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.
