Product details
Overview
TSV774IQ5T from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-bandwidth precision signal conditioning in automotive and industrial systems. It delivers 20 MHz gain bandwidth, 50 µV typical input offset voltage, 13 V/µs slew rate, and operates from 2.0 V to 5.5 V single supply - enabling accurate amplification of low-amplitude sensor signals in current sensing and photodiode interfaces.
For engineers reviewing the TSV774IQ5T datasheet, TSV774IQ5T pinout, TSV774IQ5T application, or TSV774IQ5T equivalent, key selection criteria include its 4-channel integration in QFN16, -40 °C to +125 °C automotive-grade temperature range, 4 kV HBM ESD rating, and verified stability with 47 pF capacitive loads - critical for A/D converter buffering and active filter design.
Technical Context
The TSV774IQ5T employs a dual-input-stage architecture supporting rail-to-rail common-mode input range (VCC− −0.2 V to VCC+ +0.1 V), with optimal precision maintained over VCC− −0.1 V to VCC+ −1.8 V. Its unity-gain-stable 20 MHz GBW and 13 V/µs slew rate enable faithful reproduction of fast transients in high-side current sensing and photodiode amplification.
Each channel features 2 pA max input bias current, 7 nV/√Hz input voltage noise at 10 kHz, and 95–110 dB open-loop gain at 25 °C - ensuring minimal DC error and high dynamic fidelity across 2.0–5.5 V supply operation and full automotive temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV794IPT | 50 MHz GBW, 1.8 mA/ch supply current, 11 V/µs slew rate | Better for wideband active filters but higher power; less suitable for battery-powered sensors | Select when bandwidth >30 MHz required and supply current budget allows ≥1.8 mA/ch |
| LMV774MTX/NOPB | 17 MHz GBW, 1.2 mA/ch, 1.2 mV max VOS, non-automotive grade | Lacks AEC-Q100 qualification and 4 kV HBM; lower accuracy limits use in precision current sensing | Select only for cost-sensitive industrial controls where automotive reliability is not mandated |
Compared with TSV774IQ5T, TSV794IPT trades lower power and tighter offset for significantly higher bandwidth, while LMV774MTX/NOPB offers lower cost but sacrifices automotive qualification, ESD robustness, and DC precision - making TSV774IQ5T the optimal choice for safety-critical, high-accuracy, thermally demanding applications.

FAQ
What is the maximum capacitive load the TSV774IQ5T can drive without external compensation?
The TSV774IQ5T is fully characterized and stable with 47 pF capacitive load in unity-gain configuration, as confirmed in DS13842 Rev 7 Section 3 and Figure 29. For loads exceeding 47 pF, a series isolation resistor (10–33 Ω) between output and load is recommended to maintain phase margin above 50° and prevent overshoot.
Does the TSV774IQ5T require external power supply decoupling, and if so, what is the recommended layout?
Yes - a 100 nF X7R ceramic capacitor must be placed within 1 mm of pins 2 (VCC+) and 11 (VCC−), with short, low-inductance traces to the QFN16 thermal pad (connected to VCC−). This minimizes supply impedance at high frequencies and prevents oscillation, especially critical for 20 MHz operation and EMI immunity per Section 5.4 of DS13842.
How should unused op amp channels be terminated to prevent instability or excess current draw?
Unused channels must be configured either as unity-gain buffers (IN+ tied to any valid common-mode voltage, IN− to OUT) or as comparators (IN+ and IN− held ≥100 mV apart within Vicm range). Leaving inputs floating or shorting them together risks internal oscillation and increased ICC, as specified in Section 5.3 of the datasheet.
Is the TSV774IQ5T pin-compatible with other STMicroelectronics quad op amps like the TSV794?
No - TSV774IQ5T (QFN16) uses a unique pinout incompatible with TSV794IPT (TSSOP14) and TSV772 variants. Pin mapping differs for supply rails, input pairs, and output ordering; PCB redesign is required for substitution. Refer to Tables 3–4 and Figures 3–4 in DS13842 for authoritative pin assignments.
