GENERAL DESCRIPTION
The AD8465 is a very fast comparator fabricated on the Analog
Devices, Inc., proprietary XFCB2 process. This comparator is
exceptionally versatile and easy to use. Features include an
input range from VEE 0.5 V to VCCI + 0.2 V, low noise, LVDS-
compatible output drivers, and TTL/CMOS latch inputs with
adjustable hysteresis and/or shutdown inputs.
The device offers 1.6 ns propagation delay 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 +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, 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 AD8465 is available in a 12-lead LFCSP.
