Overview
The AD75019JP, produced by Analog Devices Inc., is a 16 × 16 crosspoint switch array integrated circuit. This device contains 256 analog switches, allowing any of the X or Y pins to serve as inputs or outputs. The switches can connect any or all of the X terminals to any or all of the Y terminals, accommodating signals with amplitudes up to the supply rails. The AD75019JP is fabricated using Analog Devices’ BiMOS II process, which combines CMOS devices for low distortion switches and bipolar devices for ESD protection.
