Product details
Overview
TSV631IYLT 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 quiescent current (5 V), supports 1.5–5.5 V supply, achieves ±35 mV output swing to rails with 1 pA input bias current, and operates across –40 °C to 125 °C - enabling use in automotive sensor front-ends and portable medical monitors.
For engineers reviewing the TSV631IYLT datasheet, TSV631IYLT pinout, TSV631IYLT application, or TSV631IYLT equivalent, key selection criteria include its 500 µV max offset (A-grade), shutdown current of 5 nA, unity-gain stability with 100 pF capacitive load, and compatibility with SC70-5 and SOT23-5 packages for space-constrained PCB layouts.
Technical Context
The TSV631IYLT 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 internal trimming ensures tight dispersion of DC/AC parameters: supply current variation is limited to ±17 %, and minimum GBP (730 kHz) and slew rate (0.25 V/µs) are guaranteed across temperature.
It features unity-gain stable architecture with 50° phase margin into 2 kΩ//100 pF loads, and includes robust ESD protection (4 kV HBM). The device lacks a shutdown pin - distinguishing it from the TSV630 variant - and is specified for single-supply operation only, with no dual-rail support or internal charge pump.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration with Li-ion, coin-cell, and 3.3 V logic rails without LDO. |
| Quiescent Current | 60 µA typ at 5 V - extends battery life in always-on sensor nodes beyond 10 years on CR2032. |
| Gain Bandwidth Product | 880 kHz typ - supports anti-aliasing filtering up to ~140 kHz with ≥6 dB gain margin. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH or photodiode interfaces. |
| Output Swing | Within 35 mV of rails (RL = 10 kΩ) - maximizes dynamic range in 1.8 V ADC driver applications. |
| Offset Voltage | 3 mV max (standard grade), 500 µV max (A-grade) - meets 12-bit accuracy requirement without calibration. |
| CMRR | 80 dB min at 5 V - rejects common-mode noise in single-ended industrial transducer outputs. |
Pinout & Package
TSV631IYLT is packaged in SC70-5 (SOT323-5), a 5-pin, 1.25 mm × 1.65 mm surface-mount package with exposed pad option. Pin 1 is marked by dot; pin 3 is VCC, pin 2 is inverting input, pin 5 is non-inverting input, pin 4 is output, and pin 1 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference node for all internal biasing; must be low-impedance connection to minimize PSRR degradation. |
| 2 | Inverting Input (–) | Differential input node; high-impedance (1 pA bias) - requires guard ring in >100 MΩ sensor interfaces. |
| 3 | VCC | Positive supply rail; decoupling capacitor (10 nF) required within 1 mm for stability at 880 kHz. |
| 4 | Output | Class AB rail-to-rail output stage; capable of sourcing/sinking 63 mA - drives 10 kΩ loads to full scale. |
| 5 | Non-inverting Input (+) | Differential input node; matched to pin 2 for <2 µV/°C drift - critical for precision instrumentation amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal utilization in 1.8 V systems - eliminates level-shifting circuitry in wearable biosensors. |
| Low input bias current (1 pA) | Permits use with >1 GΩ source impedances - essential for electrochemical sensor front-ends and piezoelectric signal chains. |
| Unity-gain stable (100 pF load) | Eliminates need for external compensation in voltage-follower configurations - reduces BOM count in active filters. |
| Extended temperature range (–40 °C to 125 °C) | Qualified for under-hood automotive and industrial motor control environments - no derating required at max ambient. |
| Tight parameter dispersion (±17 % ICC) | Ensures consistent loop response across production batches - simplifies closed-loop tuning in factory-calibrated devices. |
Applications
| Medical Pulse Oximetry | Automotive Cabin Air Quality Sensor |

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 |
|---|---|---|---|
| TSV631AIDT | Same SC70-5 package; 500 µV max offset (vs. 3 mV), same 60 µA ICC and 880 kHz GBP. | Required where 12-bit+ DC accuracy is mandatory without system calibration. | Select when offset drift and long-term stability outweigh cost sensitivity. |
| MCP6001UT-E/OT | Higher 100 µA ICC, lower 1 MHz GBP, 2 mV offset, SOT23-5 package - not AEC-Q100 qualified. | Suitable for consumer wearables but not automotive or medical certified designs. | Choose only for cost-driven, non-safety-critical applications with relaxed DC specs. |
Compared with TSV631IYLT, the TSV631AIDT offers superior DC precision at identical power and speed, while the MCP6001UT-E/OT trades offset and qualification for broader distributor availability - making the TSV631IYLT optimal for AEC-Q100-compliant, battery-limited industrial sensing.

FAQ
Is TSV631IYLT pin-compatible with TSV630IYLT?
No. TSV631IYLT has 5 pins (SC70-5) and no shutdown function, while TSV630IYLT is a 6-pin SC70-6 device with SHDN pin. Their pinouts differ fundamentally: TSV631 uses pins 1–5 for GND, –IN, VCC, OUT, +IN; TSV630 adds SHDN on pin 6. Board redesign is required for substitution.
Does TSV631IYLT support dual-supply operation?
No. TSV631IYLT is specified exclusively for single-supply operation from 1.5 V to 5.5 V. It lacks symmetric rail capability or dual-supply pinout. Its input common-mode range extends 0.1 V beyond VCC– (GND), but it cannot accept negative input voltages or operate with VCC– < 0 V.
What is the maximum capacitive load TSV631IYLT can drive without oscillation?
TSV631IYLT is unity-gain stable up to 100 pF with resistive load ≥2 kΩ. Driving >100 pF requires an in-series resistor (RISO) at the output - e.g., 10 Ω for 330 pF - per Figure 23 in the datasheet. Stability must be verified experimentally, as PCB layout parasitics affect phase margin.
How does TSV631IYLT's 1 pA input bias current impact high-impedance sensor interfaces?
At 1 pA typical input bias, TSV631IYLT introduces ≤1 µV error across a 1 GΩ source impedance - preserving signal fidelity in pH electrodes, photodiodes, and piezoelectric sensors. This enables direct coupling without guard traces or bias-current cancellation networks in most precision applications.
