capacitive loads up to 15 pF. If driving larger capacitive loads,  
a small series resistor is needed to avoid excessive peaking or  
overshoot.  
The AD8039 amplifier is the only dual, low power, high speed  
amplifier available in a tiny SOT-23-8 package, and the single  
AD8038 is available in both a SOIC-8 and an SC70-5 package.  
These amps are rated to work over the industrial temperature  
range of 40°C to +85°C.  
PRODUCT DESCRIPTION  
The AD8038 (single) and AD8039 (dual) amplifiers are high  
speed (350 MHz) voltage feedback amplifiers with an exception-  
ally low quiescent current of 1.0 mA/amplifier typical (1.5 mA max).  
The AD8038 single amplifier in the SOIC-8 package has a dis-  
able 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 low input offset voltage of  
3 mV max.

ADIs 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 band-  
width, 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 will swing within 1 V of  
each rail on the output. These amplifiers are optimized for driving
