Product details
Overview
TSB7192IYST from STMicroelectronics is a precision rail-to-rail input/output operational amplifier in MiniSO-8 package, designed for high-accuracy current sensing and instrumentation. It delivers 22 MHz gain bandwidth, 12 V/µs slew rate, 300 µV max input offset voltage at 25 °C, and operates from 2.7 V to 36 V single supply - enabling use in automotive motor control and industrial process monitoring.
For engineers reviewing the TSB7192IYST datasheet, TSB7192IYST pinout, TSB7192IYST application, or TSB7192IYST equivalent, key selection criteria include its guaranteed rail-to-rail operation up to +125 °C, integrated EMI filter, 2 kV HBM ESD rating, and stability at gain ≥ +10 or ≤ –9 - critical for high-side current sensing and Hall-effect sensor signal conditioning.
Technical Context
The TSB7192IYST employs a complementary NPN/PNP input stage enabling true rail-to-rail common-mode input range (VCC– to VCC+ + 0.1 V), with optimized performance across VCC– to VCC+ – 1.5 V. Its open-loop gain exceeds 110 dB and CMRR reaches 130 dB under specified conditions, supporting precision closed-loop configurations.
It features internal ESD protection diodes on inputs, requiring external series resistors if input voltages exceed rails by >0.2 V to limit current to ≤10 mA. Phase margin remains ≥63° at gain +10 with 100 pF capacitive load, ensuring robust stability in demanding feedback networks.
Key Specifications

Pinout & Package
TSB7192IYST is housed in MiniSO-8 (SO8) package - a surface-mount, thermally enhanced 8-pin variant of SOIC with 1.27 mm pitch and exposed thermal pad for improved power dissipation in continuous-current applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of channel 1; rail-to-rail swing supports full dynamic range utilization in single-supply designs. |
| 2 | IN1– | Inverting input of channel 1; differential pair node with ±2 V absolute max input voltage differential. |
| 3 | IN1+ | Non-inverting input of channel 1; complementary PNP/NPN input stage enables operation down to VCC–. |
| 4 | VCC– | Negative supply terminal; must be connected to ground or negative rail; serves as reference for input common-mode and output swing. |
| 5 | IN2+ | Non-inverting input of channel 2; electrically isolated but thermally coupled to channel 1 for matched drift behavior. |
| 6 | IN2– | Inverting input of channel 2; shares same ESD protection architecture and bias current characteristics as IN1–. |
| 7 | OUT2 | Amplified output of channel 2; independent output stage supports dual-path signal conditioning without crosstalk degradation. |
| 8 | VCC+ | Positive supply terminal; accepts up to +40 V absolute max; powers both channels and internal bias circuitry. |

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 |
|---|---|---|---|
| TSB7192AIST | Enhanced input offset voltage (±300 µV max vs. ±800 µV for TSB7192); identical pinout and specs otherwise. | Required where <0.1% measurement accuracy is mandated across –40 °C to +125 °C (e.g., automotive BMS). | Select TSB7192AIST when offset drift and long-term stability are prioritized over cost-sensitive industrial use. |
| TSB712AIST | Dual-channel, 22 MHz GBP, but lower CMRR (120 dB max) and no integrated EMI filter; same MiniSO-8 footprint. | Suitable for non-critical dual-path amplification (e.g., dual-axis position feedback), not high-EMI motor control. | Choose TSB712AIST only when dual-channel count justifies trade-off in EMI immunity and CMRR for cost reduction. |
Compared with TSB7192IYST, TSB7192AIST offers tighter offset specification for high-accuracy current sensing, while TSB712AIST provides dual-channel integration at reduced EMI robustness - making TSB7192IYST the optimal balance of precision, noise, and automotive-grade resilience in single-channel applications.

FAQ
What is the maximum capacitive load the TSB7192IYST can drive while maintaining stability?
The TSB7192IYST is stable with up to 100 pF capacitive load at gain +10, as verified by phase margin ≥63° per DS12641 Rev 5. Driving >100 pF requires external isolation resistor (e.g., 10–50 Ω in series with output) to preserve stability in motor control feedback paths.
Does the TSB7192IYST support true rail-to-rail input at the positive rail?
Yes - the input common-mode range extends to VCC+ + 0.1 V, enabled by complementary NPN/PNP input pairs. However, optimal CMRR and offset performance occur below VCC+ – 1.5 V; operation near VCC+ may degrade CMRR by up to 35 dB per datasheet Figure 10–11.
Can the TSB7192IYST be used as a comparator?
No - it is not designed for open-loop comparator operation. Input differential voltage must be limited to ±2 V to avoid excessive current through internal ESD diodes. Sustained saturation causes phase reversal risk and potential damage without external current limiting.
How does the integrated EMI filter function without external components?
The EMI filter is implemented as on-die RC low-pass network at each input pin, attenuating RF interference above ~100 MHz. It requires no external parts and maintains full DC precision - validated per ISO 11452-4 radiated immunity testing at 10–2000 MHz with 200 V/m field strength.
