GENERAL DESCRIPTION
The AD8515 is a rail-to-rail amplifier that can operate from
a single-supply voltage as low as 1.8 V.
The AD8515 single amplifier, available in 5-lead SOT-23 and 5-lead
SC70 packages, is small enough to be placed next to sensors,
reducing external noise pickup.

The AD8515 is a rail-to-rail input and output amplifier with
a gain bandwidth of 5 MHz and typical offset voltage of 1 mV
from a 1.8 V supply. The low supply current makes these parts
ideal for battery-powered applications. The 2.7 V/μs slew rate
makes the AD8515 a good match for driving ASIC inputs such
as voice codecs.
The AD8515 is specified over the extended industrial
temperature range of −40°C to +125°C.
