MCP6561/1R/1U/2/4 1.8V Low-Power Push-Pull Output Comparator Features Description
• Propagation Delay at 1.8VDD: The Microchip Technology, Inc. MCP6561/1R/1U/2/4 - 56 ns (typical) High-to-Low families of CMOS/TTL compatible comparators are - 49 ns (typical) Low-to-High offered in single, dual, and quad configurations. • Low Quiescent Current: 100 µA (typical) These comparators are optimized for low power 1.8V, • Input Offset Voltage: ±3 mV (typical) single-supply applications with greater than rail-to-rail input operation. The internal input hysteresis eliminates • Rail-to-Rail Input: VSS - 0.3V to VDD + 0.3V output switching due to internal input noise voltage, • CMOS/TTL-Compatible Output reducing current draw. The push-pull output of the • Wide Supply Voltage Range: 1.8V to 5.5V MCP6561/1R/1U/2/4 family supports rail-to-rail output • Available in Single, Dual, and Quad swing, and interfaces with CMOS/TTL logic. The output • Packages: SC70-5, SOT-23-5, SOIC, MSOP, toggle frequency can reach a typical of 4 MHz (typical) TSSOP while limiting supply current surges and dynamic power consumption during switching.
