Product details
Overview
TSV911AILT from STMicroelectronics is a single-channel rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth product, 4.5 V/µs slew rate, and 1.5 mV max input offset voltage (A grade) while consuming only 820 µA typical supply current at 2.5–5.5 V operation - enabling precision signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV911AILT datasheet, TSV911AILT pinout, TSV911AILT application, or TSV911AILT equivalent, key selection criteria include its rail-to-rail I/O swing, ultra-low 1 pA input bias current, unity-gain stability with capacitive loads up to 100 pF, and AEC-Q100-qualified variants for automotive use cases requiring robustness across –40 °C to 125 °C.
Technical Context
This op amp employs a CMOS input stage to achieve 1 pA typical input bias current and rail-to-rail input common-mode range extending 0.1 V beyond supply rails. Its internal compensation ensures unity-gain stability without external components, supporting direct use in voltage followers and active filters.
The device features a high-output-current architecture delivering ±35 mA into resistive loads, with output swing within 15 mV of each rail at 10 kΩ load. Its 8 MHz GBP and 4.5 V/µs slew rate enable accurate amplification of signals up to ~1 MHz with minimal distortion (0.0004% THD+N at 1 kHz, 5 V supply).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports stable closed-loop gain ≥1 up to ~1 MHz with <1° phase error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ILT | Standard grade (7.5 mV max Vos vs. 1.5 mV), same pinout and specs otherwise | Cost-sensitive industrial sensing where <0.5% DC accuracy is acceptable | Select when offset-critical medical or precision metrology requirements do not apply |
| MCP6001T-E/OT | Lower GBP (1 MHz), higher Vos (2.5 mV), but lower quiescent current (100 µA) | Ultra-low-power IoT endpoints prioritizing battery life over bandwidth or precision | Choose only if 1 MHz bandwidth suffices and 820 µA draw is prohibitive |
Compared with TSV911AILT, TSV911ILT trades guaranteed low offset for cost reduction without sacrificing speed or drive strength, while MCP6001T-E/OT offers deeper power savings at the expense of bandwidth and DC accuracy - making TSV911AILT optimal for applications demanding simultaneous precision, speed, and rail-to-rail operation in compact form factors.

FAQ
What is the maximum capacitive load the TSV911AILT can drive without external compensation?
The TSV911AILT is unity-gain stable and can drive up to 100 pF capacitive loads directly in follower configuration without oscillation, as verified in the datasheet's Figure 10 and application note section 5.1. For loads exceeding 100 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended to maintain phase margin above 45°.
Does the TSV911AILT support true single-supply operation down to 2.5 V?
Yes - the TSV911AILT operates from 2.5 V to 5.5 V with rail-to-rail input and output. At 2.5 V supply, its input common-mode range extends from –0.1 V to +2.6 V, and output swings within 15 mV of both rails under 10 kΩ load, enabling full dynamic range utilization in single-cell Li-ion or 2.5 V logic systems.
How does the A-grade (TSV911AILT) differ from standard-grade (TSV911ILT) in practical design?
The A-grade guarantees ≤1.5 mV input offset voltage at 25 °C (vs. ≤7.5 mV for standard grade), reducing worst-case DC error by 5× in precision sensor interfaces. This directly improves accuracy in applications like medical front-ends or calibrated gas sensors where offset drift must remain below 0.3% of full-scale output.
Is the SOT23-5 package of TSV911AILT pin-compatible with other ST op amps?
Yes - the TSV911AILT uses the industry-standard SOT23-5 pinout (OUT, V–, IN+, V+, IN–), matching ST's TSV911ILT, TSV911RILT, and compatible with TI's OPA316 and ADI's ADA4805-1. This allows drop-in replacement during prototyping or qualification without PCB redesign.
