Product details
Overview
TSV6192AIDT 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 TSV6192AIDT datasheet, TSV6192AIDT pinout, TSV6192AIDT application, or TSV6192AIDT equivalent, key selection criteria include guaranteed stability at gain ≥4, rail-to-rail swing within 35 mV of rails under 10 kΩ load, -40 to 85 °C operation, and MiniSO8/SO8 package compatibility for space-constrained analog front-ends.
Technical Context
The TSV6192AIDT 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), as verified by 60° phase margin at 450 kHz GBP with 20 pF load.
Output stage design enables rail-to-rail sourcing/sinking up to 58 mA (Isource) and 52 mA (Isink) at 5 V, while maintaining <35 mV saturation voltage to either rail under 10 kΩ load to VCC/2 - critical for precision single-supply signal buffering and active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 to 5.5 V - supports direct integration with Li-ion, coin-cell, and 3.3 V logic systems without level-shifting. |
| Gain Bandwidth Product | 450 kHz typ - enables stable amplification of DC–100 kHz sensor signals (e.g., thermistor, piezoelectric) with unity-gain-stable margin. |
| Input Offset Voltage (A-grade) | ≤800 µV max - ensures ≤0.8 mV error in 1 V full-scale sensor output, critical for 12-bit ADC interfacing. |
| Supply Current per Amplifier | 10.5 µA typ at 5 V - allows >1-year operation on 220 mAh coin cell in always-on proximity sensing nodes. |
| Input Bias Current | 1 pA typ - eliminates leakage-induced errors in high-impedance pH or photodiode transimpedance circuits. |
| Common-Mode Rejection Ratio | 80 dB typ at 5 V - rejects power-supply ripple and EMI coupling in noisy industrial sensor environments. |
| Slew Rate | 0.08 V/µs - sufficient for settling 1 V step in <15 µs, meeting response requirements for smoke detector alarm thresholds. |
Pinout & Package
TSV6192AIDT is housed in an SO-8 (Small Outline) package compliant with ECOPACK® environmental standards, measuring 4.9 mm × 6.0 mm × 1.75 mm (max height), with 1.27 mm lead pitch and gull-wing leads for standard reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Amplifier 1 output | Delivers rail-to-rail voltage swing; must drive ≥10 kΩ load for specified VOL/VOH performance. |
| 2 (In1−) | Amplifier 1 inverting input | High-impedance node (1 pA bias); requires guard ring routing in PCB layout to minimize leakage. |
| 3 (In1+) | Amplifier 1 non-inverting input | Accepts common-mode voltages from VCC− −0.1 V to VCC+ +0.1 V - enables direct connection to resistive sensor dividers. |
| 4 (VCC−) | Negative supply / ground reference | Must be decoupled with 10 nF capacitor placed ≤2 mm from pin to suppress PSRR degradation above 10 kHz. |
| 5 (VCC+) | Positive supply | Accepts 1.5–5.5 V; supplies both amplifiers - shared rail simplifies single-supply system design. |
| 6 (In2+) | Amplifier 2 non-inverting input | Independent high-Z input; usable for differential pair configuration with In1+ or separate sensor channel. |
| 7 (In2−) | Amplifier 2 inverting input | Matches In1− specs; supports matched feedback networks for identical gain/offset across dual channels. |
| 8 (Out2) | Amplifier 2 output | Functionally identical to Out1; enables dual-path signal conditioning (e.g., sensor + reference channel). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 0.1 V beyond rails; output swings within 35 mV of VCC+/VCC− - eliminates need for dual supplies in portable devices. |
| Ultra-low input bias current | 1 pA typ enables accurate measurement of nanoamp-level currents from photodiodes or electrochemical sensors without external guarding. |
| Stable at minimum gain ≥4 | Guaranteed 60° phase margin at 450 kHz with 20 pF capacitive load - prevents oscillation in active filters using standard RC feedback. |
| A-grade precision | 800 µV max input offset voltage ensures <0.1% gain error in 1 V-range medical sensor amplifiers without trimming. |
| Extended temperature operation | Specified over −40 to 85 °C - supports deployment in automotive cabin modules and outdoor IoT edge nodes. |

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 |
|---|---|---|---|
| TSV6192IDT | Standard grade (5 mV max Vio vs. 0.8 mV for A-grade); otherwise identical electrical specs and pinout. | Acceptable for non-precision applications like basic battery monitoring where offset error <5 mV is tolerable. | Select TSV6192IDT only if cost sensitivity outweighs precision requirements - no PCB redesign needed. |
| MCP6022-E/SN | Higher supply current (100 µA vs. 10.5 µA); wider supply range (2.7–5.5 V); 1 MHz GBP; 3.5 mV max Vio. | Better for higher-speed active filters but unsuitable for multi-year battery life targets due to 10× higher quiescent current. | Choose MCP6022-E/SN only when bandwidth >450 kHz is mandatory and power budget allows ≥100 µA per amplifier. |
Compared with TSV6192IDT, the TSV6192AIDT provides 6.25× lower input offset for precision sensor interfaces, while MCP6022-E/SN trades 10× higher current for 2.2× higher bandwidth - making TSV6192AIDT optimal for ultra-low-power, sub-100 kHz analog front-ends where accuracy and longevity are prioritized.

FAQ
What is the minimum closed-loop gain required for stable operation of TSV6192AIDT?
The TSV6192AIDT requires a minimum non-inverting closed-loop gain of 4 or inverting gain of −3 to ensure stability, as confirmed by 60° phase margin testing with 20 pF capacitive load. Operating below this gain risks oscillation due to insufficient internal compensation margin, particularly above 100 kHz. This constraint is inherent to its 450 kHz GBP architecture and must be respected in all designs.
Can TSV6192AIDT operate from a 1.5 V supply, and what performance changes occur?
Yes, TSV6192AIDT is fully specified down to 1.5 V supply, with tested parameters including 380 kHz GBP, 10.5 µA supply current, and rail-to-rail output swing within 50 mV of rails under 10 kΩ load. Input common-mode range remains VCC− −0.1 V to VCC+ +0.1 V, and offset voltage stays ≤800 µV. Performance degrades only marginally versus 5 V operation, enabling true single-cell alkaline or lithium primary battery use.
How does the A-grade (TSV6192AIDT) differ electrically from the standard TSV6192IDT?
The A-grade designation guarantees maximum input offset voltage of 800 µV (vs. 5 mV for standard grade) and tighter input offset voltage drift (2 µV/°C vs. unspecified for standard). All other parameters - supply current, GBP, rail-to-rail behavior, and pinout - are identical. This makes TSV6192AIDT essential for applications demanding <0.1% gain accuracy without calibration, such as medical sensor front-ends.
What PCB layout practices are critical for achieving specified noise and PSRR performance?
Place 10 nF ceramic decoupling capacitors ≤2 mm from each VCC+ and VCC− pin, use solid ground planes beneath the device, route sensitive inputs (In+, In−) away from digital traces, and implement guard rings around high-impedance nodes. These practices reduce supply-induced noise coupling and maintain the specified 93 dB PSRR and 105 nV/√Hz input noise density at 5 V, as validated in ST's characterization data.
