The AD8138A is a major advancement over op amps for differential signal processing. The AD8138A can be used as a single-ended-to-differential amplifier or as a differential-to- differential amplifier. The AD8138A is as easy to use as an op amp and greatly simplifies differential signal amplification and driving. Manufactured on the Analog Devices, Inc., proprietary XFCB bipolar process, the AD8138A has a −3 dB bandwidth of 300 MHz and delivers a differential signal with low harmonic distortion. The AD8138A has a unique internal feedback feature that provides balanced output gain and phase matching, suppressing even- order harmonics. The internal feedback circuit minimizes any gain error that is associated with the mismatches in the external gain setting resistors. The differential output of the AD8138A helps balance the input to differential analog-to-digital converters (ADCs), maximizing the performance of the ADC. The AD8138A 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 AD8138A 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 high bandwidth and IP3 of the AD8138A make it appropriate for use as a gain block in IF and baseband signal chains. The AD8138A offset and dynamic performance makes it well-suited for a wide variety of signal processing and data acquisition applications. The AD8138A is available in both SOIC and MSOP packages for operation over the −40°C to +85°C temperature range.
