Microchip | MCP6561T-E/OT

A Comparator circuit compares two voltage signals and and determines which one is greater. The result of this comparison is indicated by the output voltage.

Op-amps and comparators are similar but the not same. You can use an op amp for a comparator but not exactly vice-versa; comparators do not have the internal integrator that is key to an op amp.

The Microchip Technology, Inc. MCP6561/2/4 families of CMOS/TTL compatible comparators are 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 push-pull output of the MCP6561/2/4 family supports rail-to-rail output swing, and interfaces with CMOS/TTL logic. The output toggle frequency can reach a typical of 4 MHz (typical) while limiting supply current surges and dynamic power consumption during switching.

This family operates with single supply voltage of 1.8V to 5.5V while drawing less than 100 μA/comparator of quiescent current (typical).

Typical Applications:

• Laptop computers
• Mobile Phones
• Hand-held Electronics
• RC Timers
• Alarm and Monitoring Circuits
• Window Comparators
• Multi-vibrators

The MCP6561T-E/OT is available in a SOT-23 5-Lead package with a temperature range of -40C to +125C.
