GENERAL DESCRIPTION
The AD8519 and AD8529 are rail-to-rail output bipolar
amplifiers with a unity gain bandwidth of 8 MHz and a typical
voltage offset of less than 1 mV. The AD8519 brings precision
and bandwidth to the SC70 and SOT-23 packages. 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 2.9 V/μs slew rate makes the
AD8519/AD8529 a good match for driving ASIC inputs such as
voice codecs.
The small SC70 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 available
in 5-lead SC70 and 5-lead SOT-23 packages, and an 8-lead
SOIC surface-mount package. The AD8529 is available in 8-lead
SOIC and 8-lead MSOP packages.
