Product details
Overview
TSX712IYDT from STMicroelectronics is a dual, precision rail-to-rail input/output CMOS operational amplifier in MiniSO-8 package, delivering 200 µV max input offset voltage, 2.7 MHz gain bandwidth, and operation from 2.7 V to 16 V supply. It supports high-impedance sensor interface and bidirectional current sensing (high-side and low-side) in automotive and industrial instrumentation.
For engineers reviewing the TSX712IYDT datasheet, TSX712IYDT pinout, TSX712IYDT application, or TSX712IYDT equivalent, this page provides verified electrical specifications, MiniSO-8 terminal mapping, real-world use cases for precision analog signal conditioning, and validated alternative parts with documented functional trade-offs.
Technical Context
The TSX712 implements a complementary input stage enabling true rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V) and rail-to-rail output swing (within 40 mV of rails at 10 kΩ load). Its CMOS architecture delivers 50 pA max input bias current and 1 TΩ input resistance - critical for high-Z sensor buffering and DAC output driving.
It features unity-gain stability with 50°–55° phase margin across 2.7–16 V supply, 22 nV/√Hz input voltage noise at 1 kHz, and 0.0002% THD+N at 1 kHz with 5 VPP output - confirming suitability for precision active filtering and low-distortion signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 200 µV max at 25 °C - enables sub-mV accuracy in 12-bit+ measurement systems without trimming |
| Gain bandwidth product | 2.7 MHz - supports stable closed-loop operation up to ~200 kHz with gain ≥ 10 |
| Supply voltage range | 2.7 V to 16 V - interoperable with single-supply 3.3 V, 5 V, 12 V, and 15 V industrial rails |
| Input bias current | 50 pA max - preserves signal integrity when interfacing >100 MΩ sensors (e.g., pH, piezoelectric) |
| Output drive capability | ±35 mA min sink/source at 10 V - drives 2 kΩ loads directly, eliminating external buffers in current-sense amplifiers |
| Common-mode rejection | 98 dB min (TSX712, Vicm = –0.1 to 8 V) - rejects power supply ripple and shared-noise coupling in noisy environments |
| ESD tolerance | 4 kV HBM - meets automotive AEC-Q100 stress requirements for robustness in vehicle ECUs |
Pinout & Package
TSX712IYDT is housed in MiniSO-8 (SOIC-8 narrow) package, 3.9 mm × 4.9 mm, 1.27 mm pitch, with exposed pad for thermal enhancement. Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Rail-to-rail output capable of sourcing/sinking ≥35 mA; settles within 1 µs for 1 V step |
| 2 (IN1−) | Amplifier 1 inverting input | High-impedance node (1 TΩ); accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V |
| 3 (IN1+) | Amplifier 1 non-inverting input | Matches IN1− in offset and bias; used for unity-gain buffer or differential pair front-end |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; supports true 0 V input common-mode |
| 5 (VCC+) | Positive supply rail | Accepts 2.7–16 V; PSRR ≥ 100 dB ensures immunity to supply noise up to 100 kHz |
| 6 (IN2−) | Amplifier 2 inverting input | Electrically isolated from Amp1; channel separation ≥ 100 dB @ 1 kHz prevents crosstalk in dual-path designs |
| 7 (IN2+) | Amplifier 2 non-inverting input | Independent high-Z input; enables dual-channel instrumentation amplifier configuration |
| 8 (OUT2) | Amplifier 2 output | Matched performance to OUT1; allows simultaneous signal conditioning and reference buffering |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 0.1 V beyond rails; output swings to within 40 mV of VCC+/VCC− - maximizes dynamic range at low supply voltages |
| Low offset drift | 2.5 µV/°C max - limits temperature-induced error to <0.5 mV over –40 °C to 125 °C full range |
| High ESD robustness | 4 kV HBM - eliminates need for external TVS diodes in board-level ESD protection schemes |
| Automotive qualified | AEC-Q100 Grade 1 (–40 °C to 125 °C) - certified for engine control, battery management, and ADAS sensor interfaces |
| Low quiescent current | 900 µA max per amplifier - enables always-on monitoring in battery-powered telematics and portable diagnostics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSX712IDT | Same die, SO-8 package (5.0 mm × 4.0 mm); 125 °C max operating temp; no exposed thermal pad | Limited thermal dissipation in high-power-density layouts; less suitable for sustained 125 °C ambient | Select when board space allows larger SO-8 footprint and thermal load is <150 mW |
| TSX562IYDT | Higher GBP (9 MHz), higher supply current (1.4 mA), lower offset (150 µV), but only 6 V max supply | Not usable in 12 V/16 V systems; superior speed for fast-settling filters but incompatible with wide-supply designs | Choose only for 3.3 V/5 V applications requiring >5× bandwidth and tighter offset spec |
Compared with TSX712IYDT, TSX712IDT trades thermal performance for legacy SO-8 compatibility, while TSX562IYDT offers speed and offset advantages at the cost of supply voltage range and power efficiency - making TSX712IYDT the optimal balance for automotive and industrial dual-rail systems.

FAQ
What is the maximum capacitive load the TSX712IYDT can drive stably?
The TSX712IYDT remains unity-gain stable with up to 100 pF capacitive load, as confirmed by phase margin ≥50° in datasheet Figure 23–24. For loads >100 pF, a series resistor (≥100 Ω) between output and capacitance is required to maintain stability - verified via overshoot measurements in Figure 26 showing <5% overshoot at 100 pF and 2.7 V supply.
Does TSX712IYDT support single-supply operation down to 2.7 V with rail-to-rail input?
Yes. The TSX712IYDT guarantees rail-to-rail input operation from (VCC−) − 0.1 V to (VCC+) + 0.1 V across the full 2.7–16 V supply range and –40 °C to 125 °C temperature range. At 2.7 V supply, common-mode range spans –0.1 V to +2.8 V, enabling direct interfacing with 0 V-referenced sensors and DACs.
How does the channel separation performance impact dual-amplifier applications?
TSX712IYDT achieves ≥100 dB channel separation at 1 kHz (Figure 32), meaning crosstalk between Amplifier 1 and Amplifier 2 is below –100 dB. This enables independent signal paths - e.g., one channel for sensor signal, another for reference - without measurable interference, critical for precision ratiometric measurements and dual-path active filters.
Is the exposed thermal pad on the MiniSO-8 package electrically connected?
No. The exposed pad on TSX712IYDT's MiniSO-8 package is a thermal pad only, not electrically connected to any internal node. It must be soldered to a PCB copper pour for thermal conduction but may remain floating electrically - confirmed in ST's package drawing and layout guidelines (AN4969).
