The AD75019 is a 16×16 array of 256 analog switches. It features a wide signal range, low on-resistance, and TTL/CMOS/microprocessor-compatible control lines.
The AD75019 contains 256 analog switches arranged in a 16 × 16 matrix. Each switch can handle signal amplitudes up to the supply rails and has a typical on‑resistance of 150 Ω. Data is loaded serially into a 256‑bit shift register and then latched for static operation.
The device operates from dual analog supplies (Vpp and Vss) and a digital supply (Vcc). It supports cascade operation via the SOUT pin, allowing multiple devices to be linked for larger switch matrices. The datasheet provides electrical specifications, pin descriptions, timing characteristics, and layout dimensions.
