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 ampli-
fier. 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. The AD8138 has a unique internal
feedback feature that provides output gain and phase matching
that are balanced, suppressing even order harmonics. The inter-
nal feedback circuit also minimizes any gain error that would be
associated 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 VOCM 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 pro-
cessing and data acquisition applications.
The AD8138 is offered in an 8-lead SOIC that operates over
the industrial temperature range of –40°C to +85°C.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8138 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
