
Compared with TSV633IST, the TSV633AIST delivers tighter offset (2.2 mV vs. 4.5 mV) and guaranteed automotive qualification; versus MCP6004-E/SL, it offers 40% lower quiescent current, integrated shutdown, and robust EMI immunity - making it uniquely suited for safety-critical, battery-constrained, and RF-hostile environments.

FAQ
What is the minimum supply voltage for reliable operation of TSV633AIST?
The TSV633AIST is fully specified and guaranteed to operate down to 1.5 V supply voltage, with key parameters including gain-bandwidth product, input offset voltage, and output swing validated at 1.5 V, 1.8 V, 3.3 V, and 5 V. Operation below 1.5 V may result in undefined behavior or failure to meet datasheet limits.
Can TSV633AIST drive a 100 kΩ load while maintaining rail-to-rail output swing?
Yes - the TSV633AIST maintains rail-to-rail output capability (within 35 mV of rails) into resistive loads ≥10 kΩ, and its output stage can source/sink ≥40 mA at 5 V. Driving 100 kΩ poses no loading concern and preserves full swing; however, slew rate and bandwidth remain unaffected only if capacitive load stays ≤100 pF.
Is the SHDN pin compatible with 1.8 V logic levels?
No - the SHDN pin requires VIH ≥2.0 V and VIL ≤0.8 V at 5 V supply, meaning it is not 1.8 V logic-compatible. When operating from 1.8 V supply, VIH is specified as 1.35 V and VIL as 0.6 V, so direct interface with 1.8 V GPIO is valid only if the controller's VOH exceeds 1.35 V and VOL stays below 0.6 V under load.
Does TSV633AIST require external compensation for unity-gain stability?
No - the TSV633AIST is internally compensated and unity-gain stable, verified with up to 100 pF capacitive load. No external compensation components are needed for standard follower or inverting configurations; adding series resistance at the output is only recommended for loads exceeding 100 pF to maintain phase margin.
