GENERAL DESCRIPTION
The ADCMP604/ADCMP605 are very fast comparators
fabricated on the Analog Devices, Inc. proprietary XFCB2
process. These comparators are exceptionally versatile and easy
to use. Features include an input range from V
0.2 V, low noise, LVDS-compatible output drivers, and
TTL/CMOS latch inputs with adjustable hysteresis and/or shut-
down 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.

V
A flexible power supply scheme allows the devices to operate
with a single 2.5 V positive supply and a −0.5 V to +2.7 V input
signal range up to a 5.5 V positive supply with a −0.5 V to +5.7 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, and the
ADCMP605 is available in a 12-lead LFCSP.

... The ADCMP604/ADCMP605 dispersion is typically <1 the overdrive varies from 125 mV.

... ADCMP604/ADCMP605 The hysteresis control pin appears as a 1.25 V bias voltage seen through a series resistance of 70 kΩ ± 20% throughout the hysteresis control range. The advantages of applying hysteresis in this manner are improved accuracy, improved stability, reduced component count, and maximum versatility. An external bypass capacitor is not recommended on the HYS pin because it would likely degrade the jitter performance of the device and impair the latch function ...
