GENERAL DESCRIPTION
The AD8519 and AD8529 are rail-to-rail output bipolar amplifi-
ers with a unity gain bandwidth of 8 MHz and a typical voltage
offset of less than 1 mV. The AD8519 brings precision and band-
width to the SOT-23 package. The low supply current makes the
AD8519/AD8529 ideal for battery powered applications. The
rail-to-rail output swing of the AD8519/AD8529 is larger than
standard video op amps, making them useful in applications that
require greater dynamic range than standard video op amps. The
+2.7 V/
s slew rate makes the AD8529/AD8549 a good match
for driving ASIC inputs such as voice codecs.
The small SOT-23 package makes it possible to place the AD8519
next to sensors, reducing external noise pickup.
The AD8519/AD8529 is specified over the extended industrial
(40
C to +125
C) temperature range. The AD8519 is avail-
able in 5-lead SOT-23-5 and SO-8 surface mount packages.
The AD8529 is available in 8-lead SOIC and
SOIC packages.
