ISL55020
FN6287.0
Wideband, Low Distortion, Differential
Amplifier
The ISL55020 is fully differential wideband amplifier
designed to drive differential ADCs. This device features a
high drive capability of 100mA, low operating quiescent
current of 21mA and operates with both single and dual
supplies over a range of 4.5V (±2.25V) to +12V (±6V). Key
features include high impedance, full differential inputs and
full differential or DC referenced complementary single-
ended outputs A wide bandwidth unity gain common mode
(VCM) amplifier input is included to provide DC offset
correction or common mode signal injection to the
differential output.
The ISL55020 is available in the thermally-enhanced 16 Ld
QFN package and is specified for operation over the full
-40°C to +85°C temperature range. The ISL55020 has an
EN pin to disable the outputs.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
