Product details
Overview
TSV612AIDT from STMicroelectronics is a dual 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 per channel at 5 V, and 800 µV max input offset voltage (A-grade), operating from 1.5 V to 5.5 V in industrial temperature range (−40 °C to +85 °C). It is used in battery-powered smoke detectors and proximity sensors where rail-to-rail swing and nanoampere-level bias current are critical.
For engineers reviewing the TSV612AIDT datasheet, TSV612AIDT pinout, TSV612AIDT application, or TSV612AIDT equivalent, key selection criteria include guaranteed A-grade offset voltage, 1 pA typical input bias current, unity-gain stability with capacitive loads up to 100 pF, and SO-8 package compatibility with legacy PCB layouts for dual op-amp replacements.
Technical Context
The TSV612AIDT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) without phase reversal. Its output stage drives within 35 mV of both rails under 10 kΩ load, supporting full-swing signal acquisition in single-supply systems.
It features unity-gain stable compensation optimized for micro-power operation, delivering 62° phase margin at 5 V and maintaining 120 kHz GBP across 1.5–5.5 V supply range. Input offset drift is tightly controlled at 2 µV/°C, and PSRR reaches 93 dB at 5 V - critical for noisy battery-fed environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V logic without LDOs |
| Supply Current per Channel | 10.5 µA typ at 5 V - supports >10-year battery life in always-on smoke detectors |
| Gain Bandwidth Product | 120 kHz typ - sufficient for DC–10 kHz sensor amplification (e.g., piezoelectric proximity sensing) |
| Input Offset Voltage (A-grade) | ≤800 µV max - ensures <0.1% error in 0.8 V full-scale medical transducer outputs |
| Input Bias Current | 1 pA typ - prevents leakage-induced error in high-Z pH or photodiode front-ends |
| CMRR | 80 dB min at 5 V - rejects supply ripple and EMI in unshielded portable enclosures |
| Slew Rate | 0.04 V/µs - adequate for <100 mV step response in active filtering without overshoot |
Pinout & Package
TSV612AIDT is housed in an 8-pin SO-8 (Small Outline) package with standard 1.27 mm pitch, RoHS-compliant, ECOPACK®-qualified, and rated for industrial temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback or signal inversion node; compatible with standard inverting amplifier configurations |
| 2 | Non-inverting input (Channel 1) | High-impedance sensor interface point; 1 pA bias current minimizes loading on resistive dividers |
| 3 | Output (Channel 1) | Drives ≤10 kΩ loads to within 35 mV of rails; stable with 100 pF capacitive loads in unity-gain buffer |
| 4 | VCC− (Ground) | Reference return for dual-supply or single-supply operation; decoupling capacitor required at pin |
| 5 | Non-inverting input (Channel 2) | Independent second channel input; identical specs enable dual-sensor synchronous readout |
| 6 | Inverting input (Channel 2) | Supports differential pair configuration with Channel 1 for noise-rejecting instrumentation topologies |
| 7 | Output (Channel 2) | Matches Channel 1 performance; allows independent gain staging or dual-channel filtering |
| 8 | VCC+ (Supply) | Accepts 1.5–5.5 V; internal regulation not required; 10 nF ceramic decoupling mandatory per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 0.1 V beyond rails; output swings to within 35 mV - enables full dynamic range utilization in 1.8 V systems |
| Ultra-low input bias current | 1 pA typical - eliminates guard-ring design requirements for >100 MΩ source impedances |
| A-grade precision | 800 µV max VIO - reduces calibration burden in factory-trimmed medical sensor modules |
| Unity-gain stable | No external compensation needed - simplifies active filter design and reduces BOM count |
| Low-noise operation | 105 nV/√Hz at 1 kHz - preserves SNR in low-amplitude thermopile or strain gauge signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV612IST | Same silicon, MiniSO-8 package (3.0 × 4.9 mm vs SO-8's 3.9 × 4.9 mm); 190 °C/W RthJA vs 125 °C/W | Preferred for space-constrained portable devices; thermal derating required above 3.3 V at full ambient | Select when board area is constrained and thermal margin permits; verify junction temp at max load |
| MCP6022-E/SN | Higher supply current (100 µA), wider GBW (1 MHz), no A-grade option; 2.7–5.5 V only | Better for higher-speed active filters but unsuitable for multi-year battery life targets | Choose only if bandwidth >100 kHz is mandatory and power budget allows 10× higher quiescent draw |
Compared with TSV612IST, TSV612AIDT offers superior thermal performance and drop-in compatibility with legacy SO-8 footprints; versus MCP6022-E/SN, it trades bandwidth for 10× lower power and guaranteed A-grade offset - making it optimal for energy-critical, precision DC–low-frequency sensing.

FAQ
What is the maximum capacitive load the TSV612AIDT can drive without external compensation?
The TSV612AIDT is unity-gain stable and can drive up to 100 pF capacitive load directly in buffer configuration without oscillation, as verified in Figure 19 of the official datasheet. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) between output and load is recommended to maintain phase margin above 60°.
Does the TSV612AIDT support true single-supply operation down to 1.5 V?
Yes - the TSV612AIDT operates fully specified from 1.5 V to 5.5 V, with rail-to-rail input extending 0.1 V beyond each supply rail and output swing within 35 mV of both rails under 10 kΩ load. Electrical characteristics including GBP (100 kHz min at 1.5 V) and VIO (≤2 mV) are guaranteed across this range.
How does the A-grade (TSV612AIDT) differ from standard TSV612IDT in production testing?
The 'A' suffix denotes enhanced screening: input offset voltage is binned to ≤800 µV max (vs ≤2 mV for standard grade) at 25 °C and across −40 °C to +85 °C, and input offset drift is characterized to ≤2 µV/°C. This enables reduced system calibration overhead in precision sensor applications without additional trimming circuitry.
Is the SO-8 package of TSV612AIDT lead-free and RoHS compliant?
Yes - the TSV612AIDT uses an ECOPACK®-qualified SO-8 package meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device carries the "ECOPACK2" designation, indicating halogen-free molding compound and lead-free terminations with matte tin plating, fully compliant with JEDEC J-STD-020 moisture sensitivity level 3.
