Product details
Overview
TSV771ILT 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, and ultra-low 50 µV typical input offset voltage - enabling accurate amplification of mV-level sensor signals in automotive current sensing and photodiode interfaces. Packaged in SOT23-5, it operates from 2.0 V to 5.5 V and is qualified for -40 °C to +125 °C operation.
For engineers reviewing the TSV771ILT datasheet, TSV771ILT pinout, TSV771ILT application, or TSV771ILT equivalent, key selection criteria include its 200 µV max input offset, 2 pA max input bias current, 7 nV/√Hz noise at 10 kHz, rail-to-rail swing capability, and guaranteed stability with 47 pF capacitive load - critical for A/D converter buffering and high-side current measurement circuits.
Technical Context
The TSV771ILT employs a dual-input-stage architecture supporting full common-mode range (VCC− −0.2 V to VCC+ +0.1 V), with precision optimized over the low-pair region (VCC− −0.1 V to VCC+ −1.8 V). Its unity-gain-stable design achieves 50° phase margin and 9 dB gain margin at 5 V supply with 47 pF load.
It integrates EMI-hardened input stages delivering >40 dB EMIRR from 400 MHz to 2.4 GHz, and features 4 kV HBM ESD tolerance. The amplifier maintains DC accuracy across temperature via ±5 µV/°C max offset drift and supports stable operation down to 2.0 V supply while retaining 17 MHz min GBP and 9 V/µs min slew rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 20 MHz typ. - enables stable closed-loop operation up to 10 MHz at gain ≥2 without peaking. |
| Input Offset Voltage | 200 µV max - ensures ≤0.2% error amplifying 100 mV input signals at room temperature. |
| Slew Rate | 13 V/µs typ. - supports clean 1 Vpp output at 1 MHz without distortion in unity-gain buffer configuration. |
| Input Bias Current | 2 pA max - prevents significant voltage drop across >1 GΩ photodiode or high-Z sensor sources. |
| Supply Voltage Range | 2.0 V to 5.5 V - compatible with Li-ion, 3.3 V logic, and automotive 5 V domains without level-shifting. |

| Capacitive Load Drive | Stable with 47 pF - eliminates need for external compensation when driving SAR ADC inputs directly. |
Pinout & Package
TSV771ILT is housed in a 5-pin SOT23-5 package with exposed pad (non-connected per datasheet). The compact footprint supports high-density PCB layouts in space-constrained automotive and portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Amplifier output | Drives loads up to 65 mA sink/source; rail-to-rail swing enables direct interface to 12-bit+ SAR ADCs. |
| 2 VCC− | Negative supply | Reference node for single-supply operation; connects to ground in most 2.0–5.5 V applications. |
| 3 IN+ | Non-inverting input | High-impedance node (2 pA bias) - preserves signal integrity in high-Z sensor front-ends. |
| 4 IN− | Inverting input | Accepts feedback networks; supports precision current-sense configurations with matched resistors. |
| 5 VCC+ | Positive supply | Supports operation down to 2.0 V - enables use in energy-harvesting solar power management systems. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened input stage | EMIRR >40 dB (400 MHz–2.4 GHz) - suppresses RF rectification-induced offset shifts in noisy automotive environments. |
| Low thermal drift | ±5 µV/°C max - limits total offset error to <700 µV across −40 °C to +125 °C, enabling uncalibrated operation. |
| High-speed settling | 300 ns to 0.1% (1 Vpp step) - meets timing budgets for multiplexed sensor arrays feeding fast ADCs. |
| Extended temperature qualification | −40 °C to +125 °C - certified for under-hood automotive signal conditioning and industrial motor control feedback loops. |
| Low-noise performance | 7 nV/√Hz at 10 kHz - preserves SNR in photodiode transimpedance amplifiers with >100 kΩ feedback resistors. |
Applications
| High-Side Current Sensing | Photodiode Signal Amplification |
|---|---|
Use Scenario: Monitoring battery charge/discharge current in EV BMS using shunt resistor placed between battery positive terminal and load. IC Role / Device Role / Timing Role: Precision difference amplifier configured as current-sense amplifier with gain = 50 V/V, rejecting common-mode voltage up to 45 V. Use Value: 200 µV max offset ensures <10 mA absolute error at 20 A full-scale, while 20 MHz bandwidth captures transient fault currents. | Use Scenario: Converting weak photocurrent (nA–µA) from UV/IR detection diodes into measurable voltage for spectral analysis. IC Role / Device Role / Timing Role: Transimpedance amplifier with 1 MΩ feedback resistor, leveraging rail-to-rail output to maximize dynamic range at 3.3 V supply. Use Value: 2 pA max input bias avoids loading high-impedance diodes; 7 nV/√Hz noise enables detection of sub-nW optical signals. |
| A/D Converter Input Buffer | Automotive Signal Conditioning |
Use Scenario: Driving 12-bit SAR ADC inputs in portable medical devices where supply is constrained to 2.5 V. IC Role / Device Role / Timing Role: Unity-gain buffer isolating ADC sample-and-hold capacitor (typically 10–20 pF) from source impedance. Use Value: Stable with 47 pF load and 13 V/µs slew rate ensures <0.1% settling within 300 ns - meeting 1 MSPS sampling requirements. | Use Scenario: Amplifying wheel speed sensor outputs in ABS modules exposed to under-hood temperatures up to 125 °C. IC Role / Device Role / Timing Role: Low-drift instrumentation amplifier front-end stage, rejecting EMI from ignition systems and solenoid drivers. Use Value: 4 kV HBM ESD rating and >40 dB EMIRR prevent latch-up or offset shift during load-dump transients. |
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 |
|---|---|---|---|
| TSV791ILT | 50 MHz GBW, 500 µV max Vio, same SOT23-5 package | Better for >20 MHz closed-loop bandwidth needs; higher offset reduces DC accuracy in precision current sensing | Select when bandwidth >30 MHz required and offset <100 µV not mandatory |
| OPA333AIDBVR | Zero-drift architecture, 10 µV max Vio, 350 kHz GBW, SOT23-5 | Superior DC accuracy but insufficient bandwidth for >100 kHz photodiode or current-sense applications | Select only for ultra-low-offset, low-frequency (<50 kHz) sensor buffering |
Compared with TSV771ILT, TSV791ILT trades offset voltage for bandwidth - suitable for wideband active filters but less accurate for mV-level current measurement; OPA333AIDBVR offers microvolt-level DC precision but lacks the 20 MHz response needed for fast transient capture in automotive or power management systems.

FAQ
What is the maximum capacitive load the TSV771ILT can drive without external compensation?
The TSV771ILT is fully characterized and stable with up to 47 pF capacitive load in unity-gain configuration, as verified in the official datasheet (DS13842 Rev 7, page 7). This allows direct connection to typical SAR ADC input capacitors without added series resistance or feedback compensation networks.
Does the TSV771ILT support true rail-to-rail input with 2.0 V supply?
Yes - the TSV771ILT guarantees rail-to-rail input operation from VCC− −0.2 V to VCC+ +0.1 V across the full supply range (2.0 V to 5.5 V) and temperature range (−40 °C to +125 °C), enabling full utilization of the input common-mode range even at minimum supply voltage.
How does the TSV771ILT's EMI rejection compare to standard op amps?
The TSV771ILT features dedicated EMI-hardened input circuitry achieving >40 dB EMIRR from 400 MHz to 2.4 GHz - significantly exceeding typical general-purpose op amps (<20 dB). This is validated per ESDA-JS-001 and AEC-Q100 standards, making it suitable for automotive environments with strong RF fields.
Can the TSV771ILT be used in single-supply photodiode transimpedance applications?
Yes - its rail-to-rail output, 2 pA max input bias current, and 7 nV/√Hz noise at 10 kHz make it ideal for single-supply photodiode amplifiers. When biased with VCC− = GND and VCC+ = 3.3 V, it delivers full 0–3.3 V output swing while preserving signal fidelity from nA-level photocurrents.
