PRODUCT DESCRIPTION
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 simpli-
fies 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. The AD8138 has a unique internal
feedback feature that provides output gain and phase matching
that are balanced, suppressing even order harmonics. The internal
feedback circuit also minimizes any gain error that would be asso-
ciated with the mismatches in the external gain setting resistors.
The AD8138’s differential output helps balance the input-to-
differential ADCs, maximizing the performance of the ADC.
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 V
OCM
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- 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 per-
formance make it well suited for a wide variety of signal
processing and data acquisition applications.
The AD8138 is available in both SOIC and MICRO_SOIC
packages for operation over –40
°
C to +85
°
C temperatures.
