AD8469 Data Sheet
FEATURES GENERAL DESCRIPTION Qualified for automotive applications
Fully specified rail-to-rail at VCC = 2.5 V to 5.5 V
Input common-mode voltage: VEE − 0.2 V to VCC + 0.2 V
Low glitch TTL-/CMOS-compatible output stage
40 ns propagation delay
Low power: 1.4 mW at 2.5 V
Shutdown pin

Power supply rejection better than −50 dB
−40°C to +125°C operation The AD8469 is a fast comparator fabricated on XFCB2, an
Analog Devices, Inc., proprietary process. This comparator is
exceptionally versatile and easy to use. Features include an input
range from VEE − 0.2 V to VCC + 0.2 V, low noise, TTL-and
CMOS-compatible output drivers, adjustable hysteresis control,
and a shutdown input. The device offers a 40 ns propagation
delay driving a 15 pF load with 10 mV overdrive on 500 µA
typical supply current.
A flexible power supply scheme allows the device to operate
from a single +2.5 V positive supply with a −0.2 V to +2.7 V
input signal range up to a +5.5 V positive supply with a −0.2 V …
