GENERAL DESCRIPTION
The ADCMP604 and ADCMP605 are very fast comparators
fabricated on Analog Devices, Inc.’s, proprietary XFCB2
process. This family of comparators is exceptionally versatile
and easy to use. Features include an input range from VEE − 0.5
V to VCC + 0.2 V, low noise, LVDS-compatible output drivers,
and TTL/CMOS latch inputs with adjustable hysteresis and/or
shutdown inputs.
The devices offer 1.5 ns propagation delays with 1 ps rms
random jitter (RJ). Overdrive and slew rate dispersion are
typically less than 50 ps.
A flexible power supply scheme allows the devices to operate
with a single +2.5 V positive supply and a −0.5 V to +3.0 V
input signal range up to a +5.5 V positive supply with a −0.5 V

to +6 V input signal range. Split input/output supplies, with no
sequencing restrictions on the ADCMP605, support a wide
input signal range with greatly reduced power consumption.
The LVDS-compatible output stage is designed to drive any
standard LVDS input. The comparator input stage offers robust
protection against large input overdrive, and the outputs do not
phase reverse when the valid input signal range is exceeded.
High speed latch and programmable hysteresis features are also
provided in a unique single-pin control option.
The ADCMP604 is available in a 6-lead SC70 package. The
ADCMP605 is available in a 12-lead LFCSP.
