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.
