Precision, 20 MHz, CMOS, Rail-to-Rail
Input/Output Operational Amplifiers
AD8615/AD8616/AD8618
FEATURES
Low offset voltage: 65 μV max
Single-supply operation: 2.7 V to 5.5 V
Low noise: 8 nV/√Hz
Wide bandwidth: >20 MHz
Slew rate: 12 V/μs
High output current: 150 mA
No phase reversal
Low input bias current: 1 pA
Low supply current: 2 mA
Unity-gain stable
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 very low input bias current make 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
TM
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 (–40°C to +125°C) temperature range. The AD8615
is available in 5-lead TSOT-23 packages. The AD8616 is availa-
ble 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.
APPLICATIONS
Barcode scanners
Battery-powered instrumentation
Multipole filters
Sensors
ASIC input or output amplifier
Audio
Photodiode amplification
GENERAL DESCRIPTION
The AD8615/AD8616/AD8618 are dual/quad, rail-to-rail, input
and output, single-supply amplifiers featuring very low offset
voltage, wide signal bandwidth, and low input voltage and
