GENERAL DESCRIPTION

The AD8138-EP is a major advancement over op amps for differential signal processing. The AD8138-EP can be used
as a single-ended-to-differential amplifier or as a differential-to- differential amplifier. The AD8138-EP is as easy to use as an op amp and greatly simplifies differential signal amplification and driving. Manufactured on Analog Devices, Inc., proprietary XFCB bipolar process, the AD8138-EP 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-EP has a unique internal feedback feature that provides balanced output gain and phase matching, suppressing even order harmonics. The internal feedback circuit also minimizes any gain error that would be associated with the mismatches in the external gain setting resistors.
