Product details
Overview
TSB7192IDT 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 - enabling high-side current sensing and Hall effect sensor interfacing with minimal error across temperature.
For engineers reviewing the TSB7192IDT datasheet, TSB7192IDT pinout, TSB7192IDT application, or TSB7192IDT equivalent, key selection criteria include its guaranteed rail-to-rail input common-mode range (VCC− to VCC+ + 0.1 V), stability at gain ≥ +10/−9, integrated EMI filtering, and −40 °C to +125 °C automotive-grade operation.
Technical Context
The TSB7192IDT employs a complementary NPN/PNP input stage to achieve true rail-to-rail input operation, with optimized performance over VCC− to (VCC+ − 1.5 V) and a known transition region near VCC+ − 1 V that affects CMRR and input offset voltage. Its open-loop gain exceeds 110 dB and CMRR reaches 130 dB under specified conditions, supporting precision closed-loop configurations.
Stability is ensured for gains ≥ +10 (non-inverting) or ≤ −9 (inverting) without external compensation, with 68° phase margin at AV = +10 and 10 kΩ/100 pF load. The device drives up to 100 pF capacitive loads while maintaining >63° phase margin and features low 12 nV/√Hz input voltage noise at 10 kHz.
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, suitable for fast data acquisition front-ends. |
| Slew rate | 12 V/µs - enables accurate reproduction of 1.9 MHz full-power sine waves at ±10 V output swing. |
| Input offset voltage | ±300 µV max at 25 °C - limits DC error to <0.003% of 10 V full-scale, critical for strain gauge and current-sense amplification. |
| Supply voltage range | 2.7 V to 36 V single supply - eliminates need for dual supplies in motor control and industrial power monitoring. |
| Input voltage noise | 12 nV/√Hz at 10 kHz - ensures <1.2 µV RMS noise in 1 MHz bandwidth, preserving SNR in precision instrumentation. |
| Common-mode input range | VCC− to VCC+ + 0.1 V - allows direct sensing of signals at either supply rail, essential for high-side current measurement. |
| EMI filter integration | On-chip RF rejection - suppresses 100 MHz–1 GHz interference without external ferrites, improving robustness in noisy motor drives. |
| ESD tolerance | 2 kV HBM - meets IEC 61000-4-2 Level 2 requirements for industrial board-level reliability. |
Pinout & Package
TSB7192IDT is housed in a MiniSO-8 (SO8) surface-mount package with exposed thermal pad, rated for 190 °C/W junction-to-ambient thermal resistance. This compact 3.0 mm × 4.9 mm footprint supports high-density PCB layouts while enabling efficient heat dissipation in thermally constrained applications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of channel 1; rail-to-rail swing supports direct interface to SAR ADCs or comparator inputs. |
| 2 | IN1− | Inverting input of channel 1; matched impedance path required for optimal CMRR and noise rejection. |
| 3 | IN1+ | Non-inverting input of channel 1; accepts signals from VCC− to VCC+ + 0.1 V without phase reversal. |
| 4 | VCC− | Negative supply terminal; must be decoupled locally with 100 nF ceramic capacitor to minimize PSRR degradation. |
| 5 | IN2+ | Non-inverting input of channel 2; electrically isolated from IN1+ but shares same ESD protection architecture. |
| 6 | IN2− | Inverting input of channel 2; differential pair biasing identical to IN1−, ensuring matched AC performance between channels. |
| 7 | OUT2 | Amplified output of channel 2; independent output stage allows dual-path signal conditioning without crosstalk (>125 dB at 1 kHz). |
| 8 | VCC+ | Positive supply terminal; internal bandgap reference and EMI filter connect here; requires low-ESR bulk + ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization across 2.7–36 V supply, eliminating level-shifting circuits in battery-powered and 24 V industrial systems. |
| Low input offset drift | 2.8 µV/°C max - reduces temperature-induced gain error to <0.3 mV over −40 °C to +125 °C, critical for uncalibrated embedded sensors. |
| Stable at gain +10/−9 | Eliminates need for external compensation networks in standard transimpedance or difference amplifier configurations. |
| Integrated EMI filter | Rejects high-frequency noise from switching regulators and motor drivers without adding BOM cost or board area. |
| Automotive-grade qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - validated for engine control units, battery management, and ADAS sensor interfaces. |
| High output drive capability | ±20 mA min output current - directly drives 500 Ω loads or multiple logic inputs without buffer stages. |

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 TSB7192IDT) at 25 °C; same package and pinout. | Better suited for DC-critical applications like precision weight scales where initial offset dominates total error budget. | Select TSB7192AIDT when <0.003% initial gain error is mandatory; otherwise TSB7192IDT offers cost advantage with identical AC specs. |
| TSB712AIDT | Dual-channel, 22 MHz GBP, but only 6 MHz typical GBP per channel in dual configuration; same 36 V supply and rail-to-rail I/O. | Optimized for space-constrained dual-path designs (e.g., differential sensor pairs), not single-channel high-speed use cases. | Choose TSB712AIDT when two matched amplifiers are needed on one die; avoid for single-channel 22 MHz bandwidth requirements. |
Compared with TSB7192AIDT, the TSB7192IDT trades tighter initial offset for lower unit cost while retaining identical speed, noise, and thermal performance; versus TSB712AIDT, it provides superior single-channel bandwidth and output drive but lacks channel matching for differential signal chains.

FAQ
What is the maximum capacitive load the TSB7192IDT can drive while remaining stable?
The TSB7192IDT maintains ≥63° phase margin driving up to 100 pF capacitive load with 10 kΩ series resistance, as verified in Figure 25 of DS12641. For loads exceeding 100 pF, external isolation resistance or gain adjustment is required to prevent peaking or oscillation - no internal compensation is provided beyond this limit.
Does the TSB7192IDT exhibit phase reversal when input voltage exceeds the supply rails?
No. The TSB7192IDT guarantees no phase reversal for any input common-mode voltage within the absolute maximum rating window of (VCC− − 200 mV) to (VCC+ + 200 mV), as confirmed in Section 5.2 of the datasheet. This behavior is enabled by its dual complementary input stage architecture.
How does the integrated EMI filter affect RF immunity performance?
The on-chip EMI filter attenuates high-frequency interference above 100 MHz by >30 dB, significantly reducing susceptibility to radiated emissions from switch-mode power supplies and motor inverters. This eliminates the need for external RC filters in most industrial environments, preserving signal integrity without added latency or component count.
Can the TSB7192IDT operate from a 3.3 V supply while maintaining rail-to-rail output swing?
Yes. At VCC = 3.3 V, the TSB7192IDT achieves rail-to-rail output swing with <120 mV saturation voltage at 2 mA load (per Table 5), delivering >3.0 V peak-to-peak output into high-impedance loads. Input common-mode range extends from 0 V to 3.4 V, supporting direct interface to 3.3 V logic and sensors.
