Description

The Microchip Technology Inc. MCP6571/1R/1U/2/4

family of CMOS/TTL compatible comparators operate

with a single-supply voltage, as low as 1.8V, while

drawing low-quiescent current (70 μA, maximum per

comparator). This family of comparators incorporate a

Power-on-Reset feature that keeps the output high

impedance until the supply voltage VDD rises to a

sufficient voltage to control the comparator. They also

have a low-input offset voltage (±7 mV, maximum).

These comparators are optimized for low-power, single

supply applications with greater than rail-to-rail input

operation. Internal input hysteresis eliminates output

switching due to internal input noise voltage, reducing

current draw. These comparators are provided with

push-pull outputs.

This family is offered in single (MCP6571), dual

(MCP6572) and quad (MCP6574) packages. All

devices are designed using an advanced CMOS

process and fully specified in the extended temperature

range from -40°C to +125°C.
