Product details
Overview
TSB7192AIYST 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 and Hall effect sensor interfacing with minimal error across temperature.
For engineers reviewing the TSB7192AIYST datasheet, TSB7192AIYST pinout, TSB7192AIYST application, or TSB7192AIYST 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 - critical for motor control feedback loops and precision data acquisition under noisy conditions.
Technical Context
The TSB7192AIYST employs a complementary NPN/PNP input stage enabling true rail-to-rail common-mode input range from VCC− to (VCC+) + 0.1 V, with optimized performance between VCC− and (VCC+) − 1.5 V. Its open-loop gain exceeds 110 dB and CMRR reaches 115 dB at 25 °C, supporting high-precision closed-loop configurations.
Stability is ensured across capacitive loads up to 100 pF and output currents up to ±50 mA, with phase margin ≥63° at AV = +10. The device features low 12 nV/√Hz input voltage noise at 10 kHz and THD+N of 0.0022% at 1 kHz, making it suitable for wide-dynamic-range instrumentation amplifiers and active filter stages.
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 response in current-sense amplifiers. |
| Slew rate | 12 V/µs - ensures faithful reproduction of 1–2 MHz step signals without distortion in motor control feedback paths. |
| Input offset voltage | ±300 µV max at 25 °C - reduces baseline error in strain gauge bridges and shunt-based current measurement below 0.01% FS. |
| Supply voltage range | 2.7 V to 36 V - allows direct interface with 12 V/24 V automotive batteries and industrial 36 V rails without level-shifting. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive and factory-floor industrial environments. |
| Input voltage noise | 12 nV/√Hz at 10 kHz - preserves SNR in high-gain sensor front-ends such as load cell amplifiers. |
| EMI filtering | Integrated - suppresses RF-induced errors from switching power supplies and CAN bus transceivers without external RC networks. |
Pinout & Package
TSB7192AIYST is housed in a MiniSO-8 (SO8) surface-mount package with exposed pad for thermal enhancement and automotive-grade reliability. Pinout follows standard dual-opamp configuration with independent inputs and outputs per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - rail-to-rail swing enables full dynamic range utilization in single-supply data acquisition. |
| 2 | IN1− | Inverting input of Channel 1 - used for precision differential amplification and current-sense resistor monitoring. |
| 3 | IN1+ | Non-inverting input of Channel 1 - accepts signals from Hall sensors or resistive transducers with rail-to-rail common-mode support. |
| 4 | VCC− | Negative supply terminal - referenced to system ground in single-supply mode; required for dual-supply operation down to ±1.35 V. |
| 5 | IN2+ | Non-inverting input of Channel 2 - enables dual-channel signal conditioning (e.g., simultaneous voltage and current sensing). |
| 6 | IN2− | Inverting input of Channel 2 - supports matched gain configurations for differential-to-single-ended conversion. |
| 7 | OUT2 | Output of Channel 2 - independently buffered output avoids crosstalk in multi-sensor systems (125 dB isolation at 1 kHz). |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V absolute maximum, allowing robust operation during load-dump transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends to VCC+ + 0.1 V; output swings within 120 mV of rails at 2 mA load - eliminates need for level-shifting in 3.3 V/5 V microcontroller interfaces. |
| Stability at extreme gains | Guaranteed no oscillation at closed-loop gain ≥+10 or ≤−9 - simplifies design of high-gain transimpedance amplifiers without external compensation. |
| Low long-term drift | 0.57 µV/√month typical - ensures <1 µV total offset shift over 5-year field life, critical for uncalibrated industrial sensors. |
| Automotive qualification | AEC-Q100 Grade 1 compliant - validated for continuous operation at +125 °C ambient with 2 kV HBM ESD protection on all pins. |
| Capacitive load drive | Stable with ≥100 pF load - supports direct connection to ADC input filters and long PCB traces without phase-margin degradation. |
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 |
|---|---|---|---|
| TSB712A | Same 36 V supply, but 22 MHz GBP shared across dual channels; higher ICC (2.5 mA vs. 1.8 mA) | Lower power density - less suitable for thermally constrained PCBs in motor drivers | Prefer TSB7192AIYST when per-channel bandwidth and thermal headroom are critical |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. 2.8 µV/°C; lower GBP (350 kHz); no EMI filter | Better DC accuracy but insufficient bandwidth for >10 kHz feedback loops | Choose OPA2333AIDR only for ultra-low-drift DC-coupled sensor nodes, not dynamic control |
Compared with TSB712A and OPA2333AIDR, the TSB7192AIYST uniquely balances high-speed precision (22 MHz, 12 V/µs), rail-to-rail operation up to +125 °C, and integrated EMI immunity - making it optimal for automotive motor control and industrial real-time data acquisition where both bandwidth and ruggedness are mandatory.

FAQ
What is the maximum capacitive load the TSB7192AIYST can drive while maintaining stability?
The TSB7192AIYST is specified to remain stable with capacitive loads up to 100 pF at gain ≥+10, as verified by phase margin ≥63° in the datasheet. For loads exceeding 100 pF, external series resistance (typically 10–50 Ω) at the output is recommended to preserve stability, especially in high-current drive scenarios like driving ADC input filters or long cables.
Does the TSB7192AIYST support dual-supply operation, and what are the limits?
Yes, the TSB7192AIYST supports dual-supply operation from ±1.35 V to ±18 V, matching its single-supply range of 2.7 V to 36 V. The absolute maximum ratings allow ±20 V, but operation beyond ±18 V risks violating input common-mode or output swing specifications. Dual-supply use is common in precision test equipment where symmetric headroom improves dynamic range.
How does the integrated EMI filter function, and what frequencies does it suppress?
The integrated EMI filter attenuates high-frequency interference (typically 100 MHz–2.5 GHz) coupled onto input pins via PCB traces or nearby RF sources. It functions as a low-pass network internal to the input stage, reducing susceptibility without requiring external RC snubbers. This is validated by improved immunity to GSM/Bluetooth/Wi-Fi emissions in automotive EMC testing per ISO 11452-4.
Is the TSB7192AIYST pin-compatible with the TSB7191A or TSB7192 variants?
Yes - all TSB7191, TSB7191A, TSB7192, and TSB7192A share identical MiniSO-8 pinouts and footprint. The "A" suffix denotes enhanced input offset voltage (±300 µV max vs. ±800 µV) and improved CMRR at extended common-mode range. No layout change is needed when upgrading from TSB7192 to TSB7192AIYST, though electrical validation at temperature extremes is recommended.
