AD8138ARMZ

The AD8138ARMZ is one member of the AD8138 series.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 ADI's 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.

Features of the AD8138ARMZ are:(1)easy to use, single-ended-to-differential conversion; (2)adjustable output common-mode voltage; (3)externally adjustable gain; (4)fast settling to 0.01% of 16 ns; (5)slew rate 1150 V/s; (6)fast overdrive recovery of 4 ns; (7)low input voltage noise of 5 nV/Hz; (8)1 mV typical offset voltage; (9)wide supply range +3 V to ±5 V; (10)low power 90 mW on 5 V; (11)0.1 dB gain flatness to 40 MHz; (12)available in 8-Lead SOIC and MSOP packages.

The absolute maximum ratings of the AD8138ARMZ can be summarized as:(1)supply voltage:±5.5 V;(2)VOCM:±VS;(3)internal power dissipation:550 mW;(4)storage temperature range:-65 to +150;(5)operating temperature range:-40 to +85;(6)junction temperature:150.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.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 AD8138's 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.
