GENERAL DESCRIPTION

The AD8468 is a fast comparator fabricated on XFCB2.0, an

Analog Devices, Inc., proprietary process. This comparator is

exceptionally versatile and easy to use. Features include an input

range from −0.2 V to V_CC+ 0.2 V, low noise, TTL-/CMOS-

compatible output drivers, and shutdown inputs. The device

offers 40 ns propagation delays driving a 15 pF load with 10 mV

overdrive on 500 µA typical supply current.

The TTL-/CMOS-compatible output stage is designed to drive

up to 15 pF with full rated timing specifications and to degrade

in a graceful and linear fashion as additional capacitance is

added. The input stage of the comparator offers robust protec-

tion against large input overdrive, and the outputs do not phase

reverse when the valid input signal range is exceeded.

The AD8468 is available in a tiny 6-lead SC70 package with a

single-ended output and a shutdown pin.

A flexible power supply scheme allows the device to operate

with a single 2.5 V positive supply with a −0.2 V to + 2.7 V

input signal range and up to a 5.5 V positive supply with a

−0.2 V to +5.7 V input signal range.
