GENERAL DESCRIPTION
+IN A
V–
The AD8531, AD8532 and AD8534 are single, dual and quad
rail-to-rail input and output single-supply amplifiers featuring
250 mA output drive current. This high output current makes
these amplifiers excellent for driving either resistive or capacitive
loads. AC performance is very good with 3 MHz bandwidth,
5 V/µs slew rate and low distortion. All are guaranteed to oper-
ate from a +3 volt single supply as well as a +5 volt supply.
The very low input bias currents enable the AD853x to be used
for integrators and diode amplification and other applications
requiring low input bias current. Supply current is only 750
µA
per amplifier at 5 volts, allowing low current applications to
control high current loads.
Applications include audio amplification for computers, sound
ports, sound cards and set-top boxes. The AD853x family is
very stable and capable of driving heavy capacitive loads, such as
those found in LCDs.
The ability to swing rail-to-rail at the inputs and outputs enables
designers to buffer CMOS DACs, ASICs or other wide output
swing devices in single-supply systems.
The AD8531, AD8532 and AD8534 are specified over the
extended industrial (–40°C to +85°C) temperature range. The
AD8531 is available in SO-8 and SOT-23-5 packages. The
AD8532 is available in 8-lead plastic DIP, SO-8, 8-lead MSOP
and 8-lead TSSOP surface-mount packages. The AD8534 is
available in 14-lead plastic DIP, narrow SO-14 and 14-lead
TSSOP surface-mount packages. All TSSOP and SOT versions
are available in tape and reel only.
