AD8138SRMZ-EP-R7

AD8138-EP is a low distortion differential ADC driver. It is a major advancement over op-amps for differential signal processing. It can be used as a single-ended-to-differential amplifier or as a differential-to-differential amplifier. It 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, this device has a -3dB bandwidth of 320MHz and delivers a differential signal with the lowest harmonic distortion available in a differential amplifier. It 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. It is used in applications such as ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers, line drivers.
