Precision, 20 MHz, CMOS, Rail-to-Rail  
Input/Output Operational Amplifiers  
AD8615/AD8616/AD8618  
FEATURES  
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.  
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  
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 DigiTrimTM family, which is excellent for audio  
line drivers and other low impedance applications.  
APPLICATIONS  
Barcode scanners  
Battery-powered instrumentation  
Multipole filters  
Sensors  
ASIC input or output amplifier  
Audio  
Photodiode amplification  
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.  
GENERAL DESCRIPTION  
The AD8615/AD8616/AD8618 are specified over the extended  
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  
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.
