GENERAL DESCRIPTION

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 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 V_EE− 0.5 V to V_CCI+ 0.2 V, low noise, LVDS-

compatible output drivers, and TTL/CMOS latch inputs with

adjustable hysteresis and/or shutdown inputs.

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 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.

The AD8465 is available in a 12-lead LFCSP.
