Product details
Overview
TSV911IYLT from STMicroelectronics is a single-channel, rail-to-rail input/output operational amplifier optimized for automotive-grade applications. It operates from 2.5 V to 5.5 V, delivers 8 MHz gain-bandwidth product, consumes only 820 µA typical supply current, and features 1.5 mV max input offset voltage (A grade) with 1 pA typical input bias current. It is used in sensor signal conditioning within automotive body control modules.
For engineers reviewing the TSV911IYLT datasheet, TSV911IYLT pinout, TSV911IYLT application, or TSV911IYLT equivalent, key selection criteria include its AEC-Q100 qualified SOT23-5 automotive package, rail-to-rail operation at low supply voltage, ultra-low input bias current for high-impedance sensor interfaces, and guaranteed 8 MHz bandwidth with unity-gain stability.
Technical Context
The TSV911IYLT employs a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures unity-gain stability across 2.5–5.5 V supply and −40 °C to +125 °C temperature range.
It achieves 4.5 V/µs slew rate and 8 MHz gain-bandwidth product while driving up to ±35 mA output current into loads ≥600 Ω. Input offset voltage drift is specified at 5 µV/°C, supporting precision DC-coupled amplification in automotive ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V rails without LDO. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~100 kHz with gain ≥10, suitable for active filtering. |
| Input Bias Current | 1 pA typ. - preserves signal integrity in high-impedance pH, thermopile, or piezoelectric sensor front-ends. |
| Input Offset Voltage | 1.5 mV max (A grade) - ensures ≤0.3% error in 500 mV full-scale medical or automotive sensor outputs. |
| Slew Rate | 4.5 V/µs - supports clean 10 kHz sine wave output at 2 Vpp without distortion in battery-powered instrumentation. |
| Output Drive | ±35 mA - directly drives LED indicators, small solenoids, or ADC reference buffers without external transistors. |
| ESD Protection | ≥5 kV HBM - meets automotive board-level ESD robustness requirements per ISO 10605. |
Pinout & Package
SOT23-5 package: compact 2.9 mm × 1.6 mm surface-mount outline with exposed pad (not internally connected; may be tied to VCC− or left floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing; capable of sourcing/sinking ±35 mA into resistive loads. |
| 2 (VCC−) | Negative supply | Ground reference for single-supply operation; connects to system GND or negative rail. |
| 3 (IN+) | Non-inverting input | High-impedance node (1 pA bias); accepts signals from 0.1 V below VCC− to 0.1 V above VCC+. |
| 4 (VCC+) | Positive supply | Accepts 2.5–5.5 V; decoupling capacitor required within 2 mm for stability. |
| 5 (IN−) | Inverting input | High-impedance feedback node; matched to IN+ for <3 µV input offset in A-grade devices. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems - output swings within 15 mV of rails at 10 kΩ load. |
| Unity-gain stable | Eliminates need for external compensation; supports buffer, integrator, and active filter topologies without risk of oscillation. |
| AEC-Q100 qualified | Validated for automotive temperature range (−40 °C to +125 °C) and lifetime reliability per Grade 1 stress testing. |
| Low noise | 21 nV/√Hz at 10 kHz - preserves SNR in amplification stages preceding 16-bit SAR ADCs in telematics ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ILT | Same silicon, commercial-grade (−40 °C to +125 °C), non-AEC-Q100 qualified; identical electrical specs. | Approved for industrial but not automotive production; lacks AEC screening and traceability documentation. | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays ≤105 °C. |
| MCP6001T-E/OT | Lower GBP (1 MHz), higher Vio (2.5 mV max), 100x higher Iib (100 pA typ.), same SOT23-5 footprint. | Not qualified for automotive; limited bandwidth restricts use in active filters above 10 kHz. | Choose only for non-safety-critical consumer applications where ultra-low power (<1 µA sleep) is prioritized over precision. |
Compared with TSV911IYLT, TSV911ILT offers identical performance at lower cost but lacks AEC-Q100 validation for automotive deployment, while MCP6001T-E/OT trades bandwidth, offset, and bias current for broader availability and lower unit price in non-automotive designs.

FAQ
Is TSV911IYLT pin-compatible with other SOT23-5 op amps like LMV321 or MCP6001?
Yes - TSV911IYLT uses the standard SOT23-5 pinout (OUT/VCC−/IN+/VCC+/IN−), matching LMV321IDBVR and MCP6001T-E/OT. However, its 8 MHz bandwidth and 1 pA bias current exceed both alternatives, so layout parasitics must be minimized to maintain stability at higher frequencies.
What is the maximum capacitive load the TSV911IYLT can drive without external compensation?
The TSV911IYLT remains stable driving up to 100 pF capacitive load in unity-gain follower configuration, per datasheet Figure 10 and Section 5.1. For loads >100 pF, a 10–47 Ω series resistor between output and load is recommended to restore phase margin above 45°.
Does the exposed pad on the SOT23-5 package require thermal or electrical connection?
No - the exposed pad in the TSV911IYLT SOT23-5 package is not internally connected (per datasheet Section 6.1 and footnote on page 15). It may be left floating or soldered to VCC− for minor thermal improvement, but no electrical function is assigned.
How does the TSV911IYLT's input offset voltage drift affect accuracy in automotive temperature sensing?
With ∆Vio/∆T = 5 µV/°C, over a −40 °C to +125 °C range (165 °C span), worst-case drift is 825 µV - contributing <0.17% error in a 500 mV full-scale thermistor bridge output. This is well within AEC-Q100 Class 0 sensor interface requirements.
