GENERAL DESCRIPTIONThe 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 SOT-23-5L and
SC70-5L 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/ms slew rate
makes the AD8515 a good match for driving ASIC inputs, such
as voice codecs.
The AD8515 is specified over the extended industrial tempera-
ture range (–40∞C to +125∞C).

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
AD8515 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.
