General Description

MCP6576/6R/6U/7/9 from Microchip Technology is a

family of CMOS/TTL compatible comparators that

operate with a single supply voltage, as low as 1.8V,

while drawing low quiescent current (70 μA, maximum

per amplifier). These comparators incorporate a POR

feature that keeps the output high impedance until VDD

rises to a sufficient voltage to control the comparator.

MCP6576/6R/6U/7/9 also has a low input offset voltage

(±7 mV, maximum).

The MCP6576/6R/6U/7/9 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, resulting in reduced current draw. The devices

are provided with open-drain outputs.

The family of comparators are offered in single

(MCP6576/6R/6U), dual (MCP6577), and quad

(MCP6579) packages.

All devices are designed using an advanced CMOS

process and fully specified in the extended temperature

range of -40°C to +125°C.
