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.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

For supply voltages less than 6 V the input voltage is limited to less than or equal
to the supply voltage.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8517/AD8527 features proprietary ESD protection circuitry, permanent dam-
age may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.
