DG509AMY/PR

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509AMY/PR is a dual SP4T analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent multiplexer circuits, each configured as a single-pole quadruple-throw switch with a maximum on-resistance of 450 ohms. The device operates within a supply voltage range of ±4.5V to ±18V and supports a single supply of 4.5V to 18V. It is housed in a 20-pin PLCC surface-mount package and is rated for an operating temperature range of -20°C to +85°C.
