DG423DN

Analog Switches, Multiplexers, Demultiplexers Overview

The DG423DN is a dual SPDT analog switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a PLCC-20 surface-mount package. It operates on single or dual power supplies ranging from 10 V to 30 V (single) or ±4.5 V to ±20 V (dual). Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum switching time of 250 ns, and a maximum off-time of 200 ns. The device supports a DC switch current of 20 mA with a maximum power dissipation of 800 mW and a maximum supply current of 1 uA. It functions within an operating temperature range of -40°C to +85°C.
