Product details
Overview
TSV6192ID 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 450 kHz gain bandwidth, 10 µA supply current at 5 V, 1.5–5.5 V operation, and 800 µV max input offset voltage (A-grade), enabling precision amplification in battery-powered smoke detectors and portable medical instrumentation.
For engineers reviewing the TSV6192ID datasheet, TSV6192ID pinout, TSV6192ID application, or TSV6192ID equivalent, key selection criteria include guaranteed stability at minimum gain ≥5 V/V, rail-to-rail output swing within 35 mV of both rails under 10 kΩ load, ultra-low 1 pA input bias current, and -40 to 85 °C industrial temperature range compliance.
Technical Context
The TSV6192ID employs complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its internal compensation ensures stability only when configured with closed-loop gain ≥5 V/V, verified by 60° phase margin at 10 kΩ/20 pF load.
Output stage design supports rail-to-rail swing-VOH ≤ 50 mV below VCC and VOL ≤ 50 mV above VCC− at 10 kΩ load-while maintaining 42–63 mA output drive capability across 1.5–5.5 V supply. Input offset drift is tightly controlled at 2 µV/°C, critical for DC-coupled sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 to 5.5 V - enables direct integration with single-cell Li-ion, alkaline, or coin-cell power sources without regulation. |
| Supply Current | 10.5 µA typ at 5 V - extends battery life beyond 10 years in 10 µA-sleep-cycle smoke detectors. |
| Gain Bandwidth Product | 450 kHz typ - supports anti-aliasing filtering and sensor signal amplification up to ~70 kHz with unity-gain stability margin. |
| Input Offset Voltage | 800 µV max (A-grade) - limits DC error to <0.02% FS in 4–20 mA transmitter circuits with 40 mV full-scale sensor output. |
| Input Bias Current | 1 pA typ - prevents leakage-induced errors in high-impedance pH or photodiode sensor interfaces (>1 GΩ source impedance). |
| CMRR | 80 dB min at 5 V - rejects common-mode noise from shared PCB ground planes in multi-channel portable ECG front-ends. |
| Output Drive | 52 mA sink / 58 mA source at 5 V - directly drives 10 kΩ active filters or ADC reference buffers without external gain staging. |
Pinout & Package
TSV6192ID is housed in an 8-pin MiniSO8 (3.0 × 4.9 mm) package with exposed pad for thermal enhancement and RoHS-compliant ECOPACK® construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Channel 1 output | Delivers rail-to-rail voltage swing; requires 10 nF local decoupling to VCC− for stability. |
| 2 (In1−) | Channel 1 inverting input | High-impedance node; sensitive to layout parasitics-must avoid routing near digital traces. |
| 3 (In1+) | Channel 1 non-inverting input | Accepts common-mode signals from VCC− −0.1 V to VCC+ +0.1 V; enables single-supply transducer interfacing. |
| 4 (VCC−) | Negative supply / ground | Reference for both channels; connects to system ground plane with low-inductance path. |
| 5 (VCC+) | Positive supply | Accepts 1.5–5.5 V; must be decoupled with 10 nF capacitor placed ≤2 mm from pin. |
| 6 (In2−) | Channel 2 inverting input | Electrically isolated from In1−; supports independent differential sensing on same die. |
| 7 (In2+) | Channel 2 non-inverting input | Matches In1+ specs; allows dual-sensor synchronous acquisition (e.g., temperature + humidity). |
| 8 (Out2) | Channel 2 output | Independent rail-to-rail output; shares VCC+/VCC− rails but has separate small-signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 0.1 V beyond supply rails; output swings within 35 mV of VCC+ and VCC− at 10 kΩ load-enables true single-supply 0–5 V signal chain design. |
| Ultra-low input bias current | 1 pA typical-preserves signal integrity in >100 MΩ source impedance applications like electrochemical gas sensors and piezoelectric vibration monitors. |
| Stable at minimum gain ≥5 V/V | Guaranteed 60° phase margin with 10 kΩ feedback and 20 pF capacitive load-eliminates need for external compensation in standard inverting/non-inverting configurations. |
| Low-voltage operation | Full specification down to 1.5 V supply-supports direct connection to aging alkaline cells (1.5 V nominal) without brown-out risk in portable pulse oximeters. |
| Industrial temperature range | -40 to 85 °C operating range-qualified for deployment in uncontrolled environments such as HVAC duct-mounted air quality sensors and outdoor smoke alarm housings. |
Applications
| Smoke Detector Signal Amplifier | Portable ECG Front-End |
|---|---|
|
Use Scenario: Amplifies weak ionization chamber current (pA–nA) into measurable voltage for microcontroller ADC sampling.

IC Role / Device Role / Timing Role: First-stage instrumentation amplifier driver with rail-to-rail output feeding 12-bit SAR ADC reference buffer. Use Value: 800 µV max input offset ensures <1 µV baseline error after calibration-critical for detecting sub-millivolt ST-segment deviations. |
| Proximity Sensor Interface | Medical Pulse Oximeter Analog Front-End |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher 170 µA supply current; 1 MHz GBW; no guaranteed min-gain stability requirement. | Better for higher-speed active filters but unsuitable for 10-year battery life targets. | Select only if bandwidth >450 kHz is required and power budget allows 17× higher quiescent current. |
| LMV358IDR | Wider 2.7–5.5 V supply range; 80 µA supply current; rail-to-rail output only (not input). | Limited to mid-supply common-mode inputs-requires level-shifting for 0 V-referenced sensors. | Choose when input common-mode range beyond VCC− is unnecessary and cost is primary constraint. |
Compared with MCP6022-E/SN and LMV358IDR, TSV6192ID uniquely combines 10 µA quiescent current, rail-to-rail input *and* output, and guaranteed stability at gain ≥5 V/V-making it the sole option for long-life, single-supply, high-impedance sensor nodes where space and power are co-constrained.

FAQ
Can TSV6192ID operate stably at unity gain?
No. The TSV6192ID is internally compensated for minimum closed-loop gain of 5 V/V (non-inverting) or -3 V/V (inverting). Attempting unity-gain configuration causes peaking and potential oscillation due to insufficient phase margin. Designers must use gain ≥5 V/V or add external compensation per Section 3.5 of the datasheet.
What is the maximum capacitive load the TSV6192ID can drive without instability?
The TSV6192ID remains stable with up to 20 pF capacitive load when using 10 kΩ feedback resistors and operating at 25 °C. Driving larger capacitive loads (e.g., ADC input capacitance >20 pF) requires isolation via a series resistor (≥100 Ω) between amplifier output and load to maintain 60° phase margin.
Does TSV6192ID support true split-supply operation (e.g., ±2.5 V)?
No. The TSV6192ID is specified only for single-supply operation from 1.5 V to 5.5 V referenced to VCC− (ground). Its absolute maximum rating allows only 6 V total supply difference; applying ±2.5 V would exceed VCC− rating limits and damage the device. Use dual-supply op-amps like TS912 for true bipolar operation.
How does the rail-to-rail input stage affect common-mode rejection at supply rails?
At input voltages within 0.7 V of either rail, the complementary PMOS/NMOS input pair transitions cause temporary degradation in CMRR (down to 53 dB) and input offset voltage (up to 1.4 mV). This is documented in Figures 13–14. For highest precision, keep Vicm ≥0.7 V away from VCC+ and VCC−, or calibrate out offset in firmware.
