Product details
Overview
TSB7192AIYDT from STMicroelectronics is a precision rail-to-rail input/output operational amplifier in MiniSO-8 package, designed for high-accuracy signal conditioning in automotive and industrial systems. 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 high-side current sensing in 24 V motor control systems.
For engineers reviewing the TSB7192AIYDT datasheet, TSB7192AIYDT pinout, TSB7192AIYDT application, or TSB7192AIYDT equivalent, key selection criteria include guaranteed rail-to-rail operation up to +125 °C, integrated EMI filtering, stability at gain ≥ +10 or ≤ –9, and 2 kV HBM ESD tolerance for harsh environments.
Technical Context
The TSB7192AIYDT uses a complementary NPN/PNP input stage to achieve true rail-to-rail input common-mode 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.
Stability is ensured via internal compensation for gains ≥ +10 (non-inverting) or ≤ –9 (inverting), with phase margin ≥ 68° at 25 °C and capacitive load drive capability up to 100 pF. The device maintains low noise (12 nV/√Hz at 10 kHz) and THD+N of 0.0022% at 1 kHz, making it suitable for high-fidelity analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 22 MHz - supports stable closed-loop operation up to ~2 MHz at unity gain, enabling fast signal acquisition in data loggers. |
| Slew rate | 12 V/µs - ensures faithful reproduction of 1.9 MHz full-power sine waves at ±10 V output swing. |
| Input offset voltage | ±300 µV max at 25 °C - reduces DC error in precision current-sense amplifiers without trimming. |
| Supply voltage range | 2.7 V to 36 V - enables direct interface with 12 V/24 V automotive and industrial power rails. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive and factory-floor industrial use. |
| EMI filtering | Integrated - suppresses RF interference from switching power supplies and motor drives without external RC networks. |
| ESD tolerance | 2 kV HBM - enhances robustness during PCB handling and system integration in production environments. |
Pinout & Package
TSB7192AIYDT is housed in MiniSO-8 (SO8) package, a surface-mount, thermally enhanced 8-pin variant of SOIC with 0.65 mm pitch and exposed thermal pad (not electrically connected). This package supports higher power dissipation than SOT23-5 while maintaining compact footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output channel 1 - rail-to-rail capable, sourcing/sinking ≥20 mA over full temperature range. |
| 2 | IN1– | Inverting input channel 1 - differential pair node with ±10 mA absolute max input current rating. |
| 3 | IN1+ | Non-inverting input channel 1 - complementary input stage node; bias current polarity shifts near VCC+. |
| 4 | VCC– | Negative supply terminal - referenced to system ground in single-supply operation; must be decoupled. |
| 5 | IN2+ | Non-inverting input channel 2 - identical electrical characteristics to IN1+, supports dual-channel instrumentation. |
| 6 | IN2– | Inverting input channel 2 - matched to IN1–; enables independent differential gain stages per channel. |
| 7 | OUT2 | Output channel 2 - fully independent output with same drive strength and rail-to-rail swing as OUT1. |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V absolute max; requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Common-mode range extends to VCC+ + 0.1 V and output swings within 120 mV of rails at 2 mA load - enables full dynamic range utilization in low-voltage systems. |
| Low input offset drift | 2.8 µV/°C max over –40 °C to +125 °C - minimizes temperature-induced error in strain gauge bridges and precision transducer interfaces. |
| Stable at extreme gains | Guaranteed stability at non-inverting gain ≥ +10 and inverting gain ≤ –9 - eliminates need for external compensation in most feedback configurations. |
| High PSRR and CMRR | 125 dB PSRR and 130 dB CMRR at 25 °C - rejects supply ripple and common-mode noise in noisy industrial environments. |
| Automotive-grade qualification | AEC-Q100 Grade 1 compliant - validated for reliability in automotive powertrain and body electronics applications. |

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 |
|---|---|---|---|
| TSB7192IYDT | Standard grade (±800 µV max Vio at 25 °C vs. ±300 µV for TSB7192A); same package, pinout, and bandwidth. | Lacks A-grade offset spec - suitable for cost-sensitive industrial controls where <1 mV DC error is acceptable. | Select when budget constraints outweigh need for sub-millivolt precision at temperature extremes. |
| TSB712AIYDT | Dual-channel, 22 MHz GBP, but lower CMRR (120 dB typ) and no integrated EMI filter; same supply range and temp grade. | Higher channel density per package - ideal for space-constrained multi-sensor systems requiring matched dual amplifiers. | Choose for dual-channel applications where EMI immunity is managed externally and layout allows tighter coupling. |
Compared with TSB7192IYDT, the TSB7192AIYDT provides tighter initial offset and lower drift for critical DC-coupled measurements; versus TSB712AIYDT, it trades dual-channel integration for superior EMI rejection and CMRR in single-channel high-noise environments.

FAQ
What is the maximum capacitive load the TSB7192AIYDT can drive while maintaining stability?
The TSB7192AIYDT is stable driving up to 100 pF capacitive load in unity-gain configuration, as verified by phase margin ≥68° at 25 °C. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is required to preserve stability, especially in high-current drive scenarios.
Does the TSB7192AIYDT support single-supply operation with input signals extending to the negative rail?
Yes - its rail-to-rail input stage operates from VCC– to VCC+ + 0.1 V, allowing inputs to reach the negative supply rail (typically ground in single-supply setups) without phase reversal or clipping. Performance is optimized across VCC– to VCC+ – 1.5 V, with minor CMRR degradation near VCC+.
How does the integrated EMI filter function, and what frequencies does it suppress?
The integrated EMI filter attenuates RF interference in the 100 MHz to 2 GHz range, primarily targeting emissions from switch-mode power supplies and digital clock harmonics. It functions as a built-in RC low-pass network on each input, eliminating need for discrete 100 Ω + 100 pF external filters commonly used with standard op-amps.
Is the TSB7192AIYDT pin-compatible with other devices in the TSB719x family?
Yes - TSB7192AIYDT shares identical MiniSO-8 pinout and footprint with TSB7192IYDT, TSB7191AIYDT, and TSB7191IYDT. All variants maintain compatible electrical behavior, though offset voltage, drift, and CMRR differ between 'A' (precision) and standard grades.
