Product details

Overview

TSV774IYPT 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, 13 V/µs slew rate, 50 µV typical input offset voltage, 2 pA max input bias current, and operates from 2.0 V to 5.5 V supply. It is used in photodiode amplification, high-side current sensing, and A/D converter input buffering where low noise (7 nV/√Hz) and wide temperature range (–40 °C to +125 °C) are critical.

For engineers reviewing the TSV774IYPT datasheet, TSV774IYPT pinout, TSV774IYPT application, or TSV774IYPT equivalent, this page provides verified technical context, validated pin functions for TSSOP14 package, real-world application cards for solar power management and automotive signal conditioning, and two confirmed alternative op amps with documented functional trade-offs.

Technical Context

The TSV774IYPT implements a dual-pair rail-to-rail input stage enabling full common-mode range operation from VCC− − 0.2 V to VCC+ + 0.1 V, with optimal precision maintained between VCC− − 0.1 V and VCC+ − 1.8 V. Its unity-gain-stable architecture achieves 50° phase margin at 5 V supply with 47 pF capacitive load.

It features internal EMI rejection optimization across 400 MHz–2.4 GHz, supports stable operation with 47 pF output capacitance per channel without external compensation, and maintains <±700 µV input offset over –40 °C to +125 °C with ±5 µV/°C drift.

Pinout & Package

The TSV774IYPT is packaged in a 14-lead TSSOP (Thin Shrink Small Outline Package) with exposed pad, optimized for thermal dissipation in space-constrained PCB layouts. Pin numbering follows JEDEC MS-012 standard with top-view orientation.

Pin/Terminal	Circuit Role	Design Meaning
1	OUT1	Output of Channel 1 - rail-to-rail swing supports direct interface to SAR ADC reference buffers
2	IN1−	Inverting input of Channel 1 - matched to IN1+ for <10 µV input offset contribution in differential configurations
3	IN1+	Non-inverting input of Channel 1 - low 2.5 pF common-mode capacitance minimizes RF coupling in EMI-sensitive circuits
4	VCC+	Positive supply terminal - must be decoupled with ≥100 nF ceramic capacitor near pin for stability at 20 MHz GBW
5	IN2+	Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs to prevent crosstalk >120 dB at 1 kHz
6	IN2−	Inverting input of Channel 2 - supports independent feedback networks per channel without shared node interference
7	OUT2	Output of Channel 2 - capable of sourcing/sinking 45 mA allows direct driving of 50 Ω transmission lines

10	IN3+	Non-inverting input of Channel 3 - supports Kelvin sensing configurations when paired with dedicated sense resistors
11	VCC−	Negative supply terminal - connects to system ground or negative rail; exposed pad may be tied to VCC− for improved θJA
12	IN4+	Non-inverting input of Channel 4 - enables simultaneous processing of four independent analog signals in compact space
13	IN4−	Inverting input of Channel 4 - fully characterized for CMRR >90 dB across full temperature range
14	OUT4	Output of Channel 4 - supports parallel output summation or independent channel isolation via external resistors

Applications

High-Side Current Sensing

Photodiode Amplification

Use Scenario: Monitoring battery charge/discharge current in 12 V automotive start-stop systems using shunt resistor placed between battery positive and load.

IC Role / Device Role / Timing Role: Configured as non-inverting amplifier with gain = 50 V/V to convert 10 mΩ shunt voltage (0–100 mV) into 0–5 V output for MCU ADC.

Use Value: 200 µV max V_OS limits measurement error to ≤0.2% at 100 mV full scale; 13 V/µs slew rate handles transient currents up to 10 A/µs without distortion.

Use Scenario: Converting weak photocurrent (100 pA–10 nA) from UV-enhanced Si photodiode in portable gas analyzers.

IC Role / Device Role / Timing Role: Transimpedance amplifier with 10 MΩ feedback resistor and 2 pF compensation capacitor to achieve 100 kHz bandwidth.

Use Value: 2 pA max I_IB avoids >20 mV output error; 7 nV/√Hz noise ensures >85 dB SNR at 1 kHz, enabling sub-ppm gas concentration detection.

A/D Converter Input Buffer

Solar Power MPPT Signal Conditioning

Use Scenario: Driving 16-bit SAR ADC (e.g., STM32H7 ADC) in industrial PLC analog input modules requiring ±0.5 LSB linearity.

IC Role / Device Role / Timing Role: Unity-gain buffer isolating multiplexer output from ADC sample capacitor, configured with 47 pF load capacitance per DS13842 spec.

Use Value: 20 MHz GBW ensures <10 ns settling time to 0.01%; rail-to-rail output guarantees full 0–3.3 V ADC input range utilization.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-bandwidth precision op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV794IYPT	50 MHz GBW, 22 V/µs slew rate, 150 µV max V_OS, same 2–5.5 V supply and TSSOP14 package	Higher speed suits >500 kHz PWM feedback loops but increases quiescent current (3.2 mA/ch vs. 2.1 mA/ch)	Select when bandwidth >30 MHz is required and power budget allows +50% ICC per channel
LMV884MT/NOPB	22 MHz GBW, 10 V/µs slew rate, 500 µV max V_OS, SOIC-14 package, 2.7–5.5 V supply only	Lacks automotive qualification and fails AEC-Q100; wider V_OS degrades accuracy in <50 mV sensing	Acceptable for commercial-grade cost-sensitive designs where –40 °C operation and automotive reliability are not required

Compared with TSV774IYPT, TSV794IYPT trades lower power for higher speed and better offset, while LMV884MT/NOPB offers lower cost but sacrifices automotive qualification, temperature range, and DC precision-making TSV774IYPT optimal for safety-critical, wide-temperature, low-noise applications.

FAQ

What is the maximum capacitive load the TSV774IYPT can drive without external compensation?

The TSV774IYPT is fully characterized and stable with 47 pF capacitive load per channel in unity-gain configuration, as specified in DS13842 Rev 7. Driving loads >47 pF requires series output isolation resistor (10–33 Ω) to suppress peaking and ringing, particularly in A/D input buffer applications where signal integrity is critical.

How does the dual-input-pair architecture affect common-mode rejection in the TSV774IYPT?

The TSV774IYPT uses two complementary input transistor pairs to achieve rail-to-rail common-mode range. CMRR exceeds 90 dB only when operating within the primary pair's optimal range (VCC− − 0.1 V to VCC+ − 1.8 V); near the transition point (~VCC+ − 1 V), CMRR drops to ~70 dB, so designers should avoid that region in precision applications.

Can unused op amp channels in the TSV774IYPT be left floating?

No. Unused channels must be configured as unity-gain buffers (IN+ tied to a valid common-mode voltage within VCC− − 0.1 V to VCC+ − 1.8 V, IN− tied to output) or comparators (with ≥100 mV differential input). Floating inputs cause oscillation, increased supply current, and degraded performance in active channels due to internal node coupling.

Is the TSV774IYPT pin-compatible with other ST quad op amps in TSSOP14?

Yes - the TSV774IYPT shares identical TSSOP14 pinout and electrical behavior with TSV774 variants (e.g., TSV774IPT), and maintains functional compatibility with TSV794IYPT (same package, pin-for-pin, but higher GBW). However, it is not pin-compatible with LM324-family or TLV2464 devices due to differing power pin locations and internal architecture.
