DG423DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG423DJ 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 10V to 30V (single) or ±4.5V to ±20V (dual). Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum supply current of 1 µA, and a DC switch current of 20 mA. The device supports a maximum data rate with a turn-on time of 250 ns and a turn-off time of 200 ns. It functions within an operating temperature range of -40°C to +85°C and has a maximum power dissipation of 800 mW.
