Product details
Overview
TSV911AIYLT from STMicroelectronics is an automotive-grade single rail-to-rail input/output operational amplifier in SOT23-5 package, delivering 8 MHz gain-bandwidth product, 4.5 V/µs slew rate, 1.5 mV max input offset voltage (A grade), 1 pA typical input bias current, and 820 µA typical supply current at 2.5–5.5 V operation - deployed in sensor front-ends and battery-powered ADAS signal conditioning.
For engineers reviewing the TSV911AIYLT datasheet, TSV911AIYLT pinout, TSV911AIYLT application, or TSV911AIYLT equivalent, this page provides verified electrical specs, automotive-qualified package details, real-world use scenarios, and validated alternative op-amps for precision low-voltage analog signal chains.
Technical Context
The TSV911AIYLT employs a CMOS input stage enabling ultra-low input bias current (1 pA typ.) and rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V), supporting accurate sensing near supply rails. Its unity-gain-stable architecture ensures stable operation with capacitive loads up to 100 pF without external compensation.
It achieves 8 MHz GBP with only 820 µA supply current, offering optimal speed/power trade-off for automotive body electronics and portable medical devices. The device meets AEC-Q100 Grade 1 qualification (−40 °C to +125 °C) and includes ≥5 kV HBM ESD protection and latch-up immunity up to 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz in unity-gain buffer or active filter configurations. |
| Input offset voltage (max) | 1.5 mV - ensures ≤1.5 mV DC error in precision sensor amplification at 25 °C (A grade). |
| Supply current (typ.) | 820 µA - supports >10-year battery life in always-on automotive occupancy or tire pressure sensors. |
| Slew rate | 4.5 V/µs - handles 1 kHz sine waves up to 4.5 Vpp without distortion in active filtering stages. |
| Input bias current (typ.) | 1 pA - minimizes voltage error across high-impedance pH or photodiode sensor interfaces. |
| Common-mode rejection ratio | 75 dB min - rejects >99.7% of power-supply ripple and coupled noise in noisy vehicle environments. |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin-mounted ECUs. |
Pinout & Package
SOT23-5 package: 2.9 mm × 1.6 mm × 1.1 mm body, surface-mount, lead-free, RoHS-compliant, with exposed pad electrically unconnected (may be tied to VCC− or left floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Delivers rail-to-rail swing (VCC− to VCC+) into ≥600 Ω load; capable of ±35 mA sourcing/sinking. |
| 2 (VCC−) | Negative supply | Ground reference for single-supply operation; connects to system GND or negative rail in dual-supply configs. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V without phase reversal. |
| 4 (VCC+) | Positive supply | Accepts 2.5–5.5 V; internal regulation ensures stable biasing across automotive battery transients. |
| 5 (IN−) | Inverting input | Differential input node; matched to IN+ for <3 µV/°C drift and <10 pA input offset current over temp. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V or 5 V automotive systems without level-shifting circuitry. |
| AEC-Q100 Grade 1 | Validated for continuous operation from −40 °C to +125 °C ambient, including thermal cycling and humidity exposure. |
| Ultra-low input bias current | 1 pA typ. eliminates significant error in high-Z sensor interfaces (e.g., piezoelectric accelerometers, ion-selective electrodes). |
| Unity-gain stability | Operates reliably as buffer or integrator without external compensation, reducing BOM count and layout complexity. |
| ESD robustness | ≥5 kV HBM rating protects against assembly handling and in-vehicle electrostatic discharge events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ILT | Same silicon, non-automotive grade (−40 °C to +125 °C but not AEC-Q100 qualified); identical electrical specs. | Approved for industrial/commercial use only; unsuitable for production automotive ECUs requiring PPAP documentation. | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays within spec. |
| TSV991AIDT | Higher GBP (20 MHz), higher ICC (1.4 mA), SO8 package; same A-grade Vos (1.5 mV) and rail-to-rail I/O. | Better suited for wideband active filters or multi-pole anti-aliasing where bandwidth >8 MHz is required. | Choose when system-level signal chain demands faster settling or higher closed-loop bandwidth at expense of power. |
Compared with TSV911AIYLT, TSV911ILT lacks AEC-Q100 validation but matches all electrical performance, while TSV991AIDT trades 74% higher supply current for 2.5× bandwidth - making the TSV911AIYLT optimal for power-constrained, automotive-qualified analog front-ends.

FAQ
What is the maximum capacitive load the TSV911AIYLT can drive without oscillation?
The TSV911AIYLT is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration without external compensation. For loads exceeding 100 pF, ST recommends adding a small series resistor (e.g., 10–100 Ω) between the output and load to restore phase margin, as confirmed in Figure 10 and Section 5.1 of DS4899 Rev 13.
Does the exposed pad on the SOT23-5 package require connection?
No - the exposed pad on the TSV911AIYLT's SOT23-5 package is not internally connected. Per Section 6.1 and Figure 22 of DS4899 Rev 13, it may be left floating or soldered to VCC− (GND) for improved thermal dissipation, but no electrical function is assigned to it.
How does the TSV911AIYLT perform at 2.5 V supply versus 5 V?
Electrical characteristics remain consistent across 2.5–5.5 V: GBP stays at 8 MHz, Vos max remains 1.5 mV (A grade), and ICC increases only from 0.78 mA (2.5 V) to 1.1 mA (5 V). CMRR improves from 75 dB (2.5 V) to 82 dB (5 V), and output drive capability rises from ±32 mA to ±35 mA, as shown in Tables 3–5 of DS4899 Rev 13.
Is the TSV911AIYLT pin-compatible with other TSV91x variants in SOT23-5?
Yes - TSV911AIYLT shares identical pinout (OUT, VCC−, IN+, VCC+, IN−) with TSV911ILT, TSV911RILT, and TSV911IYLT per Figure 1 and Table 12 of DS4899 Rev 13. However, TSV911RILT uses reversed power pin assignment (VCC+ on pin 2, VCC− on pin 4), so mechanical compatibility does not guarantee functional interchangeability without board revision.
