MCP6569

MCP6566/6R/6U/7/9 1.8V Low-Power Open-Drain Output Comparator Features Propagation Delay at 1.8 VDD: - 56 ns (typical) high-to-low Low Quiescent Current: 100 µA (typical) Input Offset Voltage: ±3 mV (typical) Rail-to-Rail Input: VSS – 0.3V to VDD + 0.3V Open-Drain Output Wide Supply Voltage Range: 1.8V to 5.5V Available in Single, Dual and Quad Packages: SC70, SOT-23, SOIC, MSOP, TSSOP Typical Applications Laptop Computers Mobile Phones Handheld Electronics RC Timers Alarm and Monitoring Circuits Window Comparators Multivibrators Design Aids Microchip Advanced Part Selector (MAPS) Analog Demonstration and Evaluation Boards Application Notes SPICE Macro Model Related Device Push-Pull Output: MCP6561/1R/1U/2/4 Typical Application Circuit VIN VDD R2 +3 VPU +5 VDD – MCP656X + VOUT R3 RF Description The Microchip MCP6566/6R/6U/7/9 family of opendrain output comparators is offered in single, dual and quad configurations. These comparators are optimized for low-power 1.8V, single-supply applications with greater than rail-to-rail input operation. The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The open-drain output of the MCP6566/6R/6U/7/9 family requires a pull-up resistor. It supports pull-up voltages that are above and below VDD, which can be used to level shift. The output toggle frequency can reach a typical 4 MHz (typical) while limiting supply current surges ...
