GENERAL DESCRIPTION

The AD8517 brings precision and bandwidth to the SOT-23-5

package even at single supply voltages as low as 1.8 V. The

small package makes it possible to place the AD8517 next to

sensors, reducing external noise pickup. The AD8527 dual

amplifier is offered in the space-saving MSOP package.

The AD8517 and AD8527 are rail-to-rail input and output

bipolar amplifiers with a gain bandwidth of 7 MHz and typical

voltage offset of 1.3 mV from a 1.8 V supply. The low supply

current makes these parts ideal for battery-powered applications.

The 8 V/µs slew rate makes the AD8517/AD8527 a good match

for driving ASIC inputs, such as voice codecs.

The AD8517/AD8527 is specified over the extended industrial

(–40°C to +125°C) temperature range. The AD8517 single is

available in 5-lead SOT-23 surface-mount packages. The dual

AD8527 is available in 8-lead SOIC and MSOP packages.
