MAX4635ETB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4635ETB-T is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V. The device features a maximum on-resistance of 4 ohms and offers fast switching times with a maximum turn-on time of 14ns and turn-off time of 6ns. Key electrical specifications include a charge injection of 2pC, channel capacitance of 9pF, and leakage current of 100pA. It provides -67dB crosstalk at 1MHz and maintains channel-to-channel matching within 100 milliohms. The component is housed in a 10-WFDFN package with exposed pad and supports an operating temperature range of -40°C to +85°C.
