GENERAL DESCRIPTION
The AD8615, AD8616 and AD8618 are single, dual and quad
rail-to-rail input and output single supply amplifiers featuring
very low offset voltage, wide signal bandwidth, and low input
voltage and current noise. These amplifiers use a patented
trimming technique that achieves superior precision without
laser trimming. All are fully specified to operate from +3V to
+5V single supply.
The combination of low offsets, low noise, very low input bias
currents, and high speed make these amplifiers useful in a wide
variety of applications. Filters, integrators, photo-diode
amplifiers and high impedance sensors all benefit from the
combination of performance features. Audio and other AC
applications benefit from the wide bandwidth and low
distortion.
AD8618, quad, is available in 14-lead TSSOP and narrow 14pin SOIC packages.
SOT, MSOP and TSSOP versions are available in tape and
reel only.

Applications for these amplifiers include Portable and looppowered instrumentation, audio amplification for portable
devices, portable phone headsets, bar code scanners, and
multi-pole filters. The ability to swing rail-to-rail at both the
input and output enables designers to buffer CMOS ADCs,
DACs, ASICs and other wide output swing devices in single
supply systems.
The AD8615, AD8616 and AD8618 are specified over the
extended industrial (-40° to +125°C) temperature range. The
AD8615, single, is available in the tiny 5-lead SOT-23
package. The AD8616, dual, is available in the 8-lead microSOIC and narrow SOIC surface mount packages. The

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 this device 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.
