GENERAL DESCRIPTION
The AD8615/AD8616/AD8618 are single/dual/quad, rail-torail, input
and output, single-supply amplifiers featuring very low offset
voltage, wide signal bandwidth, and low input voltage and current
noise. The parts use a patented trimming technique that achieves
superior precision without laser trimming. The AD8615/AD8616/AD8618
are fully specified to operate from 2.7 V to 5 V single supplies.
The combination of >20 MHz bandwidth, low offset, low noise, and
low input bias current makes these amplifiers useful in a wide
variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from the
combination of performance features. AC applications benefit from
the wide bandwidth and low distortion. The AD8615/AD8616/ AD8618
offer the highest output drive capability of the DigiTrim® family,
which is excellent for audio line drivers and other low impedance
applications.
Applications for the parts include portable and low powered
instrumentation, audio amplification for portable devices, portable
phone headsets, bar code scanners, and multipole 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/AD8618 are specified over the extended industrial
temperature range (−40°C to +125°C). The AD8615 is available in
5-lead TSOT-23 package. The AD8616 is available in 8-lead MSOP and
narrow SOIC surface-mount packages; the MSOP version is available
in tape and reel only. The AD8618 is available in 14-lead SOIC and
TSSOP packages.
