FN6287.0
Wideband, Low Distortion, Differential
Amplifier
Features
• Fully differential current feedback amplifier
• High impedance differential inputs
• Differential output drives up to 100mA from a +12V supply
• Separate unity-gain common mode input (VCM)
• 300MHz bandwidth
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.
• 1200V/µs Slewrate
• -73.3dBc typical driver output distortion at 10V ; 1MHz
PP
• -64.6dBc typical driver output distortion at 10V ; 4MHz
PP
• Low quiescent supply current of 21mA
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.
• Pb-free plus anneal available (RoHS compliant)
Applications
• High Linearity ADC preamplifier
• Differential driver

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.
