DG403DY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403DY+T is a dual high-speed analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two single-pole double-throw (SPDT) channels housed in a 16-pin SOIC narrow surface-mount package. The device operates on a single supply voltage ranging from 10 V to 30 V or dual supplies from ±4.5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 45 Ohms, a maximum power dissipation of 696 mW, and a maximum supply current of 1 uA. Switching performance is defined by a maximum turn-on time of 150 ns and a maximum turn-off time of 100 ns. The component supports an operating temperature range from -40°C to +85°C.
