Product details
Overview
TSV6192AIST 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, 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and operates from 1.5 to 5.5 V - enabling use in battery-powered smoke detectors and portable medical instrumentation.
For engineers reviewing the TSV6192AIST datasheet, TSV6192AIST pinout, TSV6192AIST application, or TSV6192AIST equivalent, key selection criteria include guaranteed stability at gain ≥4, rail-to-rail output swing within 35 mV of rails under 10 kΩ load, -40 to 85 °C industrial temperature range, and MiniSO8 packaging for space-constrained PCB layouts.
Technical Context
The TSV6192AIST 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 ≥4 (non-inverting) or ≤−3 (inverting), verified via 60° phase margin at 450 kHz GBP with 20 pF load.
Output stage design enables rail-to-rail swing: VOH ≤50 mV below VCC and VOL ≤50 mV above VCC− at 10 kΩ load, while maintaining 49 mA sourcing and 42 mA sinking capability at 5 V supply - critical for driving ADC reference buffers and transducer interface circuits directly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 to 5.5 V - supports single-cell Li-ion, two-cell alkaline, and 3.3 V/5 V system rails without level shifting. |
| Gain Bandwidth Product | 450 kHz typ - sufficient for DC–100 Hz sensor signals with >10× gain margin before phase rolloff. |
| Input Offset Voltage | 800 µV max (A version) - enables <1% error in 100 mV full-scale bridge sensor outputs without trimming. |
| Supply Current per Amp | 10.5 µA typ at 5 V - allows 10-year operation on CR2032 coin cell in always-on proximity sensing nodes. |
| Input Bias Current | 1 pA typ - preserves high-impedance pH electrode and piezoelectric sensor signal integrity. |
| Common-Mode Rejection | 80 dB min at 5 V - rejects power rail noise in single-supply front-end amplifiers driving SAR ADCs. |
| Output Drive | ±49 mA at 5 V - directly drives 10 kΩ loads (e.g., ADC input RC filters) without external buffers. |
Pinout & Package
TSV6192AIST is housed in a MiniSO8 (3.0 × 4.9 mm) thermally enhanced package with exposed pad for improved heat dissipation in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Amplifier 1 output | Delivers rail-to-rail voltage swing; requires local 10 nF decoupling to VCC− for stability. |
| 2 (In1−) | Amplifier 1 inverting input | High-impedance node (1 pA bias); sensitive to leakage - avoid conformal coating over trace. |
| 3 (In1+) | Amplifier 1 non-inverting input | Accepts signals from VCC− −0.1 V to VCC+ +0.1 V; enables direct connection to resistive divider references. |
| 4 (VCC−) | Negative supply / ground | Return path for both amplifiers; must be low-impedance with dedicated plane or wide trace. |
| 5 (In2+) | Amplifier 2 non-inverting input | Independent high-Z input; usable for differential pair configuration with In1+ as common-mode reference. |
| 6 (In2−) | Amplifier 2 inverting input | Matches In1− specs; supports dual-channel instrumentation amp topology with shared gain resistor. |
| 7 (Out2) | Amplifier 2 output | Electrically isolated from Out1; allows independent filtering or level-shifting per channel. |
| 8 (VCC+) | Positive supply | Accepts 1.5–5.5 V; requires 10 nF ceramic capacitor placed ≤2 mm from pin per ST layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems - no lost headroom at input or output. |
| Ultra-low input bias current | 1 pA typ preserves signal integrity in >1 GΩ source impedance applications like electret mic preamps. |
| Guaranteed stability at gain ≥4 | Eliminates need for external compensation components in standard non-inverting configurations. |
| Low input offset drift | 2 µV/°C max ensures <20 µV total offset shift across −40 to 85 °C - critical for uncalibrated medical sensors. |
| MiniSO8 thermal performance | RthJA = 190 °C/W enables 100 µW dissipation at <10 °C rise - suitable for sealed enclosure deployments. |
Applications
| Smoke Detector Signal Chain | Portable ECG Front-End |
|---|---|
|
Use Scenario: Amplifying weak ionization chamber current (pA–nA) in battery-powered residential smoke alarms. IC Role / Device Role / Timing Role: First-stage transimpedance amplifier converting chamber current to voltage with minimal input loading. Use Value: 1 pA input bias current prevents signal loss; 10 µA quiescent current extends CR123A battery life to >5 years in standby mode. |
Use Scenario: Conditioning low-amplitude (0.5–2 mV), low-frequency (<100 Hz) biopotential signals from dry electrodes. IC Role / Device Role / Timing Role: Dual-channel instrumentation amplifier core providing gain and common-mode rejection before 24-bit delta-sigma ADC. Use Value: 800 µV max Vos avoids baseline drift in 100× gain stage; rail-to-rail output drives ADC reference without clipping. |
| Proximity Sensor Interface | Active Low-Pass Filter for IoT Node |
|
Use Scenario: Amplifying capacitance-change signals from self-capacitive touch panels in smart home controllers. IC Role / Device Role / Timing Role: Charge amplifier converting ∆C to voltage, followed by buffer driving 100 kΩ ADC input. Use Value: 1.5 V minimum supply enables direct connection to energy-harvesting PMIC outputs; 450 kHz GBP supports 10 kHz sampling with anti-aliasing. |
Use Scenario: Implementing 2nd-order Sallen-Key low-pass filter (fc = 10 Hz) in battery-operated environmental sensor nodes. IC Role / Device Role / Timing Role: Dual op-amp implementing unity-gain buffer + filter stage with matched DC performance. Use Value: Dual topology reduces component count vs. discrete amps; 10 µA per channel cuts filter power to <21 µW at 3.3 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6192IDT | Same die, SO8 package (RthJA = 125 °C/W), 2 mV max Vos (non-A grade) | Higher thermal performance but larger footprint; suitable for board-level calibration where offset trim is acceptable. | Select when PCB area permits SO8 and production cost favors standard SOIC reflow profile. |
| MCP6022-E/SN | 2.7–5.5 V supply only; 100 µA ICC; 3 MHz GBP; 3 mV Vos | Higher speed and drive, but 10× higher current - unsuitable for multi-year battery life requirements. | Choose only if system demands >100 kHz signal bandwidth and can tolerate reduced runtime. |
Compared with TSV6192IDT, TSV6192AIST trades 65 °C/W higher thermal resistance for 30% smaller area and guaranteed 800 µV Vos; versus MCP6022-E/SN, it delivers 10× lower quiescent current at the cost of bandwidth - making it optimal for sub-100 Hz, long-life sensor nodes.

FAQ
What is the minimum stable gain configuration for TSV6192AIST?
The TSV6192AIST requires a closed-loop gain of ≥4 in non-inverting mode or ≤−3 in inverting mode to ensure 60° phase margin and prevent oscillation. This is due to internal compensation optimized for low-power operation; using unity-gain configurations will cause instability and overshoot in step response.
Can TSV6192AIST operate from a 1.5 V supply?
Yes - the device is fully specified from 1.5 V to 5.5 V. At 1.5 V, it maintains 380 kHz gain bandwidth, 10 µA supply current, and rail-to-rail output swing within 50 mV of both rails into 10 kΩ, enabling compatibility with single alkaline or NiMH cells without voltage boosting.
Does TSV6192AIST require external decoupling capacitors?
Yes - ST recommends placing a 10 nF ceramic capacitor between pins 4 (VCC−) and 8 (VCC+) as close as possible to the package (≤2 mm trace length). This is mandatory to suppress high-frequency supply noise and maintain stability, especially in gain ≥4 configurations with capacitive loads.
How does the A-grade (TSV6192AIST) differ from standard TSV6192IST?
The "A" suffix denotes tighter input offset voltage specification: 800 µV max versus 2 mV max for the standard grade. All other parameters - supply current, GBP, input bias, and thermal characteristics - are identical. The A-grade is selected for precision DC-coupled applications like medical sensor front-ends where offset drift must be minimized.
