Product details
Overview
TSV6192IDT 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, and operates from 1.5 V to 5.5 V supply - enabling use in battery-powered smoke detectors and portable medical instrumentation.
For engineers reviewing the TSV6192IDT datasheet, TSV6192IDT pinout, TSV6192IDT application, or TSV6192IDT equivalent, key selection criteria include guaranteed stability at minimum gain ≥5 V/V, rail-to-rail output swing within 35 mV of rails under 10 kΩ load, and 1 pA typical input bias current for high-impedance transducer interfacing.
Technical Context
The TSV6192IDT employs complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (≤35 mV from either rail with 10 kΩ load). Its internal compensation ensures stability only when configured for closed-loop gain ≥5 V/V (non-inverting) or ≥−3 V/V (inverting).
It features 800 µV maximum input offset voltage (A-grade), 2 µV/°C offset drift, and 76–93 dB supply voltage rejection ratio across 1.8–5 V supplies - making it suitable for precision DC-coupled amplification in thermistor or photodiode front-ends where supply variation and temperature drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - supports single-cell Li-ion, alkaline, or coin-cell operation without level-shifting. |
| Quiescent Current | 10.5 µA typ at 5 V - enables >10-year battery life in always-on smoke detector sensors. |
| Gain Bandwidth Product | 450 kHz typ - sufficient for anti-aliasing filters and low-frequency sensor signal conditioning up to ~40 kHz. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like pH electrodes or piezoresistive sensors. |
| Output Swing | Within 35 mV of VCC and GND with 10 kΩ load - maximizes dynamic range in 3.3 V or lower ADC systems. |
| Input Offset Voltage | 800 µV max (A version) - reduces DC error in precision bridge amplifier configurations. |
| Stable Gain Configuration | ≥5 V/V non-inverting or ≥−3 V/V inverting - mandates external resistor selection to avoid oscillation. |
Pinout & Package
TSV6192IDT is housed in an 8-pin MiniSO8 (SO-8 compatible) package with exposed pad for thermal enhancement and RoHS-compliant ECOPACK® construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts differential input signal referenced to non-inverting input; high-impedance node requiring guard trace in sensitive layouts. |
| 2 | Non-inverting Input (Channel 1) | Primary reference node for Channel 1; rail-to-rail common-mode range enables direct connection to resistive divider outputs. |
| 3 | Output (Channel 1) | Delivers rail-to-rail buffered signal; capable of sourcing 58 mA and sinking 52 mA at 5 V supply. |
| 4 | VCC− (Ground) | Power return path; must be connected to low-impedance ground plane with local 10 nF decoupling capacitor. |
| 5 | VCC+ (Supply) | Positive supply input; requires dedicated 10 nF ceramic capacitor placed ≤2 mm from pin per layout guidelines. |
| 6 | Non-inverting Input (Channel 2) | Independent input for second channel; electrically isolated from Channel 1 except via shared supply rails. |
| 7 | Inverting Input (Channel 2) | Second differential input pair; identical electrical specs to Pin 1 but separate physical terminal. |
| 8 | Output (Channel 2) | Second independent output; supports dual-sensor readout or differential driver configuration without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization across 1.5–5.5 V supplies - critical for maximizing SNR in low-voltage data acquisition. |
| Ultra-low input bias current (1 pA typ) | Minimizes voltage error in high-Z sensor interfaces (e.g., glass electrode pH probes) without requiring guard rings or active guarding. |
| Guaranteed stability at gain ≥5 V/V | Eliminates need for external compensation components in standard non-inverting amplifier designs - reducing BOM count and board area. |
| −40 °C to +85 °C operating range | Validated performance over industrial temperature range - suitable for automotive cabin sensors and outdoor environmental monitors. |
| Low THD+N (0.1 % at 1 kHz) | Maintains signal fidelity in active filtering and audio pre-amplifier stages where harmonic distortion impacts measurement accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6192IST | Same silicon die, MiniSO8 package with smaller footprint (3.0 × 4.9 mm vs SO8's 4.9 × 6.0 mm) and lower thermal resistance (190 °C/W vs 125 °C/W). | Better suited for space-constrained portable devices where PCB area is premium and thermal dissipation is limited. | Select TSV6192IST for compact wearables; choose TSV6192IDT for legacy SO8 footprints or higher power handling margin. |
| MCP6022-E/SN | Higher supply current (100 µA), wider supply range (2.7–5.5 V), no rail-to-rail input - input common-mode limited to VCC− to VCC− +0.3 V. | Not suitable for sub-2 V operation or sensors requiring input swing to ground; acceptable for 3.3 V systems with mid-supply biased inputs. | Use MCP6022-E/SN only if design already uses Microchip ecosystem and can accommodate higher current draw and restricted input range. |
Compared with TSV6192IST, the TSV6192IDT offers superior thermal performance in standard SO8 layout but occupies more board area; versus MCP6022-E/SN, it enables true 1.5 V operation and rail-to-rail input - essential for modern ultra-low-power sensor nodes where every µA and millivolt matters.

FAQ
What is the minimum recommended gain for stable operation of the TSV6192IDT?
The TSV6192IDT requires a closed-loop gain of at least 5 V/V in non-inverting configuration or −3 V/V in inverting configuration to ensure phase margin ≥60° and prevent oscillation. This is due to internal compensation optimized for unity-gain unstable operation - using lower gains risks instability and peaking in frequency response.
Can the TSV6192IDT operate from a 1.5 V supply?
Yes, the TSV6192IDT is fully specified and guaranteed to operate from 1.5 V to 5.5 V. Electrical characteristics including 450 kHz gain bandwidth, 10 µA supply current, and rail-to-rail input/output functionality are validated down to 1.5 V, making it suitable for single alkaline or zinc-carbon cell applications.
Does the TSV6192IDT have phase reversal protection?
Yes, the TSV6192IDT is explicitly guaranteed against phase reversal across its entire input common-mode range (VCC− −0.1 V to VCC+ +0.1 V). This eliminates risk of output latch-up or erroneous logic-level transitions when input signals exceed supply rails - critical in sensor interfaces with transient overvoltage conditions.
What decoupling capacitance is required for stable operation?
A 10 nF ceramic capacitor must be placed as close as possible (≤2 mm) to both VCC+ (Pin 5) and VCC− (Pin 4) pins, with short, low-inductance traces to the ground plane. This is mandated in the datasheet to suppress high-frequency supply noise and prevent oscillation caused by parasitic inductance in power routing.
