Product details
Overview
TSX711IYLT 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 TSX711IYLT datasheet, TSX711IYLT pinout, TSX711IYLT application, or TSX711IYLT equivalent, key selection criteria include its low-offset stability across voltage/temperature, rail-to-rail dynamic range at 2.7 V, ESD-hardened (4 kV HBM) design, and validated performance in current-sensing and DAC buffering circuits.
Technical Context
The TSX711IYLT employs a CMOS input stage with PNP-clamped differential pair architecture, enabling rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V) and supporting full-scale signal acquisition near supply rails. Its unity-gain-stable compensation ensures stable operation with capacitive loads up to 100 pF without external compensation.
It integrates internal ESD protection diodes on both inputs referenced to VCC+ and VCC−, requiring external series resistance if input voltage exceeds rails by >0.5 V. The device achieves 102 dB typical CMRR at 4 V supply and maintains ≥94 dB CMRR across 4–16 V, critical for precision DC-coupled measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 200 µV max at 25 °C - enables <0.02% error in 10 mV full-scale sensor signals without trimming |
| Gain Bandwidth Product | 2.7 MHz - supports stable closed-loop gain of 10 up to 270 kHz for anti-aliasing filter design |
| Supply Voltage Range | 2.7 V to 16 V - operates directly from single-cell Li-ion (3.0–4.2 V) or industrial 12 V rails |
| Input Bias Current | 50 pA max - preserves signal integrity in >100 MΩ source impedance applications (e.g., pH electrodes) |
| Output Drive Capability | ±45 mA - drives 2 kΩ loads to rail with <50 mV saturation at 4 V supply, enabling direct ADC driver use |
| ESD Tolerance | 4 kV HBM - meets IEC 61000-4-2 Level 2 for board-level robustness in automotive ECUs |
| Operating Temperature | −40 °C to 125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive sensor signal conditioning |
Pinout & Package

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 buffer 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 |
|---|---|---|---|
| TSX711AIDT | 100 µV max Vio (vs. 200 µV), same SOT23-5 package and specs otherwise | Better DC accuracy required in high-resolution weigh scale front-ends | Select when <100 µV offset is mandatory; identical footprint and layout compatibility |
| TSX561IST | 9 MHz GBW, 1.1 mA ICC, 1.8–16 V supply - higher speed but 3× higher quiescent current | Requires faster settling in active filter stages with >500 kHz cutoff | Choose only if bandwidth >4 MHz is needed; avoid for battery life-critical designs |
Compared with TSX711IYLT, TSX711AIDT improves DC precision without trade-offs, while TSX561IST sacrifices power efficiency for bandwidth - making TSX711IYLT optimal for low-power, high-accuracy sensor signal chains where 2.7 MHz suffices.

FAQ
What is the maximum capacitive load the TSX711IYLT can drive without oscillation?
The TSX711IYLT is unity-gain stable and characterized for stable operation with up to 100 pF capacitive load at the output, as verified in Figure 26 of DS10192 Rev 6. For loads exceeding 100 pF, a series isolation resistor (≥10 Ω) between amplifier output and capacitor is required to maintain phase margin >50°.
Does TSX711IYLT support true single-supply operation with input voltages down to ground?
Yes - its rail-to-rail input stage allows common-mode voltage from VCC− − 0.1 V to VCC+ + 0.1 V. With VCC− = 0 V (ground), inputs operate from −0.1 V to VCC+ + 0.1 V, enabling direct interfacing with grounded sensors and 0 V-referenced DACs without level-shifting circuitry.
How does the input ESD protection affect external circuit design?
The TSX711IYLT includes internal ESD diodes from each input to VCC+ and VCC−. If input voltage exceeds either rail by >0.5 V, these diodes conduct. To prevent damage, external series resistance must limit current to ≤10 mA - e.g., a 1 kΩ resistor protects against ±5 V transients on a 3.3 V system.
Is TSX711IYLT pin-compatible with other op amps in SOT23-5 package?
No - the TSX711IYLT uses a non-standard pinout: Pin 1 = OUT, Pin 2 = VCC−, Pin 3 = IN+, Pin 4 = VCC+, Pin 5 = IN−. This differs from industry-standard SOIC-5 or generic SOT23-5 op amps (e.g., MCP6001, LMV321), requiring dedicated PCB layout and not supporting drop-in replacement.
