MAX335CWG+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX335CWG+T is a CMOS analog switch IC featuring eight independently controlled single-pole-single-throw (SPST) switches. It operates with dual power supplies ranging from ±4.5V to ±20V and handles rail-to-rail analog signals. The device utilizes an SPI-compatible serial interface for control, allowing multiple units to be daisy-chained. Key electrical parameters include a typical on-resistance of 100Ω, maximum off-isolation of 90dB at 100kHz, and channel-to-channel crosstalk of 100dB. The component supports a maximum clock frequency of 2.1MHz and functions within a commercial temperature range of 0°C to +70°C.
