GENERAL DESCRIPTION  
The AD8138 is a major advancement over op amps for  
differential signal processing. The AD8138 can be used as a  
single-ended-to-differential amplifier or as a differential-to-  
differential amplifier. The AD8138 is as easy to use as an op  
amp and greatly simplifies differential signal amplification and  
driving. Manufactured on ADIs proprietary XFCB bipolar  
process, the AD8138 has a −3 dB bandwidth of 320 MHz and  
delivers a differential signal with the lowest harmonic distortion  
available in a differential amplifier. The AD8138 has a unique  
internal feedback feature that provides balanced output gain  
and phase matching, suppressing even order harmonics. The  
internal feed-back circuit also minimizes any gain error that  
would be associated with the mismatches in the external gain  
setting resistors.  
The AD8138 eliminates the need for a transformer with high  
performance ADCs, preserving the low frequency and dc infor-  
mation. The common-mode level of the differential output is  
adjustable by a voltage on the VOCM pin, easily level-shifting the  
input signals for driving single-supply ADCs. Fast overload  
recovery preserves sampling accuracy.  
The AD8138 distortion performance makes it an ideal ADC  
driver for communication systems, with distortion performance  
good enough to drive state-of-the-art 10-bit to 16-bit converters  
at high frequencies. The AD8138s high bandwidth and IP3 also  
make it appropriate for use as a gain block in IF and baseband  
signal chains. The AD8138 offset and dynamic performance  
makes it well suited for a wide variety of signal processing and  
data acquisition applications.  
The AD8138s differential output helps balance the input to  
differential ADCs, maximizing the performance of the ADC.  
The AD8138 is available in both SOIC and MSOP packages for  
operation over −40°C to +85°C temperatures.
