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.

Ordering Information

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.
