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.

Information furnished by Analog Devices is believed to be accurate and reliable. However, no
responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other
rights of third parties that may result from its use. Specifications subject to change without notice. No
license is granted by implication or otherwise under any patent or patent rights of Analog Devices.
Trademarks and registered trademarks are the property of their respective owners.
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.
