Product details
Overview
TSB712AIYST from STMicroelectronics is a dual-channel, rail-to-rail input/output precision operational amplifier designed for high-accuracy signal conditioning in industrial and automotive systems. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, and ≤300 µV max input offset voltage at 25 °C, operating from 2.7 V to 36 V single supply (±1.35 V to ±18 V dual). It is used in high-side/low-side current sensing circuits where wide common-mode range and EMI robustness are critical.
For engineers reviewing the TSB712AIYST datasheet, TSB712AIYST pinout, TSB712AIYST application, or TSB712AIYST equivalent, this device is selected for precision analog front-ends requiring stable DC accuracy across -40 °C to +125 °C, low noise (12 nV/√Hz), integrated EMI filtering, and 2 kV HBM ESD tolerance in MiniSO-8 packaging.
Technical Context
The TSB712AIYST employs complementary NPN/PNP input differential pairs enabling true rail-to-rail input operation from VCC− to (VCC+) + 0.1 V, with optimized performance over VCC− to (VCC+) − 1.5 V. Its architecture avoids phase reversal across the full absolute maximum common-mode range (VCC− − 0.2 V to VCC+ + 0.2 V).
It features an integrated EMI filter on inputs, achieving high immunity against RF rectification-induced offset shifts. The device maintains ≥105 dB CMRR and ≥100 dB PSRR over temperature, supporting precision closed-loop configurations in noisy motor control and sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz - supports stable unity-gain and moderate-gain filters up to ~100 kHz without compensation. |
| Slew Rate | 3 V/µs - enables accurate reproduction of fast 10–20 kHz signals with <1% distortion in 10 Vpp applications. |
| Input Offset Voltage | ≤300 µV max at 25 °C - ensures ≤0.003% error in 10 V full-scale current-sense amplifiers. |
| Supply Voltage Range | 2.7 V to 36 V single supply - interoperates with 3.3 V microcontrollers and 24 V industrial buses without level-shifting. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - preserves SNR >90 dB in 100 Hz–10 kHz instrumentation signal chains. |
| Common-Mode Range | VCC− to (VCC+) + 0.1 V - allows direct sensing of signals referenced to high-side bus voltages (e.g., 24 V rail monitoring). |
| EMI Rejection | Integrated input filter - suppresses RF-induced offset drift from GSM/ISM-band interference in automotive ECUs. |
| Temperature Range | −40 °C to +125 °C - qualified for under-hood and factory-floor environments without derating. |
Pinout & Package
TSB712AIYST is housed in a MiniSO-8 package (3.0 mm × 4.9 mm, 1.75 mm height), thermally optimized for industrial PCB layouts with RthJA = 190 °C/W. Its pinout supports dual independent op-amp channels with shared supplies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - drives loads up to 15 mA while maintaining rail-to-rail swing. |
| 2 | IN1− | Inverting input of Channel 1 - accepts differential signals with ±2 V max input voltage difference. |
| 3 | IN1+ | Non-inverting input of Channel 1 - enables high-Z sensor interfaces (e.g., strain gauges, Hall elements). |
| 4 | VCC− | Negative supply terminal - must be connected to system ground or negative rail; decoupling required within 5 mm. |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; supports dual-path signal conditioning. |
| 6 | IN2− | Inverting input of Channel 2 - supports differential configurations such as current-sense amplifiers with matched resistors. |
| 7 | OUT2 | Output of Channel 2 - independently buffered; no crosstalk (>125 dB at 1 kHz) between channels. |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V transient; requires 100 nF ceramic + 10 µF tantalum local decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in low-voltage (3.3 V) and high-voltage (24 V) systems without headroom loss. |
| Low 300 µV VOS max | Reduces calibration burden in factory-trimmed current sensors; eliminates need for external nulling circuitry. |
| Integrated EMI Filter | Prevents RF rectification artifacts in automotive CAN/LIN node analog stages without external RC networks. |
| 2 kV HBM ESD Rating | Survives handling and board-level ESD events per ISO 10605, reducing field failure risk in unshielded industrial enclosures. |
| −40 °C to +125 °C Operation | Guarantees parametric stability in engine control units and PLC analog I/O modules without thermal derating. |
| Dual Independent Channels | Allows simultaneous high-side current sense and voltage monitor in motor drives, minimizing component count and layout area. |

IC Role / Device Role / Timing Role: Low-noise, rail-to-rail buffer amplifying Hall sensor's ratiometric output (0.5–4.5 V) while rejecting EMI from nearby inverters. Use Value: Maintains 12-bit ENOB by limiting input-referred noise to 12 nV/√Hz and suppressing GSM 900 MHz interference via on-chip EMI filter. |
| Data Acquisition Front-End | Motor Phase Current Monitoring |
|
Use Scenario: Signal conditioning stage in portable multichannel DAQ for strain gauge and thermocouple measurements. IC Role / Device Role / Timing Role: Dual-channel instrumentation amplifier driver providing gain, filtering, and level-shifting before SAR ADC (e.g., ADS8860). Use Value: Enables 100 kSPS sampling with <0.001% nonlinearity thanks to 125 dB open-loop gain and 6 MHz bandwidth preserving settling time. |
Use Scenario: Real-time phase current feedback in 3-phase BLDC motor controller using three shunt resistors and synchronous sampling. IC Role / Device Role / Timing Role: Dual op-amp channel pair amplifying two phase currents simultaneously; third channel handled by second TSB712AIYST or shared resource.

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 |
|---|---|---|---|
| TSB712IYST | Higher max input offset voltage (±800 µV vs. ±300 µV); same GBW, noise, and package. | Acceptable in cost-sensitive industrial controls where calibration compensates for initial VOS. | Select when budget constraints outweigh need for factory-zero-calibration in automotive or medical-grade designs. |
| TSB512IYST | Same 36 V rating and rail-to-rail I/O, but lower GBP (6 MHz → 2.5 MHz) and higher VOS (±1.5 mV). | Suitable for low-bandwidth sensor buffering (e.g., RTD, thermistor) but not motor current loops. | Choose only if bandwidth demand is <100 kHz and supply current <1.2 mA is prioritized over precision. |
Compared with TSB712IYST, the TSB712AIYST provides tighter DC accuracy essential for uncalibrated current sensing, while TSB512IYST trades bandwidth and offset for lower quiescent current-making it viable only in non-critical, low-speed analog paths.

FAQ
What is the maximum capacitive load the TSB712AIYST can drive stably?
The TSB712AIYST is characterized for stable operation with up to 100 pF capacitive load at unity gain, per Figure 26 in DS12487. Driving >100 pF requires external series resistance (≥10 Ω) at the output or gain ≥10 to maintain ≥45° phase margin, as verified in phase margin vs. capacitive load testing at both 5 V and 36 V supplies.
Does the TSB712AIYST support dual-supply operation?
Yes - the TSB712AIYST operates from ±1.35 V to ±18 V dual supplies, confirmed in Table 4 (Operating Conditions) and Section 5.1. Its rail-to-rail input extends to VCC− − 0.2 V and VCC+ + 0.2 V, enabling true bipolar signal handling without clipping at supply extremes.
How does the integrated EMI filter function without external components?
The EMI filter is implemented as on-die RC networks at each input pin, tuned to attenuate RF energy above 100 MHz before it reaches the input differential pair. This is validated by EMIRR measurements showing >80 dB rejection at 900 MHz, eliminating need for external ferrite beads or RC snubbers in automotive ECU designs.
Is the TSB712AIYST pin-compatible with other ST dual op-amps in MiniSO-8?
No - the TSB712AIYST uses a unique pinout (OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, OUT2, VCC+) that differs from standard SO-8 dual op-amps like TS912 or LM358. Layout redesign is required; however, its footprint matches TSB712IYST and TSB712AYST exactly.
