GENERAL DESCRIPTION
The ADL5566 is a high performance, dual differential amplifier
optimized for IF and dc applications. The amplifier offers low
noise of 1.3 nV/√Hz and excellent distortion performance over
a wide frequency range, making it an ideal driver for high speed
16-bit analog-to-digital converters (ADCs). The ADL5566 is
ideally suited for use in high performance, zero IF/complex
IF receiver designs. In addition, this device has excellent low
distortion for single-ended input drive applications.
The ADL5566 provides a gain of 16 dB. For the single-ended input
configuration, the gain is reduced to 14 dB. Using two external
series resistors for each amplifier expands the gain flexibility of
the amplifier and allows for any gain selection from 0 dB to 16 dB
for a differential input and 0 dB to 14 dB for a single-ended input.
In addition, this device maintains low distortion down to output
(VOCM) levels of 1.2 V providing an added capability for driving
CMOS ADCs at ac levels up to 2 V p-p.

ADL5566
The quiescent current of the ADL5566, using a 3.3 V supply, is
typically 70 mA per amplifier. When disabled, it consumes less
than 3.5 mA per amplifier and has −25 dB of input-to-output
isolation at 100 MHz.
The device is optimized for wideband, low distortion, and noise
performance, giving it unprecedented performance for overall
spurious-free dynamic range (SFDR). These attributes, together
with its adjustable gain capability, make this device the amplifier
of choice for driving a wide variety of ADCs, mixers, pin diode
attenuators, SAW filters, and multi-element discrete devices.
Fabricated on an Analog Devices, Inc., high speed SiGe process, the
ADL5566 is supplied in a compact 4 mm × 4 mm, 24-lead LFCSP
package and operates over the −40°C to +85°C temperature range.
