Product details

Overview

TSX711ILT from STMicroelectronics is a precision rail-to-rail input/output CMOS operational amplifier in SOT23-5 package, featuring 200 µV max input offset voltage, 2.7 MHz gain bandwidth product, and operation from 2.7 V to 16 V supply. It delivers 45 mA output drive, 50 pA max input bias current, and supports automotive-grade temperature range (−40 °C to 125 °C), making it suitable for high-impedance sensor interface and battery-powered instrumentation.

For engineers reviewing the TSX711ILT datasheet, TSX711ILT pinout, TSX711ILT application, or TSX711ILT equivalent, key selection criteria include verified rail-to-rail I/O performance at low supply voltages, guaranteed 200 µV offset over temperature, 4 kV HBM ESD tolerance, and validated stability with 100 pF capacitive loads - all confirmed per DS10192 Rev 6.

Technical Context

The TSX711ILT employs a CMOS input stage enabling ultra-low input bias current (≤50 pA) and high input resistance (1 TΩ), critical for interfacing with high-impedance sources like piezoelectric sensors or pH electrodes. Its rail-to-rail input common-mode range extends from (V_CC−) −0.1 V to (V_CC+) +0.1 V, and rail-to-rail output swings within 20 mV of rails under 10 kΩ load at 25 °C.

Internally compensated for unity-gain stability, it achieves 55° phase margin at 16 V supply with 100 pF load, and exhibits 2.5 µV/°C input offset drift - enabling stable DC-coupled signal chains across automotive and industrial environments without recalibration.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	200 µV max at 25 °C - ensures ≤0.5 mV error in 2.5 V full-scale 12-bit DAC buffer applications
Gain Bandwidth Product	2.7 MHz - supports stable closed-loop gain ≥10 up to 270 kHz for active filter design
Supply Voltage Range	2.7 V to 16 V - enables direct use with single-cell Li-ion (3.0–4.2 V) or dual-supply ±8 V systems
Input Bias Current	50 pA max - preserves signal integrity when amplifying nanoamp-level currents from photodiodes or ion-selective electrodes
Output Drive Capability	±45 mA - drives 66 Ω loads at 3 V swing, sufficient for driving ADC reference buffers or low-Z active filters
ESD Tolerance	4 kV HBM - meets ISO 10605 requirements for automotive body electronics mounting without external protection
Operating Temperature	−40 °C to 125 °C - qualified per AEC-Q100 Grade 1, supporting engine control unit (ECU) and battery management sensing

Pinout & Package

SOT23-5 package: compact 2.9 mm × 1.6 mm surface-mount outline with exposed thermal pad (not electrically connected), rated R_thJA = 250 °C/W, suitable for space-constrained PCBs in portable and automotive modules.

Pin/Terminal	Circuit Role	Design Meaning
1 - OUT	Amplifier output	Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±45 mA into resistive loads
2 - VCC−	Negative supply rail	Ground reference for single-supply operation or negative rail in dual-supply configurations
3 - IN+	Non-inverting input	High-impedance CMOS node (1 TΩ); accepts signals from −0.1 V to VCC+ + 0.1 V
4 - VCC+	Positive supply rail	Accepts 2.7–16 V; internal ESD diodes clamp inputs to this rail if exceeded by >0.5 V
5 - IN−	Inverting input	High-impedance CMOS node; matched to IN+ for <200 µV offset and 102 dB CMRR at 4 V supply

Key Features

Feature	Design Value
Rail-to-rail input and output	Enables full dynamic range utilization at 2.7 V supply - e.g., 0–2.7 V DAC output buffering without headroom loss
Low input offset drift	2.5 µV/°C - limits total offset error to <1.25 mV over −40 °C to 125 °C span, critical for thermocouple amplifiers
Unity-gain stable	No external compensation required - simplifies layout for gain-of-1 configurations like voltage followers in sensor front-ends
High CMRR	102 dB at 4 V supply - rejects common-mode noise from shared power rails in multi-channel data acquisition systems
Low quiescent current	800 µA max - allows continuous operation for >1 year on a 200 mAh coin cell in wireless sensor nodes

Applications

Battery-Powered Instrumentation

High-Impedance Sensor Interface

Use Scenario: Portable multimeter front-end amplifying mV-level thermocouple outputs with 16-bit resolution.

IC Role / Device Role / Timing Role: Precision DC-coupled amplifier providing gain and offset correction before SAR ADC sampling.

Use Value: 200 µV offset and 50 pA bias current prevent measurement errors from self-heating or leakage in high-Z probe circuits.

Use Scenario: pH electrode signal conditioning in handheld water quality analyzers.

IC Role / Device Role / Timing Role: Ultra-high-input-impedance buffer isolating glass electrode (≥1 GΩ) from downstream circuitry.

Use Value: 1 TΩ input resistance avoids loading the electrode, preserving accuracy across 0–14 pH range without calibration drift.

DAC Output Buffering

Current Sensing (High/Low Side)

Use Scenario: Driving 12-bit DAC output to actuator control loop in industrial PLC analog output modules.

IC Role / Device Role / Timing Role: Unity-gain voltage follower maintaining linearity and settling time <1 µs for 10 kHz update rates.

Use Value: Rail-to-rail output ensures full 0–5 V DAC range is delivered without clipping, even at 3.3 V supply.

Use Scenario: Bidirectional motor current monitoring in 12 V automotive seat control modules.

IC Role / Device Role / Timing Role: Differential amplifier configured for high-side or low-side shunt measurement with 50 pA input bias.

Use Value: Rail-to-rail input allows accurate sensing near ground (low-side) or near battery rail (high-side) without level-shifting.

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
TSX711AILT	100 µV max input offset (vs. 200 µV), otherwise identical pinout, specs, and package	Better DC accuracy for 16-bit+ data acquisition where offset error must be <0.1 LSB at 5 V full scale	Select when tighter initial offset is required; same footprint and layout - no redesign needed
TSX561IST	Higher GBP (10 MHz), but higher offset (600 µV), lower ESD (2 kV), and no AEC-Q100 qualification	Preferred for AC-coupled, bandwidth-critical applications (e.g., audio preamps), not for automotive or precision DC sensing	Choose only for non-automotive, higher-speed designs where offset and temperature stability are secondary

Compared with TSX711AILT, the TSX711ILT trades 100 µV lower offset for cost sensitivity in volume production; versus TSX561IST, it prioritizes DC precision and automotive robustness over raw speed - making it optimal for sensor signal chains requiring long-term stability and supply flexibility.

FAQ

Is TSX711ILT qualified for automotive applications?

Yes. TSX711ILT is AEC-Q100 Grade 1 qualified (−40 °C to 125 °C), features 4 kV HBM ESD tolerance, and is specified for operation up to 125 °C ambient with full electrical parameters guaranteed - meeting requirements for engine bay and cabin control modules.

Can TSX711ILT drive capacitive loads without oscillation?

Yes. The device is unity-gain stable and maintains ≥50° phase margin with up to 100 pF capacitive load at 16 V supply, as verified in Figure 24 of DS10192. For loads >100 pF, a small series resistor (10–50 Ω) at the output is recommended to ensure stability.

What is the maximum allowable differential input voltage?

The absolute maximum differential input voltage is ±V_CC (per Table 1), but sustained operation above ±0.7 V risks excessive input current due to internal ESD diode conduction. For safe linear operation, keep |V_IN+ − V_IN−| < 0.7 V; higher differentials require external current-limiting resistors per Figure 33.

Does TSX711ILT support dual-supply operation?

Yes. The device operates with split supplies (e.g., ±8 V) as long as total V_CC = V_CC+ − V_CC− remains within 2.7–16 V. Input common-mode range extends 0.1 V beyond each rail, enabling true bipolar signal handling down to −8.1 V and up to +8.1 V with ±8 V supplies.
