GENERAL DESCRIPTION
The ADL5567 is a high performance, dual differential amplifier
optimized for intermediate frequencies (IF) and dc applications.
The amplifier offers a low noise of 1.29 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 ADL5567 is ideally suited for use in high performance
zero-IF and complex IF receiver designs. In addition, this device
has excellent low distortion for single-ended input driver
applications.
The ADL5567 provides a gain of 20 dB. For the single-ended input
configuration, the gain is reduced to 18 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 20 dB
for a differential input and 0 dB to 18 dB for a single-ended input.
In addition, this device maintains low distortion down to output
common-mode levels of 1.25 V, and therefore providing an added
capability for driving CMOS ADCs at ac levels up to 2 V p-p.

The quiescent current of the ADL5567 using a 5 V supply is
typically 74 mA per amplifier in high performance mode. When
disabled, each amplifier consumes only 3.5 mA, and has 58 dB
input to output isolation at 100 MHz.
The device is optimized for wideband, low distortion, and low
noise operation, 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 multielement discrete devices.
Fabricated on an Analog Devices, Inc., high speed silicon
germanium (SiGe) process, the ADL5567 is supplied in a
compact 4 mm × 4 mm, 24-lead LFCSP package and operates
over the −40°C to +85°C temperature.
