MAX4800ACCM+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4800ACCM+T is an eight-channel high-voltage analog switch IC utilizing BCDMOS technology. It features a 20MHz SPI serial interface and operates with VPP/VNN supplies of +100V/-100V, +185V/-15V, or +40V/-160V. The digital logic supply (VDD) ranges from +2.7V to +6V. Typical on-resistance is 22Ω at +25°C. The device provides low charge injection, -77dB off-isolation at 5MHz, and 10µA quiescent current. It is housed in a 48-pin LQFP package and supports commercial temperature operation from 0°C to +70°C.
