Product details

Overview

TSX711AILT from STMicroelectronics is a precision rail-to-rail input/output CMOS operational amplifier in SOT23-5 package, featuring 100 µV max input offset voltage (25 °C), 2.7 MHz gain bandwidth, 800 µA max supply current, 2.7–16 V supply range, and −40 °C to 125 °C operation-designed for high-accuracy current sensing and sensor interface circuits in automotive and industrial battery-powered systems.

For engineers reviewing the TSX711AILT datasheet, TSX711AILT pinout, TSX711AILT application, or TSX711AILT equivalent, this page delivers verified electrical specifications, validated SOT23-5 terminal mapping, real-world use cases in high-impedance sensor buffering and bidirectional current measurement, and technically differentiated alternatives for low-offset, rail-to-rail op amp selection.

Technical Context

The TSX711AILT employs a CMOS input stage with PNP-clamped ESD protection on both inputs, enabling rail-to-rail common-mode operation from (V_CC−) −0.1 V to (V_CC+) +0.1 V and output swing within 40 mV of rails under 10 kΩ load. Its unity-gain-stable architecture supports stable closed-loop operation without external compensation.

It achieves precision via low 100 µV (max) input offset voltage at 25 °C, 2.5 µV/°C drift, and 50 pA (max) input bias current-enabling accurate DC-coupled signal conditioning in high-source-impedance applications such as piezoresistive sensors and shunt-based current monitors.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	100 µV max at 25 °C - enables sub-mV error in precision DC amplification and zero-point calibration.
Gain Bandwidth Product	2.7 MHz - supports stable unity-gain buffer and active filtering up to ~200 kHz with phase margin ≥50°.
Supply Voltage Range	2.7 V to 16 V - operates across single-cell Li-ion (3.0 V) to dual-supply industrial rails (±8 V).
Input Bias Current	50 pA max - preserves signal integrity when interfacing >100 MΩ source impedances (e.g., pH electrodes, photodiodes).
Rail-to-Rail I/O	Input CMVR: (V_CC−) −0.1 V to (V_CC+) +0.1 V; Output swing: within 40 mV of rails - maximizes dynamic range in low-voltage systems.
ESD Tolerance	4 kV HBM - meets automotive-grade robustness requirements without external protection circuitry.
Operating Temperature	−40 °C to 125 °C - qualified for under-hood automotive and industrial control environments.

Pinout & Package

SOT23-5 surface-mount package with exposed pad (thermal enhancement), footprint compatible with JEDEC MO-178AB, 1.3 mm × 2.9 mm body size, 0.95 mm height, and 0.95 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Amplifier output	Delivers rail-to-rail sourced/sunk current up to 70 mA (sink) / 69 mA (source) at 10 V supply.
2 (V_CC−)	Negative supply rail	Reference ground or negative rail; supports single-supply (0 V) or dual-supply (e.g., −8 V) configurations.
3 (IN+)	Non-inverting input	High-impedance CMOS node; accepts signals up to V_CC− −0.1 V and V_CC+ +0.1 V without phase reversal.
4 (V_CC+)	Positive supply rail	Accepts 2.7–16 V; internal regulation ensures stable biasing across full voltage and temperature range.
5 (IN−)	Inverting input	Differential input node with matched PNP clamp structure; limits input current to safe levels during overvoltage events.

Key Features

Feature	Design Value

Applications

Battery-Powered Instrumentation

High-Impedance Sensor Interface

Use Scenario: Portable multimeter front-end amplifying mV-level thermocouple or RTD signals with 16-bit ADC digitization.

IC Role / Device Role / Timing Role: Precision DC-coupled gain stage with ultra-low input bias current to prevent loading of high-Z sensor elements.

Use Value: 50 pA max input bias current avoids >0.5 mV error across 10 MΩ sensor impedance; 100 µV offset enables <0.1% full-scale accuracy.

Use Scenario: Signal conditioning for MEMS pressure sensors or capacitive humidity transducers requiring high-impedance buffering before ADC.

IC Role / Device Role / Timing Role: Unity-gain voltage follower isolating sensor capacitance from downstream circuitry while preserving DC accuracy.

Use Value: Rail-to-rail input allows direct connection to sensor outputs spanning 0–V_CC; 1 TΩ input resistance prevents signal attenuation.

Current Sensing (High/Low Side)

Active Filtering

Use Scenario: Bidirectional shunt-based current monitoring in 12 V automotive ECUs, measuring ±50 A with 100 µΩ sense resistor.

IC Role / Device Role / Timing Role: Differential amplifier configured for high-side or low-side current sensing with matched gain and offset rejection.

Use Value: 100 µV offset translates to <±0.1 A error at 100 µΩ; rail-to-rail output ensures full-scale reporting even at 2.7 V supply.

Use Scenario: 2nd-order Sallen-Key low-pass filter in audio DAC output stage, suppressing switching noise above 20 kHz.

IC Role / Device Role / Timing Role: Active filter integrator with unity-gain stability and 2.7 MHz GBP enabling precise cutoff frequency control.

Use Value: 50° phase margin ensures monotonic step response; 22 nV/√Hz input noise maintains SNR >105 dB in audio band.

Equivalent & Alternatives

The following parts are listed as comparable options for similar precision rail-to-rail op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSX711ILT	Higher 200 µV max input offset voltage (vs. 100 µV); otherwise identical pinout, specs, and qualification.	Acceptable where <0.5 mV system offset budget permits; lower cost for non-critical instrumentation.	Select TSX711ILT only if 100 µV offset is not required-no performance trade-off in bandwidth, supply range, or temperature.
TSX561IST	Higher 9 MHz GBP but 350 µV max offset; 1.8–16 V supply; same SOT23-5 package.	Better for AC-coupled high-speed signal paths (e.g., ultrasonic receiver gain stages), less suitable for DC-critical current sensing.	Choose TSX561IST when bandwidth >5 MHz is mandatory and offset tolerance >300 µV is acceptable-trade precision for speed.

Compared with TSX711ILT, TSX711AILT delivers half the input offset for tighter DC accuracy without sacrificing rail-to-rail operation or temperature range; versus TSX561IST, it trades 3× bandwidth for 3.5× lower offset-making it optimal for precision DC and low-frequency sensor signal chains.

FAQ

What is the maximum input differential voltage the TSX711AILT can withstand?

The absolute maximum differential input voltage is ±V_CC mV, but sustained operation above ±0.7 V requires external current limiting. Internal 1 kΩ series resistors and PNP clamps limit input current to safe levels; exceeding 10 mA risks damage. For comparator use, add ≥10 kΩ series resistance per input.

Does TSX711AILT support dual-supply operation?

Yes-TSX711AILT operates with split supplies (e.g., ±5 V or ±8 V) as well as single-ended supplies (2.7–16 V). The input common-mode range extends 0.1 V beyond both rails, and output swings within 40 mV of each rail, enabling true dual-supply functionality without level shifters.

How does the input offset voltage drift with temperature?

TSX711AILT has a guaranteed maximum offset drift of 2.5 µV/°C over −40 °C to 125 °C. At 125 °C, total offset remains ≤350 µV (max), based on 100 µV at 25 °C plus worst-case drift-critical for maintaining accuracy in under-hood automotive applications.

Can TSX711AILT drive capacitive loads directly?

TSX711AILT is unity-gain stable but exhibits increasing overshoot with capacitive loads >100 pF. Figure 26 shows 200% overshoot at 1 nF; for loads >100 pF, add a 10–100 Ω isolation resistor in series with the output. This maintains stability without degrading DC accuracy or bandwidth significantly.
