Product details

Overview

TSX711AIYLT 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 product, 2.7–16 V supply range, 800 µA max supply current, and automotive-grade operation from –40 °C to 125 °C. It is optimized for high-impedance sensor interface and low-side/high-side current sensing in battery-powered automotive and industrial systems.

For engineers reviewing the TSX711AIYLT datasheet, TSX711AIYLT pinout, TSX711AIYLT application, or TSX711AIYLT equivalent, key selection considerations include its guaranteed 100 µV max V_IO at 25 °C, rail-to-rail I/O performance at 2.7 V supply, 50 pA max input bias current, 4 kV HBM ESD rating, and qualification per AEC-Q100 Grade 1.

Technical Context

The TSX711AIYLT employs a CMOS input stage with PNP-clamped differential pair architecture, enabling rail-to-rail common-mode input range (V_CC– – 0.1 V to V_CC+ + 0.1 V) and low 50 pA max input bias current. Its unity-gain-stable compensation supports stable operation with capacitive loads up to 100 pF.

It delivers 45 mA min output sink/source drive into 2 kΩ at 16 V supply, maintains ≥84 dB CMRR over full temperature range, and achieves 0.6–1.4 V/µs slew rate depending on supply and signal amplitude - all while consuming ≤900 µA across –40 °C to 125 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	100 µV max at 25 °C - enables sub-mV error in precision DC-coupled signal chains without trimming
Gain Bandwidth Product	2.7 MHz - supports stable closed-loop gain ≥10 up to ~250 kHz with adequate phase margin
Supply Voltage Range	2.7 V to 16 V - operates from single-cell Li-ion (3.0 V) to 12 V automotive rails without level-shifting
Input Bias Current	50 pA max - preserves signal integrity in >100 MΩ sensor interfaces (e.g., pH, piezoelectric)
Output Drive Capability	45 mA min sink/source at 16 V - drives 2 kΩ loads directly, eliminating need for external buffers in DAC output stages
ESD Tolerance	4 kV HBM - meets automotive board-level robustness requirements without additional protection circuitry
Operating Temperature	–40 °C to 125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications

Pinout & Package

SOT23-5 surface-mount package with 1.3 mm × 2.3 mm footprint, 0.95 mm height, and 0.95 mm lead pitch. RoHS-compliant, halogen-free, and qualified for reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning

3 (IN+)	Non-inverting Input	CMOS input with 1 TΩ typical R_IN; protected by series 1 kΩ resistor + clamp diodes
4 (V_CC+)	Positive Supply Rail	Accepts 2.7–16 V; internal regulation ensures stable biasing across full range
5 (IN–)	Inverting Input	Matched to IN+ in offset and bias; same ESD protection structure and 12.5 pF C_IN

Key Features

Feature	Design Value

IC Role / Device Role / Timing Role: Transimpedance amplifier converting sensor current to voltage with minimal input loading and drift.

Use Value: 50 pA max I_IB and 100 µV max V_IO ensure <10 µV baseline error over temperature, enabling ±0.5% gas concentration accuracy.

Use Scenario: Medical ECG front-end acquiring microvolt-level biopotentials from dry electrodes with >1 GΩ contact impedance.

IC Role / Device Role / Timing Role: First-stage instrumentation amplifier driver with rail-to-rail input to maximize ADC dynamic range.

Use Value: Rail-to-rail input extends usable common-mode range to ±0.1 V beyond rails, capturing full electrode offset swing without clipping.

Current Sensing (High/Low Side)

DAC Buffer

Use Scenario: Bidirectional motor current monitoring in 12 V automotive HVAC blower module with shunt placed on high-side or low-side.

IC Role / Device Role / Timing Role: Difference amplifier or current-sense amplifier configured for unidirectional/bidirectional sensing.

Use Value: Rail-to-rail I/O allows accurate sensing down to 0 V common-mode (low-side) or up to 12 V (high-side) without external level shifters.

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
TSX711IYLT	200 µV max V_IO (vs. 100 µV), otherwise identical pinout, specs, and qualification	Acceptable where <200 µV offset suffices; lower cost for non-critical DC accuracy	Select when system-level offset budget allows 2× higher V_IO and cost sensitivity outweighs precision gain
TSX561IST	Higher GBP (9 MHz), but 500 µV max V_IO, 100 nA I_IB, not AEC-Q100 qualified	Preferred for AC-coupled, bandwidth-critical apps (e.g., active filters); unsuitable for automotive or ultra-low-bias use	Choose only for non-automotive, higher-speed designs where offset and bias current are secondary to bandwidth

Compared with TSX711IYLT, TSX711AIYLT provides tighter offset control critical for DC-coupled measurement, while TSX561IST trades precision for speed and lacks automotive qualification - making TSX711AIYLT the sole choice for AEC-Q100-compliant, low-drift sensor signal conditioning.

FAQ

Is TSX711AIYLT pin-compatible with TSX711IYLT?

Yes - both share identical SOT23-5 pinout (OUT, V_CC–, IN+, V_CC+, IN–), same footprint, and identical absolute maximum ratings. The only functional difference is the guaranteed input offset voltage: 100 µV max for TSX711AIYLT versus 200 µV max for TSX711IYLT. No PCB or schematic changes are required for substitution.

What is the maximum capacitive load TSX711AIYLT can drive while remaining stable?

TSX711AIYLT is unity-gain stable with up to 100 pF capacitive load, as verified in DS10192 Figure 26 and confirmed by ≥50° phase margin in Table 3. For loads >100 pF, a series isolation resistor (typically 10–100 Ω) between output and capacitance is required to maintain stability without degrading step response.

Does TSX711AIYLT support true single-supply operation down to 2.7 V?

Yes - it operates with V_CC– = 0 V and V_CC+ = 2.7 V, delivering rail-to-rail input (–0.1 V to 2.8 V) and output (within 40 mV of each rail at 10 kΩ). Electrical characteristics including GBP, V_IO, and I_CC are fully specified at 4 V, but functional performance is validated from 2.7 V per Section 5.1 of DS10192.

How does the input protection structure affect design-in for overvoltage conditions?

The inputs feature integrated 1 kΩ series resistors and back-to-back PNP clamps to V_CC+/V_CC–. If input voltage exceeds either rail by >0.5 V, clamp conduction occurs. To prevent damage, external series resistance must limit current to ≤10 mA - e.g., ≥220 Ω for a 2.7 V supply with 5 V transient, as shown in Figure 33 of DS10192.
