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.
