AO321
OP AMPLIFIER
1MHz CMOS RAIL-TO-RAIL IO OPAMP WITH RF FILTER
DESCRIPTION
FEATURES
The AO321 family have a high gain-bandwidth
product of 1MHz, a slew rate of 0.6V/μs, and a
quiescent current of 40 μ A/amplifier at 5V. The
AO321 family is designed to provide optimal
performance in low voltage and low noise systems.
They provide rail-to-rail output swing into heavy
loads. The input common mode voltage range
includes ground, and the maximum input offset
voltage is 3.5mV for AO321 family. They are
specified over the extended industrial temperature
range (-40to +125). The operating range is
from 2.1V to 5.5V.
The AO321 is available in SC70-5 and SOT-25
packages.
