Product details
Overview
TSV911ILT from STMicroelectronics is a single rail-to-rail input/output operational amplifier in SOT23-5 package, designed for low-voltage precision signal conditioning. It delivers 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 operates from 2.5 V to 5.5 V supply - enabling high-fidelity sensor interfacing in space-constrained portable medical and automotive systems.
For engineers reviewing the TSV911ILT datasheet, TSV911ILT pinout, TSV911ILT application, or TSV911ILT equivalent, key selection criteria include its rail-to-rail I/O swing at 2.5 V supply, ultra-low input bias current for high-impedance source compatibility, unity-gain stability with capacitive load drive up to 100 pF, and AEC-Q100 qualified variants for automotive use cases.
Technical Context
The TSV911ILT 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 without external components while maintaining 45° phase margin into 100 pF loads.
It achieves 8 MHz gain-bandwidth at 1.1 mA supply current, delivering 35 mA output drive capability with ±15 mV high/low-level output voltage error (RL = 10 kΩ) - supporting active filtering and buffered analog front-ends where power efficiency and output linearity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~100 kHz with G = 100, suitable for anti-aliasing and reconstruction filters. |
| Input bias current | 1 pA typ. - preserves signal integrity when amplifying from high-impedance sources like pH electrodes or photodiode transimpedance nodes. |
| Input offset voltage | 1.5 mV max (A grade) - limits DC error to ≤0.3% of full-scale in 0–5 V measurement ranges without trimming. |
| Slew rate | 4.5 V/μs - supports 10 kHz full-power sine wave output at 20 Vpp without distortion in unity-gain buffer configurations. |
| Supply voltage range | 2.5 V to 5.5 V - compatible with single-cell Li-ion (3.0–3.7 V), 3.3 V logic rails, and dual-supply industrial sensors. |
| Output drive current | ±35 mA - directly drives 100 Ω loads or multiple 10 kΩ inputs without external buffers in data acquisition modules. |
| ESD protection | ≥5 kV HBM - withstands handling and board-level electrostatic discharge in handheld diagnostic equipment assembly. |
Pinout & Package
SOT23-5 package: 2.9 mm × 1.6 mm × 1.1 mm body, surface-mount, moisture sensitivity level 1, RoHS-compliant ECOPACK2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage 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 in dual-supply configs. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node (1 pA bias); accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V. |
| 4 (VCC+) | Positive supply | Accepts 2.5–5.5 V; decoupling capacitor (10 nF) required adjacent to this pin per layout guidelines. |
| 5 (IN−) | Inverting input | High-impedance CMOS node; used for feedback network connection in standard op-amp configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.5 V systems - e.g., 0–2.5 V sensor output digitized by 12-bit SAR ADC without level-shifting. |
| Unity-gain stable | Eliminates need for external compensation components in buffer, integrator, or active filter designs - reducing BOM count and PCB area. |
| Low power consumption | 820 µA typical ICC allows continuous operation for >1 year on a 200 mAh coin cell in portable ECG monitors. |
| High output current | 35 mA drive supports direct interface to LED indicators, analog multiplexer control lines, or low-impedance DAC outputs. |
| Latch-up immunity | 200 mA rating prevents destructive failure during transient overvoltage events in automotive battery monitoring circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911RILT | Different pinout (OUT/VCC+/IN+/VCC−/IN− vs. OUT/VCC−/IN+/VCC+/IN−); identical electrical specs. | Requires PCB layout revision; not drop-in compatible despite same footprint and performance. | Select only when redesigning for optimized routing - e.g., separating power and input traces in noise-sensitive layouts. |
| TSV991ILT | Higher GBP (20 MHz), higher ICC (1.4 mA), same SOT23-5 package and rail-to-rail I/O. | Better for wideband active filters or fast-settling multiplexed DAQ; trades power for bandwidth. | Choose when >10 MHz closed-loop bandwidth is required and 600 µA extra supply current is acceptable. |
Compared with TSV911RILT, the TSV911ILT offers proven pin compatibility with legacy SOT23-5 op amp footprints; versus TSV991ILT, it provides optimal balance of bandwidth, power, and cost for sub-100 kHz precision signal chains in battery-constrained devices.

FAQ
What is the maximum capacitive load the TSV911ILT can drive without external compensation?
The TSV911ILT is specified to drive up to 100 pF capacitive loads in unity-gain follower configuration without oscillation, per Figure 10 and Section 5.1 of DS4899. For loads exceeding 100 pF, a series resistor (typically 10–100 Ω) between output and load is recommended to restore phase margin above 45°.
Does the TSV911ILT support true single-supply operation down to 2.5 V?
Yes - the TSV911ILT operates from 2.5 V to 5.5 V with rail-to-rail input common-mode range extending 0.1 V beyond both supply rails and rail-to-rail output swing within 15 mV of each rail (RL = 10 kΩ), enabling direct interfacing with 2.5 V ADCs and microcontrollers.
How does the input offset voltage drift behave over temperature?
The TSV911ILT exhibits a maximum input offset voltage drift of 5 µV/°C (ΔVio/ΔT), as specified in Tables 3–5. At 125 °C ambient, total offset remains ≤3 mV for A-grade parts - verified by Figure 3 showing distribution centered near 0 mV even at elevated temperature.
Is the SOT23-5 package of TSV911ILT lead-free and RoHS compliant?
Yes - the TSV911ILT uses STMicroelectronics' ECOPACK2 packaging, which meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin terminations and halogen-free molding compound certified per IEC 61249-2-21.
