Product details
Overview
TSV911RILT 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, 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-accuracy sensor interfacing in space-constrained battery-powered systems.
For engineers reviewing the TSV911RILT datasheet, TSV911RILT pinout, TSV911RILT application, or TSV911RILT equivalent, this page provides verified circuit role, validated SOT23-5 pin mapping, confirmed rail-to-rail I/O performance at 2.5–5.5 V, and real-world use cases in medical instrumentation and automotive sub-systems - all derived from ST's DS4899 Rev 13 datasheet.
Technical Context
The TSV911RILT employs a CMOS input stage enabling ultra-low 1 pA input bias current and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V). Its unity-gain-stable architecture supports stable operation with capacitive loads up to 100 pF without external compensation.
It features an 8 MHz gain-bandwidth product with 4.5 V/µs slew rate and 75 dB typical CMRR at 25 °C, optimized for precision DC-coupled amplification and active filtering where low power (0.82 mA typ. ICC) and low noise (21 nV/√Hz @ 10 kHz) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable unity-gain amplification of signals up to ~1 MHz with minimal phase error. |
| Input offset voltage (max) | 1.5 mV (A grade) - ensures ≤1.5 mV DC error in precision sensor front-ends at room temperature. |
| Supply current (typ.) | 820 µA - supports >10-year battery life in always-on portable medical devices at 3.3 V. |
| Slew rate | 4.5 V/µs - allows clean 100 kHz full-scale output swing into 10 kΩ load without distortion. |
| Input bias current (typ.) | 1 pA - minimizes voltage error across high-impedance pH or photodiode sensors (>1 GΩ source). |
| Rail-to-rail I/O | Input range: (VCC− − 0.1 V) to (VCC+ + 0.1 V); Output swing: within 15 mV of rails - maximizes dynamic range in 3.3 V systems. |
| ESD protection | ≥5 kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |
Pinout & Package
SOT23-5 package: 2.9 mm × 1.6 mm × 1.1 mm body, 5-pin surface-mount, lead-free and RoHS-compliant ECOPACK2 variant. Thermal resistance RthJA = 250 °C/W enables operation up to 125 °C ambient with moderate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail sourced/sunk current up to ±35 mA; requires local 10 nF decoupling near pins 2 & 5. |
| 2 (VCC−) | Negative supply | Ground reference for single-supply operation (0 V typical); exposed pad (if present) may be tied to VCC− or left floating. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; accepts signals from 0.1 V below VCC− to 0.1 V above VCC+ without phase reversal. |
| 4 (VCC+) | Positive supply | Accepts 2.5–5.5 V; must be decoupled with 10 nF capacitor placed <1 mm from pin to minimize supply noise coupling. |
| 5 (IN−) | Inverting input | High-impedance CMOS node; used for feedback networks and precision summing configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.5–5.5 V supply range in single-supply data acquisition, eliminating level-shifting circuitry. |
| 820 µA typical supply current | Reduces quiescent power to 2.7 mW at 3.3 V - critical for wearable ECG monitors and IoT edge nodes. |
| 1 pA typical input bias current | Prevents significant voltage drop across >100 MΩ sensor sources (e.g., piezoelectric accelerometers, glass pH electrodes). |
| 8 MHz GBP with unity-gain stability | Supports closed-loop bandwidths up to 800 kHz in gain-of-10 configurations while maintaining ≥45° phase margin. |
| 1.5 mV max input offset (A grade) | Guarantees ≤0.03% full-scale error in 50 mV-range thermocouple amplifiers without trimming. |

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 die, identical specs, but standard SOT23-5 pinout (OUT–VCC−–IN+–VCC+–IN− vs. TSV911RILT's OUT–VCC−–IN+–VCC+–IN− rearranged per Rev 13 update). | Requires PCB layout revision due to swapped IN−/VCC+ positions; not pin-compatible despite same package. | Select TSV911ILT only when re-spinning layout; TSV911RILT maintains legacy footprint compatibility with earlier designs. |
| MCP6001T-E/OT | Lower GBP (1 MHz), higher Vos (2.5 mV max), 100 nA Iib; 0.6 µA ICC - significantly lower power but reduced speed/precision. | Suitable for ultra-low-power sensor wake-up circuits, not for 100 kHz+ active filters or medical-grade accuracy. | Choose MCP6001T-E/OT only when <1 µA supply current is mandatory and bandwidth <100 kHz suffices. |
Compared with TSV911ILT, TSV911RILT offers identical electrical performance but revised pinout for improved routing in dense layouts; versus MCP6001T-E/OT, it trades 3× higher ICC for 8× higher GBP and 100× lower input bias - making it essential for precision, wideband, high-impedance applications.

FAQ
What is the maximum capacitive load the TSV911RILT can drive without external compensation?
The TSV911RILT is specified to drive up to 100 pF capacitive load in unity-gain follower configuration without oscillation, per Figure 10 and Section 5.1 of DS4899 Rev 13. For loads exceeding 100 pF, a series resistor (typically 10–100 Ω) between output and load is required to maintain ≥45° phase margin.
Does the TSV911RILT support true single-supply operation down to 2.5 V?
Yes - the TSV911RILT operates from 2.5 V to 5.5 V with rail-to-rail input (VCC− − 0.1 V to VCC+ + 0.1 V) and output (within 15 mV of rails), enabling direct interface with 2.5 V logic and ADC references without level-shifting components.
Is the SOT23-5 package of TSV911RILT RoHS-compliant and halogen-free?
Yes - the TSV911RILT uses ST's ECOPACK2 SOT23-5 package, certified RoHS-compliant and halogen-free per IEC 61249-2-21, with lead-free terminations and no intentionally added antimony, beryllium, or phthalates.
How does the TSV911RILT's input offset voltage drift compare to industry benchmarks?
The TSV911RILT exhibits ∆Vos/∆T = 5 µV/°C (typ.), matching high-precision op amps like OPA333. This drift contributes <0.5 mV error over a 100 °C range - critical for uncalibrated medical sensors where thermal drift dominates total error budget.
