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
analog-to-digital converters (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.
