Product details
Overview
TSV632IST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage operation (1.5 V to 5.5 V), delivering 880 kHz gain-bandwidth product at 60 µA supply current per channel, 800 µV max input offset voltage (A version), and 1 pA typical input bias current - deployed in sensor front-ends and portable medical instrumentation.
For engineers reviewing the TSV632IST datasheet, TSV632IST pinout, TSV632IST application, or TSV632IST equivalent, key selection criteria include shutdown capability (not present in TSV632IST), MiniSO10 package thermal resistance (113 °C/W), EMI rejection ratio up to 92 dB at 1.8 GHz, and guaranteed 0.25 V/µs min slew rate at 5 V.
Technical Context
The TSV632IST uses complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) with no phase reversal. Its output swings within 35 mV of both rails under 10 kΩ load, supporting single-supply signal conditioning without level-shifting.
It features EMI-hardened architecture with EMIRR of 92 dB at 1.8 GHz and 61 dB at 400 MHz, and achieves unity-gain stability driving up to 100 pF capacitive loads - critical for compact PCB layouts in battery-powered systems operating across −40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 V to 5.5 V - enables direct integration with Li-ion, coin-cell, and 3.3 V logic rails without regulators. |
| Gain Bandwidth Product | 880 kHz typ - supports audio-band filtering and sensor signal amplification up to ~100 kHz closed-loop. |
| Supply Current per Channel | 60 µA typ at 5 V - allows >1-year runtime on 100 mAh coin cell in always-on sensor nodes. |
| Input Offset Voltage | 800 µV max (A version) - ensures <0.1% error in 12-bit ADC front-ends with 2.5 V reference. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular/WiFi interference in wearable medical devices without shielding. |
| Common-Mode Rejection | 80 dB min at 5 V - rejects power rail noise in single-supply instrumentation amplifiers. |
Pinout & Package
TSV632IST is housed in a MiniSO10 (10-pin mini-SOIC) package with exposed pad, offering 113 °C/W thermal resistance and compatibility with standard SOIC reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch1) | High-impedance node accepting differential signals; rail-to-rail capable down to VCC− − 0.1 V. |
| 2 | Non-inverting Input (Ch1) | Accepts common-mode voltages up to VCC+ + 0.1 V; critical for single-supply sensor biasing. |
| 3 | Output (Ch1) | Drives loads to within 35 mV of rails; stable with ≤100 pF capacitance in unity-gain configuration. |
| 4 | VCC− | Ground reference for dual-supply or negative rail in single-supply systems; connects to PCB ground plane. |
| 5 | Non-inverting Input (Ch2) | Independent second channel input; identical CMRR and offset specs as Ch1. |
| 6 | Inverting Input (Ch2) | Matches Ch1 performance; enables dual-channel instrumentation or differential pair buffering. |
| 7 | Output (Ch2) | Separate output stage; no crosstalk specified - suitable for isolated signal paths. |
| 8 | VCC+ | Positive supply input; decoupling capacitor (10 nF) required adjacent to pin for stability. |
| 9 | NC | No internal connection - must be left unconnected or tied to ground per layout guidelines. |
| 10 | Exposed Pad | Thermally enhances dissipation; recommended to connect to ground plane for optimal 113 °C/W RθJA. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.5 V–5.5 V single-supply systems without external level shifters. |
| EMI-hardened architecture | 92 dB rejection at 1.8 GHz eliminates need for RF filtering in wireless-adjacent medical wearables. |
| Guaranteed 0.25 V/µs min slew rate | Ensures distortion-free 100 kHz sine wave reproduction at 2 Vpp into 10 kΩ load. |
| 1 pA input bias current | Prevents voltage droop across >1 GΩ sensor sources (e.g., glass pH electrodes) over measurement intervals. |
| −40 °C to +125 °C operation | Validated performance across automotive under-hood and industrial motor-control ambient conditions. |
Applications
| Portable ECG Monitor | Smart Smoke Detector Sensor Front-End |
|---|---|
Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in battery-powered, CE-certified ECG patches. IC Role / Device Role / Timing Role: Dual-channel rail-to-rail op-amp performing DC-coupled gain and active filtering before 12-bit SAR ADC sampling at 1 kHz. Use Value: 1 pA input bias prevents electrode polarization drift; 800 µV max Vos limits baseline error to <0.03% of 2.5 V reference. |
Use Scenario: Conditioning photocurrent from IR LED/photodiode pair in low-power, UL-listed smoke alarms with 10-year coin-cell life. IC Role / Device Role / Timing Role: Transimpedance amplifier converting sub-nA smoke-scattered current into measurable voltage, followed by comparator interface. Use Value: 60 µA/channel quiescent current enables <1 µA system sleep current; EMI hardening rejects switching noise from alarm siren driver. |
| Industrial Temperature Transmitter | Wearable Pulse Oximeter Analog Front-End |
Use Scenario: Signal conditioning for 3-wire RTD bridges in DIN-rail-mounted 4–20 mA loop-powered transmitters operating at 85 °C ambient. IC Role / Device Role / Timing Role: Precision instrumentation-grade amplifier providing 100× gain and cold-junction compensation in analog domain before DAC output stage. Use Value: 80 dB CMRR rejects common-mode noise from 24 V loop supply; 2 µV/°C Vos drift minimizes temperature-induced calibration drift. |
Use Scenario: Dual-path synchronous amplification of red (660 nm) and IR (940 nm) photoplethysmogram (PPG) signals in wrist-worn oximeters. IC Role / Device Role / Timing Role: Two independent low-noise, rail-to-rail op-amps driving ADC inputs with matched gain/phase for ratiometric SpO₂ calculation. Use Value: Matched GBP (880 kHz) and slew rate ensure identical bandwidth response; 60 nV/√Hz input noise preserves weak PPG SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV632AIST | Lower 800 µV max input offset voltage vs. 3 mV for non-A version; same package, pinout, and power specs. | Required where DC accuracy dominates (e.g., precision thermistor readout); not needed for AC-coupled sensor apps. | Select TSV632AIST when Vos budget is <1 mV; otherwise TSV632IST reduces cost without sacrificing speed or power. |
| MCP6022-E/SN | Higher 100 µA supply current, 1 MHz GBP, but lacks EMI hardening and only 65 dB CMRR at 5 V. | Suitable for non-EMI-sensitive industrial controls; unsuitable for medical wearables near cellular bands. | Choose MCP6022-E/SN only if higher bandwidth is mandatory and EMI immunity is verified unnecessary in final layout. |
Compared with TSV632IST, TSV632AIST improves DC precision without trade-offs, while MCP6022-E/SN trades EMI robustness and CMRR for modest bandwidth gain - making TSV632IST optimal for cost-constrained, noise-prone portable instrumentation.

FAQ
Does TSV632IST include a shutdown pin?
No. TSV632IST is the dual-channel variant without shutdown functionality. Shutdown is only available on TSV633 (dual with SHDN) and TSV635 (quad with SHDN) variants. The TSV632IST pinout omits SHDN, and its quiescent current remains fixed at 60 µA per channel across all operating conditions.
What is the maximum capacitive load TSV632IST can drive stably?
TSV632IST is unity-gain stable driving up to 100 pF capacitive load without external compensation. For loads exceeding 100 pF, ST recommends adding a series resistor (e.g., 10–100 Ω) between the output and load to restore phase margin - values are detailed in Figure 22 of the datasheet.
Is the exposed pad on the MiniSO10 package electrically connected?
The exposed pad on TSV632IST's MiniSO10 package is thermally conductive but not internally connected to any die node. ST recommends soldering it to the PCB ground plane to optimize thermal resistance (113 °C/W) and reduce junction temperature during continuous operation.
How does TSV632IST perform at 1.5 V supply?
TSV632IST is fully specified down to 1.5 V: gain-bandwidth remains 730 kHz min, supply current drops to 40 µA typ, and output swing stays within 35 mV of rails. Its rail-to-rail input extends to VCC− − 0.1 V, enabling direct interfacing with 0 V-referenced sensors even at minimum supply.
