Product details
Overview
TSV794IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-precision, high-bandwidth signal conditioning. It delivers 50 MHz gain bandwidth, 30 V/µs slew rate, 200 µV max input offset voltage, 1 pA typ. input bias current, and operates from 2.2 V to 5.5 V across –40 °C to +125 °C - enabling accurate low-side/high-side current sensing in automotive power management systems.
For engineers reviewing the TSV794IYPT datasheet, TSV794IYPT pinout, TSV794IYPT application, or TSV794IYPT equivalent, this device is selected for photodiode transimpedance amplification, ADC input buffering, and solar-powered system power management where low noise (6.5 nV/√Hz @ 10 kHz), rail-to-rail operation, and AEC-Q100-compliant stability are critical.
Technical Context
The TSV794 employs dual-input-stage architecture with seamless transition between NMOS and PMOS input pairs, supporting rail-to-rail common-mode input range (VCC– – 0.1 V to VCC+ + 0.1 V) and maintaining >90 dB CMRR over full temperature range. Its unity-gain-stable design achieves 53° phase margin into 10 kΩ || 22 pF loads.
It features internal compensation optimized for capacitive loads up to 1 nF, supports stable operation with 22 pF specified load, and exhibits <15 µVpp 0.1–10 Hz input noise - making it suitable for precision DC-coupled amplification in noisy automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth, low-offset op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSZ182IDT | Zero-drift architecture (3 MHz GBP, 1.8 V/µs SR), 12 µV max Vio, higher DC precision but lower bandwidth. | Better for µV-level DC measurements (e.g., strain gauges); unsuitable for >100 kHz signal conditioning. | Select TSZ182IDT only when DC accuracy dominates over speed; avoid for current sensing above 50 kHz. |
| TSB7192IPT | 36 V supply, 20 MHz GBP, 12 V/µs SR, 300 µV max Vio - wider voltage range but lower precision and speed. | Used in industrial 24 V PLC analog I/O; lacks rail-to-rail input and automotive temp grade. | Choose TSB7192IPT for high-voltage industrial signal chains; not drop-in for 5 V automotive designs. |
Compared with TSV794IYPT, TSZ182IDT trades 50 MHz bandwidth for microvolt-level DC stability, while TSB7192IPT sacrifices rail-to-rail operation and automotive qualification for extended supply range - neither matches the combined high-speed, low-noise, and AEC-Q100-ready profile of the TSV794IYPT.

FAQ
What is the maximum capacitive load the TSV794IYPT can drive while remaining stable?
The TSV794IYPT is fully specified for stability with 22 pF load and typically stable up to 1 nF without external compensation. Its internal compensation allows direct connection to ADC inputs and long PCB traces without isolation resistors, provided layout follows good high-frequency practices (short traces, local decoupling, ground plane).
Does the TSV794IYPT require external compensation for unity-gain operation?
No - the TSV794IYPT is unity-gain stable by design. Its internal compensation network guarantees ≥53° phase margin at unity gain into 10 kΩ || 22 pF loads, eliminating need for external components in standard buffer or gain-of-one configurations.
How is unused channel termination handled on the TSV794IYPT?
An unused channel must be configured as either a unity-gain buffer (IN+ tied to valid common-mode voltage, IN– to OUT) or comparator (IN+ and IN– held ≥100 mV apart). Floating inputs cause oscillation, increased supply current, and degraded performance in active channels.
Is the TSV794IYPT pin-compatible with other ST quad op amps like the TSV914?
No - TSV794IYPT uses a unique TSSOP-14 pinout (e.g., VCC+ on pin 4, VCC– on pin 11, NC on pin 14), whereas TSV914 uses SO14 with VCC+ on pin 14 and VCC– on pin 3. Direct replacement requires PCB redesign and validation of bandwidth, noise, and offset performance differences.
