GENERAL DESCRIPTION

The ADG936/ADG936-R are wideband analog switches that

comprise two independently selectable SPDT switches using a

CMOS process to provide high isolation and low insertion loss

to 1 GHz. The ADG936 is an absorptive/matched dual SPDT

with 50 Ω terminated shunt legs; the ADG936-R is a reflective

dual SPDT. These devices are designed such that the isolation is

high over the dc to 1 GHz frequency range. They have on-board

CMOS control logic, eliminating the need for external

controlling circuitry. The control inputs are both CMOS and

Rev. 0
