MAX4800CXZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800CXZ-T is an eight-channel high-voltage analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It utilizes BCDMOS process technology to provide low-charge-injection SPST switches controlled via a digital serial interface. The device supports flexible high-voltage supplies with VPP - VNN up to 200V, including configurations such as +100V/-100V, +185V/-15V, and +40V/-160V. The digital logic operates on a separate VDD supply ranging from +2.7V to +13.2V, with inputs tolerant up to +13.2V. It features a power-on reset function ensuring all switches are open upon initialization.
