GENERAL DESCRIPTION
The ADCMP609 is a fast comparator fabricated on XFCB2, an Analog Devices, Inc. proprietary process. These comparators are exceptionally versatile and easy to use. Features include an input range from VEE − 0.2 V to VCC + 0.2 V, low noise, TTL-/CMOS-compatible output drivers, and adjustable hysteresis and/or shutdown inputs.

FEATURES
    Fully specified rail to rail at VCC = 2.5 V to 5.5 V
    Input common-mode voltage from −0.2 V to VCC + 0.2 V
    Low glitch CMOS-/TTL-compatible output stage
    40 ns propagation delay
    Low power 1 mW at 2.5 V
    Shutdown pin
