Product details
Overview
TSB712IYDT from STMicroelectronics is a dual-channel, rail-to-rail input/output precision operational amplifier optimized for high-accuracy current sensing and industrial signal conditioning. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, 300 µV max input offset voltage at 25 °C, and operates from 2.7 V to 36 V single supply (±1.35 V to ±18 V dual). It is widely used in motor control feedback loops and Hall effect sensor interfaces where wide common-mode range and low noise (12 nV/√Hz) are critical.
For engineers reviewing the TSB712IYDT datasheet, TSB712IYDT pinout, TSB712IYDT application, or TSB712IYDT equivalent, key selection criteria include its dual-channel SO8 package, guaranteed rail-to-rail operation up to 125 °C, integrated EMI filter, 2 kV HBM ESD rating, and compatibility with high-side/low-side current shunt configurations requiring <1 mV offset drift over temperature.
Technical Context
The TSB712IYDT employs a complementary bipolar input stage enabling true rail-to-rail input operation from VCC− to (VCC+)+0.1 V, with optimal CMRR performance maintained across VCC− to (VCC+)−1.5 V. Its architecture avoids phase reversal within absolute maximum common-mode limits (VCC− −0.2 V to VCC+ +0.2 V).
It features an internal EMI filter that suppresses RF rectification-induced offset shifts, validated per EMIRR testing. The device supports stable unity-gain operation with ≥45° phase margin at 10 kΩ/100 pF load and drives capacitive loads up to 100 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz - enables stable closed-loop operation up to ~500 kHz at G = +10 with <0.1 dB gain flatness. |
| Slew Rate | 3 V/µs - supports 10 Vpp output at 48 kHz without slewing distortion in unity-gain buffer applications. |
| Input Offset Voltage | ±300 µV max at 25 °C - ensures ≤0.3 mV error in 100 mΩ shunt-based 10 A current sense at 25 °C. |
| Supply Voltage Range | 2.7 V to 36 V - allows direct interface with 24 V industrial buses and 3.3 V/5 V microcontrollers without level-shifting. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - contributes <1.2 µVrms integrated noise in 100 kHz bandwidth, critical for strain gauge amplification. |
| Common-Mode Rejection | 115 dB min (VCC− to VCC+−1.5 V) - rejects >10⁵:1 of common-mode interference in high-side sensing configurations. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial PLC environments without derating. |
Pinout & Package
TSB712IYDT is housed in a MiniSO-8 (SO8) package with exposed pad for thermal enhancement, compatible with standard SOIC-8 footprints and reflow profiles. Pin 1 is OUT1; pin 4 is VCC−; pin 8 is VCC+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of channel 1 - rail-to-rail swing supports full-scale ADC input drive without clipping. |
| 2 | IN1− | Inverting input of channel 1 - matched to IN1+ for differential gain accuracy in instrumentation amps. |
| 3 | IN1+ | Non-inverting input of channel 1 - accepts signals down to VCC−, enabling true ground-referenced sensing. |
| 4 | VCC− | Negative supply terminal - must be connected to system ground or negative rail; decoupling capacitor required. |
| 5 | IN2+ | Non-inverting input of channel 2 - electrically isolated from channel 1; supports independent dual-sensor conditioning. |
| 6 | IN2− | Inverting input of channel 2 - maintains same bias current matching as channel 1 for consistent common-mode rejection. |
| 7 | OUT2 | Output of channel 2 - independently buffered; no crosstalk >125 dB at 1 kHz ensures signal integrity in multi-channel systems. |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V transient; requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends to VCC+ +0.1 V and output swings within 120 mV of rails at 15 mA load - enables direct interfacing with low-voltage ADCs and logic. |
| Integrated EMI Filter | On-die RC network suppresses RF rectification up to 1 GHz - eliminates need for external ferrite beads in noisy motor drive environments. |
| Automotive-grade Option | TSB712IYDT meets AEC-Q100 Grade 1 (−40 °C to +125 °C) with enhanced latch-up immunity (100 mA) and 2 kV HBM ESD - suitable for engine control and battery monitoring. |
| Low Input Bias Current | Max ±900 nA over temperature - minimizes voltage error across high-impedance sensor bridges (e.g., 10 kΩ strain gauges). |
| Stable Capacitive Load Drive | Guaranteed stability with 100 pF load - permits direct connection to long PCB traces or shielded cables without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB712IYDT | 6 MHz GBW, 3 V/µs SR, ±300 µV Vos max, MiniSO-8 | Optimized for high-voltage industrial sensing with EMI filter | Preferred for 24 V systems requiring automotive-grade reliability and low-noise current sensing. |
| OPA2333AIDR | 350 kHz GBW, 0.16 V/µs SR, ±2 µV Vos max, SOIC-8 | Chopper-stabilized zero-drift architecture; higher DC precision but lower speed | Select when ultra-low drift (<0.02 µV/°C) dominates over bandwidth in DC-coupled sensor nodes. |
| AD8602ARZ | 9.5 MHz GBW, 5 V/µs SR, ±600 µV Vos max, SOIC-8 | Higher bandwidth/slew but no integrated EMI filter; not AEC-Q100 qualified | Choose for high-speed data acquisition where EMI immunity is managed externally and automotive qualification is unnecessary. |
Compared with OPA2333AIDR, TSB712IYDT offers 17× higher bandwidth and integrated EMI rejection but trades off chopper-level DC precision; versus AD8602ARZ, it provides superior ESD robustness (2 kV vs. 1.5 kV), automotive qualification, and guaranteed rail-to-rail operation at 125 °C.

FAQ
What is the maximum capacitive load the TSB712IYDT can drive without instability?
The TSB712IYDT is specified to remain stable with capacitive loads up to 100 pF when driving a 10 kΩ load, as verified by phase margin ≥45° at unity gain. For loads exceeding 100 pF, external series resistance (≥10 Ω) at the output is recommended to maintain stability, particularly in motor control feedback paths with long cable runs.
Does the TSB712IYDT support single-supply operation below 3 V?
Yes - the TSB712IYDT is fully specified down to 2.7 V single supply, with rail-to-rail input extending to VCC− and output swing within 120 mV of VCC− at 2 mA load. At 2.7 V, GBP remains ≥4.5 MHz and Vos stays within ±800 µV, making it suitable for battery-powered instrumentation with LiFePO₄ (2.8–3.6 V) or 3-cell alkaline supplies.
How does the integrated EMI filter function, and what frequency range does it cover?
The integrated EMI filter is a monolithic RC network on the input stage that attenuates RF interference above 10 MHz, preventing rectification-induced offset shifts. It is effective against GSM/ISM band noise (800 MHz–2.4 GHz) and switching regulator harmonics, validated by EMIRR >80 dB at 900 MHz - eliminating need for external RFI filters in motor drive PCB layouts.
Can the TSB712IYDT be used in comparator mode despite being an op amp?
While functional as a comparator, the TSB712IYDT lacks internal hysteresis and has typical propagation delay >1 µs in open-loop configuration. Its inputs tolerate differential voltages only up to ±2 V; exceeding this risks damage unless current-limited to ≤10 mA. For reliable comparator use, external hysteresis and clamping diodes are required - dedicated comparators like TS882 are preferred for timing-critical applications.
