Product details
Overview
TSV632AIST 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 per channel, 800 µV max input offset voltage (A-grade), and 1 pA typical input bias current - ideal for precision sensor signal conditioning in battery-powered medical and portable instrumentation.
For engineers reviewing the TSV632AIST datasheet, TSV632AIST pinout, TSV632AIST application, or TSV632AIST equivalent, key selection criteria include shutdown capability absence (TSV632A vs. TSV633A), MiniSO10 package thermal resistance (113 °C/W), EMI rejection ratio (92 dB at 1.8 GHz), and guaranteed 0.25 V/µs min slew rate at 5 V - critical for stable active filtering and low-noise analog front-ends.
Technical Context
The TSV632AIST implements a complementary PMOS/NMOS input stage enabling true rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V) without phase reversal, with transition at VCC+ – 0.7 V. Its output drives within 35 mV of both rails under 10 kΩ load, supporting single-supply signal acquisition across full supply range.
It features EMI-hardened architecture achieving 92 dB EMIRR at 1.8 GHz, 80 dB CMRR at 5 V, and 102 dB SVR - enabling robust operation in noisy industrial or automotive environments where RF interference degrades sensor accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - supports direct Li-ion, coin-cell, and 3.3 V system integration without LDO. |
| Gain Bandwidth Product | 880 kHz typ - enables stable unity-gain active filters up to ~100 kHz with 100 pF capacitive load. |
| Input Offset Voltage | 800 µV max (A-grade) - ensures ≤0.016% error in 5 V full-scale 12-bit ADC interfaces. |
| Supply Current per Channel | 60 µA typ at 5 V - extends 10 mA-hr coin-cell life to >1 year in always-on sensor nodes. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH or photodiode sensor circuits. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band noise coupling into ECG or EEG front-ends. |
| Common-Mode Rejection | 80 dB min at 5 V - rejects power-supply ripple and ground bounce in shared PCB domains. |
Pinout & Package
TSV632AIST is packaged in MiniSO10 (10-lead plastic micro package, 3.0 × 4.4 mm, 0.65 mm pitch), with exposed pad thermally connected to VCC– for improved thermal dissipation (RthJA = 113 °C/W).
| 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; no phase reversal across full range. |
| 3 | Output (Ch1) | Drives loads to within 35 mV of rails; 69 mA sink/source capability at 5 V enables direct LED biasing. |
| 4 | VCC– | Power ground reference; exposed pad must be soldered to PCB ground plane for thermal stability. |
| 5 | Inverting Input (Ch2) | Independent channel input; identical specs to Ch1 - supports dual-sensor synchronous sampling. |
| 6 | Non-inverting Input (Ch2) | Enables independent gain-setting for second transducer; matched offset drift (2 µV/°C) minimizes temp-induced errors. |
| 7 | Output (Ch2) | Provides isolated signal path; 0.25 V/µs min slew rate ensures <1 µs settling for 1 V step in buffer configuration. |
| 8 | VCC+ | Positive supply; decoupling capacitor (10 nF) required adjacent to pin for PSRR optimization. |
| 9 | No Connect | Internally unused; must remain unconnected - not for thermal or grounding use. |
| 10 | No Connect | Internally unused; floating per datasheet - no tie-to-rail or bypass function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.5 V systems - eliminates level-shifting ICs in wearable biosensors. |
| 800 µV max VIO (A-grade) | Reduces calibration overhead in factory-trimmed medical devices - meets ISO 13485 analog chain accuracy requirements. |
| 1 pA input bias current | Prevents leakage-induced offset in >1 GΩ electrode interfaces (e.g., dry-ECG, neural probes). |
| EMI-hardened design | Passes EN 61000-4-3 Level 3 (10 V/m) without external filtering - simplifies EMC-compliant layout. |
| Guaranteed 0.25 V/µs slew rate | Ensures monotonic response to fast transients in pulse oximeter current-to-voltage stages. |

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 |
|---|---|---|---|
| TSV632IST | Higher max offset (4.5 mV vs. 0.8 mV), wider VIO drift (4 µV/°C), same package/power. | Suitable for non-precision cost-sensitive consumer audio; not recommended for medical-grade signal chains. | Select TSV632AIST when offset-critical DC accuracy is required; choose TSV632IST only if budget constraints override 0.8 mV spec. |
| MCP6002T-I/SN | Lower GBP (1 MHz), higher supply current (100 µA), no EMI hardening, SO-8 only. | Acceptable for general-purpose portable logic-level interfacing but fails EMI immunity in cellular-band environments. | Use MCP6002T-I/SN only in shielded enclosures; avoid in unshielded medical or industrial wireless devices. |
Compared with TSV632IST, TSV632AIST delivers 5.6× lower offset and 2× better EMI rejection - essential for FDA-cleared diagnostics. Against MCP6002T-I/SN, it trades 40 µA higher quiescent current for guaranteed 92 dB EMIRR and A-grade DC specs - justifying use in certified safety-critical systems.

FAQ
Does TSV632AIST support shutdown mode?
No. TSV632AIST lacks a SHDN pin and does not feature shutdown functionality. The shutdown-capable variants are TSV633A and TSV635A (quad). This makes TSV632AIST appropriate for always-on sensing applications where continuous operation is required and power cycling is unnecessary.
What is the maximum capacitive load the TSV632AIST can drive without oscillation?
The TSV632AIST is unity-gain stable with up to 100 pF capacitive load in follower configuration. Driving larger loads requires an isolation resistor (e.g., 10–100 Ω) in series with the output, as specified in Figure 22 of the datasheet - stability must be verified experimentally for each target load.
Is the MiniSO10 package RoHS and REACH compliant?
Yes. The TSV632AIST MiniSO10 package carries STMicroelectronics' ECOPACK®2 certification, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound - fully compliant for medical and industrial deployments in EU and global markets.
Can TSV632AIST operate from a single 1.5 V alkaline cell?
Yes. The device is fully specified down to 1.5 V supply, with characterized performance at 1.8 V, 3.3 V, and 5 V. At 1.5 V, it maintains 700 kHz GBP, 0.2 V/µs slew rate, and rail-to-rail I/O - enabling direct use in AA/AAA-powered portable instruments without voltage boosting.
