GENERAL DESCRIPTION  
The AD8038 (single) and AD8039 (dual) amplifiers are high speed  
(350 MHz) voltage feedback amplifiers with an exceptionally low  
quiescent current of 1.0 mA/amplifier typical (1.5 mA maximum).  
The AD8038 single amplifier in the 8-lead SOIC package has a  
disable feature. Despite being low power and low cost, the amplifier  
provides excellent overall performance. Additionally, it offers a  
high slew rate of 425 V/μs and a low input offset voltage of 3 mV  
maximum.  
The AD8039 amplifier is available in a 8-lead SOT-23 package,  
and the single AD8038 is available in both an 8-lead SOIC and a  
5-lead SC70 package. These amplifiers are rated to work over  
the industrial temperature range of −40°C to +85°C.

The Analog Devices, Inc., proprietary XFCB process allows low  
noise operation (8 nV/√Hz and 600 fA/√Hz) at extremely low  
quiescent currents. Given a wide supply voltage range (3 V to 12 V),  
wide bandwidth, and small packaging, the AD8038 and AD8039  
amplifiers are designed to work in a variety of applications  
where power and space are at a premium.

The AD8038 and AD8039 amplifiers have a wide input common-  
mode range of 1 V from either rail and swing to within 1 V of each  
rail on the output. These amplifiers are optimized for driving  
capacitive loads up to 15 pF. If driving larger capacitive loads, a small  
series resistor is needed to avoid excessive peaking or overshoot.
