The MCP6566/6R/7/9 is a low-power, single-supply, open-drain output comparator from Microchip. It features low quiescent current, greater than rail-to-rail input range, open-drain output, wide voltage supply range, and can be used in single, dual, and quad configurations.
The MCP6566/6R/7/9 family from Microchip provides low‑power, single‑supply comparators with open‑drain outputs. They operate from 1.8 V to 5.5 V and are offered in single, dual and quad configurations with SC70, SOT‑23‑5, SOIC, MSOP and TSSOP packages.
The document lists electrical and AC characteristics, typical performance curves, temperature specifications, and recommended test circuits. It also includes design‑aid references such as the Microchip Advanced Part Selector and application notes.
| Supply Voltage Range | 1.8 V – 5.5 V |
|---|---|
| Quiescent Current (typical) | 100 µA per comparator |
| Input Offset Voltage (typical) | +3 mV |
| Propagation Delay (typical, high‑to‑low) | 56 ns at 1.8 V |
| Maximum Toggle Frequency | 4 MHz (typical) |
It operates from 1.8 V up to 5.5 V.
The typical high‑to‑low propagation delay is 56 ns at 1.8 V.
Each comparator draws about 100 µA of quiescent current (typical).
The typical input offset voltage is +3 mV.
