Product details
Overview
TSB7192IYDT from STMicroelectronics is a precision rail-to-rail input/output operational amplifier in MiniSO-8 package, designed for high-accuracy signal conditioning in wide-supply industrial and automotive 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 (±1.35 V to ±18 V dual). It is used in high-side current sensing circuits where rail-to-rail output swing and low noise (12 nV/√Hz) are critical for ADC interface fidelity.
For engineers reviewing the TSB7192IYDT datasheet, TSB7192IYDT pinout, TSB7192IYDT application, or TSB7192IYDT equivalent, key selection criteria include guaranteed stability at gain ≥ +10/−9, integrated EMI filtering for noisy environments, −40 °C to +125 °C extended temperature operation, and 2 kV HBM ESD tolerance for robust board-level reliability.
Technical Context
The TSB7192IYDT employs a complementary NPN/PNP rail-to-rail input stage enabling full common-mode range from VCC− to (VCC+)+0.1 V, with optimized performance over VCC− to (VCC+)−1.5 V. Its internal architecture includes integrated EMI filtering on inputs and is qualified for automotive-grade applications per AEC-Q100.
It achieves stable unity-gain-compensated operation only above gain +10 (non-inverting) or −9 (inverting), confirmed by 68° phase margin at AV = +10 and 100 pF capacitive load. The device maintains 110 dB open-loop gain and 115 dB CMRR at 25 °C within its specified common-mode window.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 22 MHz - supports closed-loop bandwidth up to ~2 MHz at gain = 10, suitable for fast current-sense loop compensation. |
| Slew Rate | 12 V/µs - enables accurate reproduction of 1–2 MHz small-signal steps without distortion in motor control feedback paths. |
| Input Offset Voltage | ±300 µV max at 25 °C - ensures ≤0.008% error in 36 V full-scale current-shunt measurements before calibration. |
| Supply Voltage Range | 2.7 V to 36 V single supply - interoperable with 3.3 V microcontrollers and 24 V industrial buses without level shifting. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - contributes <0.5 µVPP integrated noise in 10 Hz–100 kHz band, critical for strain gauge amplification. |
| Common-Mode Rejection | 115 dB at 25 °C - rejects >10⁵:1 of power-supply ripple and ground-bounce coupling in high-side sensing configurations. |
| ESD Tolerance | 2 kV HBM - meets IEC 61000-4-2 Level 3 system-level ESD immunity requirements without external protection. |
Pinout & Package
TSB7192IYDT 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 (not electrically connected). It is footprint-compatible with standard SO8 but offers improved thermal resistance (RthJA = 190 °C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of channel 1; rail-to-rail swing supports direct interface to SAR ADC reference buffers. |
| 2 | IN1− | Inverting input of channel 1; accepts differential signals up to ±2 V differential without damage when series-limited to 10 mA. |
| 3 | IN1+ | Non-inverting input of channel 1; rail-to-rail common-mode range enables direct connection to shunt resistor midpoints. |
| 4 | VCC− | Negative supply terminal; must be tied to system ground or negative rail; decoupling capacitor required within 5 mm. |
| 5 | IN2+ | Non-inverting input of channel 2; independent of channel 1, enabling dual-path sensor conditioning (e.g., current + voltage sense). |
| 6 | IN2− | Inverting input of channel 2; supports matched dual instrumentation amplifier topologies with shared gain-setting resistors. |
| 7 | OUT2 | Amplified output of channel 2; identical AC/DC specs to OUT1; allows simultaneous monitoring of two transducer outputs. |
| 8 | VCC+ | Positive supply terminal; accepts up to +40 V absolute maximum; requires local 100 nF ceramic + 10 µF tantalum decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization across 2.7–36 V supplies, eliminating headroom loss in low-voltage data acquisition front-ends. |
| Integrated EMI filter | Reduces susceptibility to 100 MHz–1 GHz RF interference without external RC networks-critical for automotive EMC compliance. |
| Stable at gain +10/−9 | Guarantees oscillation-free operation in high-gain current-sense amplifiers and active filters without external compensation. |
| 2 kV HBM ESD tolerance | Eliminates need for discrete TVS diodes at op-amp inputs in factory-handled industrial modules and EV battery management systems. |
| −40 °C to +125 °C operation | Qualified for under-hood automotive and industrial PLC environments where ambient temperature exceeds 85 °C. |

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 |
|---|---|---|---|
| TSB7192AIDT | Enhanced input offset voltage (±300 µV max vs. ±800 µV for TSB7192); same MiniSO-8 package and pinout. | Better suited for high-accuracy DC-coupled measurement chains where initial offset dominates total error budget. | Select TSB7192AIDT when system-level calibration is impractical and <0.01% gain error is required at room temperature. |
| TSB712AIDT | Dual-channel, 22 MHz GBP, but lower CMRR (95 dB typ.) and no integrated EMI filter; same supply range and temperature grade. | Appropriate for cost-sensitive dual-sensor systems where EMI immunity is managed at PCB layout level. | Choose TSB712AIDT only if second amplifier channel is needed and board-level shielding replaces EMI filter function. |
Compared with TSB7192IYDT, TSB7192AIDT improves DC accuracy without trade-offs in speed or ruggedness, while TSB712AIDT trades EMI hardening and CMRR for dual-channel integration-making TSB7192IYDT optimal for single-channel, noise-critical industrial sensing.

FAQ
Is TSB7192IYDT pin-compatible with TSB7191IYDT?
Yes, both are MiniSO-8 packaged dual op-amps with identical pinout (OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, OUT2, VCC+). However, TSB7192IYDT specifies tighter input offset voltage (±300 µV max vs. ±800 µV) and higher CMRR (115 dB vs. 105 dB), making it preferable for precision applications where initial accuracy is critical.
Can TSB7192IYDT drive 100 pF capacitive loads stably?
Yes, the datasheet guarantees stability with ≥100 pF capacitive loads at gain ≥+10, verified by 68° phase margin at 25 °C. For gains below +10 or higher capacitance, external isolation resistance (≥100 Ω) in series with the output is required to maintain phase margin above 45°.
What is the maximum differential input voltage before damage occurs?
The absolute maximum differential input voltage is ±2 V. Exceeding this risks forward-biasing internal ESD diodes and causing >10 mA current flow, which may damage the input stage. If differential voltage exceeds ±2 V-such as during output saturation-series input resistors must limit current to ≤10 mA.
Does TSB7192IYDT support dual-supply operation?
Yes, it operates from ±1.35 V to ±18 V dual supplies, maintaining rail-to-rail input/output swing and all specified AC/DC parameters. Common-mode input range extends from VCC− to (VCC+)+0.1 V, allowing inputs to reach beyond either rail by 100 mV without phase reversal or latch-up.
