Product details
Overview
TSB7192IST from STMicroelectronics is a precision rail-to-rail input/output operational amplifier in MiniSO-8 package, designed for high-accuracy signal conditioning in 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 - enabling use in high-side current sensing and Hall effect sensor interfaces.
For engineers reviewing the TSB7192IST datasheet, TSB7192IST pinout, TSB7192IST application, or TSB7192IST equivalent, key selection criteria include its guaranteed rail-to-rail operation up to +125 °C, integrated EMI filter, 2 kV HBM ESD tolerance, and stability at gain ≥ +10 or ≤ –9 - critical for motor control feedback loops and strain gauge amplification.
Technical Context
The TSB7192IST employs a complementary NPN/PNP rail-to-rail input stage, supporting common-mode input range from 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.
It features internal ESD diodes on inputs tied to both rails, requiring external series resistors if input voltages exceed supply rails by >0.2 V or differential input exceeds ±2 V. Phase margin remains ≥63° at gain +10 with 100 pF capacitive load, ensuring robust stability in closed-loop configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 22 MHz - enables stable closed-loop operation up to ~2 MHz at unity gain, suitable for fast data acquisition front-ends. |
| Slew Rate | 12 V/µs - supports full-scale 10 V output transitions in <0.84 µs, critical for pulse-width modulated motor control signals. |
| Input Offset Voltage | ±300 µV max at 25 °C - ensures sub-0.01% error in 3.3 V reference-based current sense amplifiers. |
| Supply Voltage Range | 2.7 V to 36 V - accommodates wide-input industrial power rails and battery-backed instrumentation without level-shifting. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - maintains SNR >90 dB in 100 kHz bandwidth applications like strain gauge bridges. |
| EMI Filter Integration | On-chip RF rejection - suppresses GSM/ISM-band interference without external RC filters, reducing PCB area and BOM count. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and factory-floor industrial environments. |
Pinout & Package
TSB7192IST 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). Pinout follows standard dual op-amp configuration with independent input and output terminals per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output Channel 1 | Low-impedance buffered output capable of sourcing/sinking 20 mA at –40 °C to +125 °C, rail-to-rail swing. |
| 2 (IN1–) | Inverting Input Channel 1 | Differential node for negative feedback; accepts common-mode voltage up to VCC+ + 0.1 V. |
| 3 (IN1+) | Non-inverting Input Channel 1 | High-impedance node (IIB < 300 nA) with rail-to-rail common-mode range and no phase reversal. |
| 4 (VCC–) | Negative Supply Voltage | Reference return for dual-supply operation; also serves as ground reference in single-supply configurations. |
| 5 (IN2+) | Non-inverting Input Channel 2 | Independent high-Z input for second channel; shares same ESD protection and rail-to-rail behavior as IN1+. |
| 6 (IN2–) | Inverting Input Channel 2 | Second differential input; supports matched gain-setting networks for dual-channel instrumentation. |
| 7 (OUT2) | Output Channel 2 | Fully independent output with identical drive strength and noise performance as OUT1. |
| 8 (VCC+) | Positive Supply Voltage | Primary power rail; supports up to +40 V absolute maximum, enabling overvoltage-tolerant system design. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage (2.7 V) and high-voltage (36 V) systems without clipping. |
| Stable at gain ≥ +10 or ≤ –9 | Eliminates need for external compensation in most transimpedance and differential amplifier configurations. |
| Integrated EMI filter | Reduces susceptibility to 400–2500 MHz RF interference without adding external components or layout complexity. |
| 2 kV HBM ESD tolerance | Meets IEC 61000-4-2 Level 3 requirements, simplifying system-level ESD protection design. |
| Extended temperature range | Guaranteed parametric performance from –40 °C to +125 °C supports AEC-Q100 Grade 1 compliance pathways. |

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), lower drift (2.8 µV/°C), and improved CMRR at rail-to-rail common-mode range. | Better suited for high-accuracy DC-coupled applications like precision weigh scales and medical sensors where long-term drift matters. | Select TSB7192AIST when offset and drift specs dominate over cost; otherwise TSB7192IST offers proven performance at lower price point. |
| TSB712AIST | Same 22 MHz GBP but dual-channel only; higher supply current (2.3 mA/ch vs. 1.8 mA/ch), no integrated EMI filter, and no guaranteed stability at gain –9. | Optimized for space-constrained dual-signal paths (e.g., differential sensor pairs), not single-channel high-drive or EMI-sensitive layouts. | Choose TSB712AIST only when dual-channel integration reduces board area more than EMI filter value; avoid for single-channel high-reliability designs. |
Compared with TSB7192AIST, the TSB7192IST trades tighter DC specs for broader availability and lower unit cost, while retaining identical AC performance, thermal rating, and EMI resilience - making it optimal for cost-sensitive industrial motor drives and test equipment where ±800 µV offset is acceptable.

FAQ
What is the minimum stable gain configuration for TSB7192IST?
The TSB7192IST is unconditionally stable at non-inverting gains ≥ +10 and inverting gains ≤ –9 across –40 °C to +125 °C, with 100 pF capacitive load. This eliminates need for external compensation in most current-sense and sensor-amplifier circuits, unlike many general-purpose op-amps requiring gain ≥ +25 for stability.
Does TSB7192IST support true rail-to-rail input at the positive rail?
Yes - the input common-mode range extends to (VCC+) + 0.1 V, and the device exhibits no phase reversal within the absolute maximum ratings window (VCC– – 0.2 V to VCC+ + 0.2 V). However, optimal CMRR and offset performance occur below VCC+ – 1.5 V due to PNP/NPN input pair transition.
Can TSB7192IST drive heavy capacitive loads directly?
It is characterized for stable operation with up to 100 pF capacitive load at gain +10. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is required to maintain phase margin >60°, as confirmed in Figures 24 and 25 of DS12641 Rev 5.
Is TSB7192IST pin-compatible with other ST dual op-amps in MiniSO-8?
No - TSB7192IST uses standard dual-op-amp pinout (OUT1, IN1–, IN1+, VCC–, IN2+, IN2–, OUT2, VCC+), but TSB712AIST and TSB572 follow different pin assignments. Always verify pin mapping against respective datasheets; direct substitution without layout review risks functional failure.
