GENERAL DESCRIPTION

The ADCMP603 is a very fast comparator fabricated on XFCB2, an Analog Devices, Inc., proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from VEE − 0.5 V to VCC + 0.2 V, low noise complementary TTL-/CMOS-compatible output drivers, latch inputs with adjustable hysteresis and a shutdown input. The device offers 3.5 ns propagation delay with 10 mV overdrive on 4 mA typical supply current.
