GENERAL DESCRIPTION
The ADL5562 is a high performance differential amplifier
optimized for RF and IF applications. The amplifier offers low
noise of 2.1 nV/√Hz and excellent distortion performance over
a wide frequency range, making it an ideal driver for high speed
8-bit to 16-bit ADCs.
The ADL5562 provides three gain levels of 6 dB, 12 dB, and
15.5 dB through a pin-strappable configuration. For the single-
ended input configuration, the gains are reduced to 5.6 dB,
11.1 dB, and 14.1 dB. Using an external series input resistor
expands the amplifier gain flexibility and allows for any gain
selection from 0 dB to 15.5 dB.
The quiescent current of the ADL5562 is typically 80 mA and,
when disabled, consumes less than 3 mA, offering excellent
input-to-output isolation.

The device is optimized for wideband, low distortion performance.
These attributes, together with its adjustable gain capability,
make this device the amplifier of choice for general-purpose IF
and broadband applications where low distortion, noise, and power
are critical. This device is optimized for the best combination of
slew speed, bandwidth, and broadband distortion. These attributes
allow it to drive a wide variety of ADCs and make it ideally suited
for driving mixers, pin diode attenuators, SAW filters, and multi-
element discrete devices.
Fabricated on an Analog Devices, Inc., high speed SiGe process,
the ADL5562 is supplied in a compact 3 mm × 3 mm, 16-lead
LFCSP package and operates over the temperature range of
−40°C to + 85°C.
