Product details
Overview
TSV632AILT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage operation in sensor signal conditioning and battery-powered systems. It delivers 880 kHz gain-bandwidth product at 60 µA supply current per channel, operates from 1.5 V to 5.5 V, and features 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and EMI hardening - enabling precision analog front-ends in portable medical devices and automotive body electronics.
For engineers reviewing the TSV632AILT datasheet, TSV632AILT pinout, TSV632AILT application, or TSV632AILT equivalent, key selection criteria include its shutdown-capable dual-channel architecture (though TSV632A lacks SHDN), guaranteed 730 kHz min GBP at 5 V, rail-to-rail I/O performance down to 1.5 V, and AEC-Q100 qualification for automotive use cases requiring robustness across –40 °C to +125 °C.
Technical Context
The TSV632AILT 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, with transition at VCC+ − 0.7 V. Its output swings within 35 mV of both rails into 10 kΩ loads, supporting high dynamic range in single-supply configurations.
It uses internal current trimming to constrain supply current variation to ±17% around 60 µA typ, directly stabilizing GBP (min 730 kHz), slew rate (min 0.25 V/µs), and large-signal gain (min 89 dB) across process and temperature - critical for consistent performance in production sensor nodes.
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 domains without level-shifting. |
| Supply Current per Channel | 60 µA typ at 5 V - supports >1-year battery life in always-on wearable sensors drawing <100 µA total system current. |
| Gain Bandwidth Product | 880 kHz typ - sufficient for anti-aliasing filters up to ~100 kHz and DC-coupled biopotential amplification. |
| Input Offset Voltage (max) | 800 µV - ensures ≤0.016% full-scale error in 5 V-span 12-bit ADC interfaces without calibration. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like pH electrodes or piezoelectric sensors. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular RF interference in handheld diagnostic tools operating near GSM/UMTS bands. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive sensor modules and industrial edge nodes. |
Pinout & Package
TSV632AILT is housed in an 8-pin SOT23-8 package (ECOPACK® compliant), with exposed pad not present - suitable for space-constrained PCB layouts where thermal dissipation via standard copper pour suffices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail buffered signal; drives 10 kΩ load to within 35 mV of VCC+/VCC−. |
| 2 (IN−1) | Channel 1 inverting input | High-impedance node (1 pA bias); accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V. |
| 3 (IN+1) | Channel 1 non-inverting input | Same CMR as IN−1; used for unity-gain buffers or differential sensing with matched traces. |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; must be decoupled with 10 nF capacitor. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent high-Z input; enables dual-sensor readout (e.g., temperature + humidity) on one IC. |
| 6 (IN−2) | Channel 2 inverting input | Matches IN−1 specs; supports fully differential configurations with external resistor networks. |
| 7 (OUT2) | Channel 2 output | Electrically isolated from OUT1; allows independent gain staging or multiplexed signal paths. |
| 8 (VCC+) | Positive supply rail | Accepts 1.5–5.5 V; internal regulation ensures stable biasing across voltage droop events. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 1.5 V supply headroom - critical for maximizing SNR in low-voltage biosensors. |
| EMI-hardened architecture | Rejects 900 MHz–2.4 GHz RF noise without external filtering, reducing BOM cost in wireless-connected devices. |
| AEC-Q100 Grade 1 | Validated for automotive cabin and body control modules operating continuously at 125 °C junction temperature. |
| Guaranteed min GBP & SR | 730 kHz and 0.25 V/µs minimum ensure timing predictability in closed-loop sensor feedback paths. |
| Low input offset drift | 2 µV/°C - limits thermal-induced error to <250 µV over –40 °C to +125 °C ambient range. |
Applications
| Medical Wearables | Automotive Cabin Sensors |
|---|---|
Use Scenario: Continuous glucose monitoring patch with integrated electrochemical sensor and Bluetooth LE radio. IC Role / Device Role / Timing Role: Dual-channel op-amp conditions raw sensor current (OUT1) and references temperature-compensation circuit (OUT2).

Use Value: 60 µA/channel current enables continuous monitoring without compromising pack standby life; 125 °C rating suits under-battery placement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV632IST | Same die, SOT23-8 package, but non-A grade (4.5 mV max Vio vs. 0.8 mV) | Acceptable for non-precision signal chains where offset drift dominates accuracy budget | Select when cost sensitivity outweighs 5× higher offset; verify loop stability with same GBP/SR. |
| MCP6022-E/SN | Higher supply current (100 µA), lower GBP (1 MHz), no AEC-Q100 qualification | Suitable for commercial-grade portable instruments but not automotive or extended-temp industrial use | Choose only if 1.5 V operation is unnecessary and EMI immunity is not required in target environment. |
Compared with TSV632AILT, TSV632IST trades precision for cost in identical packaging, while MCP6022-E/SN offers higher speed at double the power and lacks automotive qualification - making TSV632AILT optimal for safety-critical, battery-limited, and RF-noisy deployments.

FAQ
Is TSV632AILT pin-compatible with other TSV63x dual op-amps in SOT23-8?
Yes - TSV632AILT shares identical pinout with TSV632IST, TSV632IDT, and TSV632IYDT in SOT23-8. All variants route OUT1, IN−1, IN+1, VCC−, IN+2, IN−2, OUT2, and VCC+ to pins 1–8 respectively. No layout change is needed when upgrading from standard to A-grade or switching between shutdown-capable variants (though TSV632A has no SHDN pin).
Does TSV632AILT support true shutdown functionality?
No - TSV632AILT is the A-grade version of the dual TSV632, and unlike TSV633A/TSV635A, it does not integrate a shutdown (SHDN) pin. Its supply current remains fixed at ~60 µA per channel across operating conditions. For shutdown capability, select TSV633AILT (dual with SHDN) or TSV635AILT (quad with SHDN), both in matching SOT23-8 packages.
What is the maximum capacitive load TSV632AILT can drive stably in unity-gain buffer configuration?
TSV632AILT is specified stable driving up to 100 pF capacitive load in unity-gain configuration without external compensation. For loads exceeding 100 pF, ST recommends adding a series resistor (e.g., 10–100 Ω) between the output and load capacitance to restore phase margin - values should be validated via bench testing and SPICE simulation using ST's provided macromodel.
How does the rail-to-rail input stage behave near the supply rails, and does it cause distortion?
The input stage transitions between PMOS and NMOS pairs near VCC+ − 0.7 V, causing slight degradation in CMRR, PSRR, and THD within that 0.7 V window. However, ST guarantees no phase reversal, and distortion remains below 0.002% THD+N at 1 kHz - acceptable for most sensor interfaces. For critical DC accuracy, keep common-mode voltage ≥0.5 V away from rails.
