Description

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 singleended 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 -40C to +85C temperature range. The ISL55020 has an EN pin to disable the outputs.
