Product details
Overview
TSX7192IYDT from STMicroelectronics is a dual, decompensated, rail-to-rail input/output operational amplifier optimized for precision, low-power, and high-voltage operation. It delivers 200 µV max input offset voltage, 9 MHz gain bandwidth product, 2.7–16 V supply range, and operates across –40 °C to +125 °C - enabling use in automotive current sensing and battery-powered instrumentation.
For engineers reviewing the TSX7192IYDT datasheet, TSX7192IYDT pinout, TSX7192IYDT application, or TSX7192IYDT equivalent, key selection criteria include its minimum gain ≥10 stability requirement, 50 pA max input bias current for high-impedance sensor interfacing, rail-to-rail output swing within 40 mV of rails at 10 kΩ load, and 4 kV HBM ESD rating for harsh environments.
Technical Context
The TSX7192IYDT is a decompensated op amp requiring closed-loop gain ≥10 for stability, confirmed by phase margin ≥42° at G = 10 with 100 pF capacitive load. Its rail-to-rail input stage extends common-mode range to (VCC– – 0.1 V) to (VCC+ + 0.1 V), while rail-to-rail output achieves ≤40 mV saturation voltage at 10 kΩ load to mid-supply.
It features MOSFET input architecture delivering 1 TΩ input resistance and 50 pA max input bias current at 25 °C, enabling accurate signal conditioning for high-impedance sources. Input offset voltage drift is specified at 2.5 µV/°C max, and long-term drift reaches 500 µV after 1000 h at 125 °C (extrapolated).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 200 µV max at 25 °C - enables <1 LSB error in 12-bit systems with 2.048 V reference |
| Gain bandwidth product | 9 MHz - supports stable closed-loop operation up to 10× gain with >1 MHz small-signal bandwidth |
| Supply voltage range | 2.7 V to 16 V - allows single-supply operation from Li-ion (3.0–4.2 V) to industrial 12 V rails |
| Input bias current | 50 pA max - ensures <5 mV error across 100 MΩ source impedance at 25 °C |
| Rail-to-rail output swing | ≤40 mV from rails at 10 kΩ load - preserves dynamic range in low-voltage 3.3 V or 5 V systems |
| ESD tolerance | 4 kV HBM - meets automotive IEC 61000-4-2 Level 3 for board-level robustness |
| Operating temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
Pinout & Package
TSX7192IYDT is housed in an SO8 (Small Outline 8-pin) package with standard dual op amp pinout and surface-mount footprint. Pin 1 is marked with a dot or bevelled corner; device orientation follows JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Inverting input (A) | Op amp A negative input | Accepts differential signal; rail-to-rail common-mode range supports full-supply input tracking |
| Non-inverting input (A) | Op amp A positive input | High-impedance node (1 TΩ); 50 pA max bias current minimizes error in sensor bridges |
| Output (A) | Op amp A output | Rail-to-rail swing to within 40 mV of VCC or GND at 10 kΩ load; drives 37 mA sink/source |
| VCC– | Negative supply (GND) | Reference for dual-supply operation or ground return in single-supply configurations |
| VCC+ | Positive supply | Accepts 2.7–16 V; internal protection diodes clamp input overvoltage to ±0.5 V beyond rails |
| Inverting input (B) | Op amp B negative input | Independent channel; identical specs to Channel A - enables dual-path signal conditioning |
| Non-inverting input (B) | Op amp B positive input | Same high-Z, low-bias performance as Channel A - suitable for matched differential front-ends |
| Output (B) | Op amp B output | Independent rail-to-rail output; no crosstalk specified - supports isolated feedback paths |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset voltage | 200 µV max ensures <0.01% gain error in precision instrumentation amplifiers |
| Rail-to-rail I/O | Full input range (VCC– – 0.1 V to VCC+ + 0.1 V) and output swing to within 40 mV of rails maximize usable signal headroom |
| Stable at G ≥ 10 | Decompensated design reduces quiescent current vs. unity-gain-stable equivalents - saves 150 µA per channel at 4 V |
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for 125 °C ambient operation and 150 °C junction temperature |
| High ESD immunity | 4 kV HBM rating eliminates need for external TVS on inputs in most automotive PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSX712IDT | Lower GBP (1.5 MHz), same 200 µV VOS, unity-gain stable, 350 µA ICC | Targeted at DC/low-frequency (<100 kHz) precision apps where speed is secondary to power savings | Select when gain ≥10 stability constraint is unacceptable and bandwidth <200 kHz suffices |
| TSX922IYDT | Higher GBP (10 MHz), 1.5 mV VOS, rail-to-rail output only, 1.2 mA ICC | Optimized for high-speed active filtering and fast-settling ADC drivers where offset is relaxed | Select when >5 MHz bandwidth is required and 1.5 mV offset is acceptable in system budget |
Compared with TSX7192IYDT, TSX712IDT trades bandwidth for lower power and unconditional stability, while TSX922IYDT sacrifices precision for speed and higher supply current - making TSX7192IYDT optimal for automotive current sensing where 9 MHz bandwidth, 200 µV offset, and 125 °C operation intersect.

FAQ
Can TSX7192IYDT be used at unity gain?
No. TSX7192IYDT is decompensated and requires minimum closed-loop gain of 10 for stability, as verified by phase margin ≥42° at G = 10 with 100 pF load. Attempting unity-gain configuration causes oscillation, confirmed in Figure 21–22 Bode plots showing peaking and reduced phase margin below G = 10.
What is the maximum capacitive load the TSX7192IYDT can drive without compensation?
TSX7192IYDT remains stable with up to 100 pF capacitive load at G = 10, per phase margin testing in Table 3. Driving >100 pF requires external compensation (e.g., series resistor at output), as overshoot exceeds 10% beyond that point, shown in Figure 24.
Does TSX7192IYDT support true split-supply operation?
Yes. TSX7192IYDT operates with VCC+ and VCC– pins accepting symmetric (±2.7 V to ±8 V) or asymmetric supplies (e.g., +12 V / –5 V), provided total differential voltage stays ≤18 V and common-mode input range remains within (VCC– – 0.1 V) to (VCC+ + 0.1 V), per Table 2.
How does input offset voltage drift affect accuracy over temperature?
Input offset voltage drift is 2.5 µV/°C max, causing ≤450 µV total offset from –40 °C to +125 °C (ΔT = 165 °C). This adds ≤0.022% error in a 2 V full-scale system, validated by Figure 5 and Table 3 data across temperature sweeps.
