Product details
Overview
TSV771IYLT from STMicroelectronics is a single-channel, rail-to-rail input/output operational amplifier optimized for high-bandwidth precision signal conditioning. It delivers 20 MHz gain bandwidth, 13 V/µs slew rate, 50 µV typical input offset voltage, and operates from 2.0 V to 5.5 V supply - enabling accurate low-side current sensing in automotive power management systems.
For engineers reviewing the TSV771IYLT datasheet, TSV771IYLT pinout, TSV771IYLT application, or TSV771IYLT equivalent, key selection criteria include its 200 µV max input offset over –40 °C to +125 °C, 2 pA max input bias current, 7 nV/√Hz noise at 10 kHz, rail-to-rail operation with 47 pF capacitive load compatibility, and SOT23-5 packaging for space-constrained PCB layouts.
Technical Context
The TSV771IYLT employs a unity-gain-stable architecture with a 20 MHz GBP and 48–50° phase margin across supply voltages (2.0–5.5 V), ensuring stability into 47 pF loads without external compensation. Its dual-input-pair rail-to-rail input stage supports common-mode range from VCC− −0.2 V to VCC+ +0.1 V, with optimal precision maintained between VCC− −0.1 V and VCC+ −1.8 V.
It features 4 kV HBM ESD tolerance, guaranteed operation over –40 °C to +125 °C, and low 2.1 mA supply current per channel at 5 V - making it suitable for always-on automotive sensor interfaces and solar-powered A/D buffer stages where accuracy, speed, and supply flexibility are co-critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 20 MHz - enables stable closed-loop operation up to ~1.5 MHz at gain = 10 without peaking. |
| Input Offset Voltage | 200 µV max (–40 °C to +125 °C) - ensures ≤0.2% error in 100 mV full-scale current-sense applications. |
| Slew Rate | 13 V/µs - supports clean 10 MHz small-signal step response with <470 ns settling to 0.01%. |
| Input Bias Current | 2 pA max (25 °C) - minimizes voltage error across high-impedance photodiode or filter networks. |
| Noise Density | 7 nV/√Hz at 10 kHz - preserves SNR in >100 kHz signal chains such as active filters or ADC drivers. |
| Supply Range | 2.0 V to 5.5 V - interoperable with Li-ion, 3.3 V MCU I/O, and legacy 5 V industrial rails. |
| ESD Tolerance | 4 kV HBM - meets automotive module-level robustness requirements without external protection. |
Pinout & Package
TSV771IYLT is housed in a compact SOT23-5 package (2.9 mm × 1.6 mm × 1.1 mm), optimized for high-density automotive and portable designs. The exposed pad is not present in this variant - thermal dissipation relies on standard PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output channel | Capable of sourcing/sinking ≥45 mA; rail-to-rail swing enables full dynamic range utilization with 47 pF load. |
| 2 (VCC−) | Negative supply voltage | Reference ground node; must be connected directly to low-impedance GND plane for noise immunity. |
| 3 (IN+) | Non-inverting input | High-impedance node (2 pA bias); used for reference-driven configurations like non-inverting buffers. |
| 4 (IN−) | Inverting input | Differential input node; accepts feedback network for precision gain-setting in transimpedance or difference amplifiers. |
| 5 (VCC+) | Positive supply voltage | Accepts 2.0–5.5 V; decoupling capacitor (100 nF) required within 2 mm for stability at 20 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal capture from 0 V to VCC in single-supply systems - critical for low-voltage solar MPPT and battery monitoring. |
| 20 MHz GBP with unity-gain stability | Eliminates need for external compensation in high-speed buffers, reducing BOM count and layout sensitivity. |
| 7 nV/√Hz input voltage noise (10 kHz) | Preserves resolution in photodiode preamps and strain-gauge bridges where signal amplitudes are sub-mV. |
| 47 pF capacitive load drive capability | Directly interfaces with SAR ADC inputs without isolation resistor - maintains DC accuracy and transient fidelity. |
| Automotive-grade temperature range | Qualified per AEC-Q100 Grade 1 (–40 °C to +125 °C), supporting under-hood and ADAS sensor signal chains. |
Applications
| High-Bandwidth Current Sensing | Photodiode Signal Amplification |
|---|---|

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 |
|---|---|---|---|
| TSV791ICT | 50 MHz GBP, 22 V/µs slew rate, 100 µV max Vio, but higher 3.5 mA ICC and no AEC-Q100 qualification. | Better for wideband active filters; unsuitable for automotive temperature or reliability requirements. | Select only for non-automotive, higher-speed applications where supply current and qualification are secondary. |
| LMV791MMX/NOPB | 17 MHz GBP, 10 V/µs slew rate, 250 µV max Vio, 1.2 mA ICC, industrial temp range only (–40 °C to +125 °C not guaranteed). | Lower cost for consumer-grade current sensing; lacks automotive qualification and 20 MHz bandwidth headroom. | Consider for cost-sensitive industrial or white goods where AEC-Q100 and 20 MHz performance are not mandatory. |
Compared with TSV771IYLT, TSV791ICT trades automotive qualification and efficiency for higher speed, while LMV791MMX/NOPB sacrifices bandwidth and offset accuracy for lower cost and power - making TSV771IYLT the optimal balance for automotive-qualified, precision high-speed buffering.

FAQ
What is the maximum capacitive load the TSV771IYLT can drive without external compensation?
The TSV771IYLT is fully characterized and stable driving up to 47 pF capacitive load in unity-gain configuration, as verified in DS13842 Rev 7. For loads exceeding 47 pF, a series output resistor (RISO = 10–33 Ω) is recommended to suppress peaking and ringing while preserving DC accuracy - confirmed by Figure 29 and Section 5.6 of the datasheet.
Does the TSV771IYLT support true rail-to-rail input at 2.0 V supply?
Yes - the input common-mode range extends from VCC− −0.2 V to VCC+ +0.1 V across the full 2.0–5.5 V supply range and –40 °C to +125 °C temperature range. At 2.0 V supply, this translates to –0.2 V to +2.1 V, enabling direct interfacing with sensors operating near ground or above VCC, as specified in Table 6 and Section 5.1.
Is the TSV771IYLT qualified for automotive applications?
Yes - the TSV771IYLT is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C), with full characterization including 4 kV HBM ESD, extended temperature electrical testing, and reliability stress validation. This qualification is explicitly stated in the "Automotive grade versions available" feature list and supported by DS13842 revision history and ST's official product brief.
How does the input offset voltage drift behave over temperature?
The TSV771IYLT exhibits ±5 µV/°C maximum input offset voltage drift over –40 °C to +125 °C, calculated per Equation (1) in Section 5.2. This results in ≤±0.75 mV total offset shift across the full range - a predictable, linear contribution that system-level calibration can compensate, unlike nonlinear drift mechanisms found in lower-grade amplifiers.
