Product details
Overview
TSV611AILT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage sensor signal conditioning. It delivers 120 kHz gain bandwidth, 10 µA supply current at 5 V, and 800 µV max input offset voltage (A-grade), operating from 1.5 to 5.5 V - ideal for battery-powered smoke detectors and portable medical sensors.
For engineers reviewing the TSV611AILT datasheet, TSV611AILT pinout, TSV611AILT application, or TSV611AILT equivalent, key selection criteria include rail-to-rail I/O swing under 1.8 V supply, guaranteed phase margin >60°, input bias current ≤1 pA, and SOT23-5 thermal resistance of 250 °C/W - all critical for precision, low-noise, space-constrained analog front-ends.
Technical Context
The TSV611AILT employs complementary PMOS/NMOS input differential pairs enabling true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its unity-gain-stable architecture supports stable operation with capacitive loads up to 100 pF in follower configuration.
DC performance is characterized across 1.8 V, 3.3 V, and 5 V supplies with full specification over −40 °C to +85 °C. Input offset voltage drift is tightly controlled at 2 µV/°C, and CMRR reaches 80 dB at 5 V, ensuring robustness against supply and common-mode variations in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V logic without LDO overhead |
| Supply Current | 10.5 µA typ at 5 V - extends battery life beyond 10 years in 10 µA-sleep-cycle sensor nodes |
| Gain Bandwidth | 120 kHz typ - sufficient for DC–10 kHz sensor signal amplification (e.g., thermopile, piezoresistive) |
| Input Offset Voltage | 800 µV max (A-grade) - ensures <0.1% error in 0.8 V full-scale medical transducer outputs |
| Input Bias Current | 1 pA typ - prevents leakage-induced drift in high-impedance pH or photodiode interfaces |
| Output Swing | Within 35 mV of rails @ 10 kΩ load - preserves dynamic range in 1.8 V ADC reference designs |
| Phase Margin | 62° min at 5 V - guarantees stability in unity-gain buffer and active filter configurations |
Pinout & Package
SOT23-5 package: 5-pin ultra-small surface-mount outline (2.9 × 1.3 × 1.05 mm), RoHS-compliant, ECOPACK®2 rated, thermal resistance RthJA = 250 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; drives 10 kΩ load with <35 mV headroom to each rail |
| 2 (IN−) | Inverting input | High-impedance node (1 pA bias); accepts signals from VCC− −0.1 V to VCC+ +0.1 V |
| 3 (IN+) | Non-inverting input | Matches IN− in bias and CMR; enables precision instrumentation amplifier topologies |
| 4 (VCC−) | Negative supply / ground | Reference for single-supply operation; must be decoupled with 10 nF capacitor |
| 5 (VCC+) | Positive supply | Accepts 1.5–5.5 V; supports direct connection to regulated battery or LDO output |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8 V supply range - no lost headroom in low-voltage data acquisition |
| Ultra-low 10 µA supply current | Reduces quiescent power to 18 µW at 1.8 V - critical for multi-year battery life in wireless sensors |
| 1 pA typical input bias current | Eliminates significant error in >100 MΩ source impedances (e.g., electrochemical sensors) |
| 800 µV max input offset (A-grade) | Guarantees initial accuracy without factory trimming - lowers BOM cost in high-volume consumer devices |
| Stable with 100 pF capacitive load | Permits direct driving of ADC input capacitance or long PCB traces without external compensation |
Applications
| Smoke Detector Signal Chain | Portable ECG Front-End |
|---|---|
|
Use Scenario: Amplifying weak ionization chamber current (pA–nA) into measurable voltage for microcontroller ADC sampling. IC Role / Device Role / Timing Role: Low-noise, low-drift transimpedance amplifier stage with rail-to-rail output compatible with 1.8 V SAR ADC reference. Use Value: 1 pA input bias avoids signal corruption; 800 µV offset ensures <0.05% baseline error in smoke threshold detection. |
Use Scenario: Buffering and filtering biopotential signals from dry electrodes before 12-bit ADC digitization. IC Role / Device Role / Timing Role: Unity-gain rail-to-rail buffer isolating electrode impedance from ADC input while preserving DC-coupled baseline. Use Value: 10 µA supply current enables continuous monitoring on coin cell; 120 kHz GBW supports 100 Hz ECG bandwidth with margin. |
| Proximity Sensor Interface | Industrial Temperature Transmitter |
|
Use Scenario: Conditioning output of capacitive proximity sensor ICs (e.g., STM32TSC) in handheld tools. IC Role / Device Role / Timing Role: Active low-pass filter (2nd-order Sallen-Key) with precise cutoff set by A-grade offset and stable phase margin. Use Value: 2 µV/°C offset drift minimizes temperature-induced false triggers; 62° phase margin prevents peaking at filter cutoff. |
Use Scenario: Amplifying RTD or thermistor bridge output in 4–20 mA loop-powered field transmitters. IC Role / Device Role / Timing Role: Precision instrumentation amplifier input stage operating from 3.3 V derived from loop supply. Use Value: 80 dB CMRR at 5 V rejects common-mode noise from industrial 24 V DC lines; rail-to-rail I/O maximizes signal swing into ADC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-I/OT | Higher 100 kHz GBW; 6 µA supply current; no A-grade offset spec (max 2.5 mV) | Lower power but less DC precision; suitable for non-critical signal buffering | Select when offset drift and CMRR are secondary to ultra-low current (<6 µA) |
| TLV9001IDBVR | Higher 1 MHz GBW; 50 µA supply current; 0.25 mV max offset; wider temp range (−40 to 125 °C) | Better speed and precision, but 5× higher current - unsuitable for multi-year battery use | Select only if system requires >100 kHz bandwidth and can tolerate higher quiescent power |
Compared with MCP6001T-I/OT and TLV9001IDBVR, the TSV611AILT uniquely balances sub-10 µA current, A-grade 800 µV offset, and guaranteed rail-to-rail operation down to 1.5 V - making it optimal for precision, long-life, single-supply sensor nodes where power and DC accuracy are co-constrained.

FAQ
What is the maximum capacitive load the TSV611AILT can drive without external compensation?
The TSV611AILT is specified stable with up to 100 pF capacitive load in unity-gain buffer configuration, per datasheet Figure 19 and Section 3.4. Driving larger loads requires an in-series resistor (e.g., 10–100 Ω) between output and load, with final stability verified via bench testing and simulation using ST's macromodel.
Does the TSV611AILT support true rail-to-rail input at 1.5 V supply?
Yes - the input common-mode range extends from (VCC−) −0.1 V to (VCC+) +0.1 V across the full 1.5–5.5 V supply range, confirmed in Table 2 and Section 3.2. At 1.5 V, this provides −0.1 V to +1.6 V input range, enabling direct interface with sensors referenced to ground or VCC.
How does the A-grade (TSV611A) differ from standard TSV611 in production test?
The A-grade undergoes enhanced screening to guarantee input offset voltage ≤800 µV (vs. ≤2 mV for standard grade) and tighter offset drift (2 µV/°C typ). This is achieved through post-package trim and binning - not circuit topology change - and is documented in Tables 3–5 under "TSV61xA" rows.
Can the TSV611AILT operate from a single 1.5 V alkaline cell throughout its discharge curve?
Yes - the device operates down to 1.5 V (absolute minimum per Table 1), and key parameters including GBP (100 kHz min), CMRR (55 dB min), and supply current (6.5 µA min) remain fully specified at 1.5 V, enabling uninterrupted function from fresh cell (1.6 V) to end-of-life (~1.0 V with margin).
