DG442CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442CEE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 10 V to 30 V for single supplies or ±4.5 V to ±20 V for dual supplies. The device features a maximum on-resistance of 85 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 250 ns and a maximum turn-off time of 170 ns. It is housed in a TQFN-16 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
