DG408DY/R70865

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408DY/R70865 is an improved CMOS analog multiplexer switch manufactured by Analog Devices Inc. (Maxim Integrated). It features a single 8:1 configuration housed in a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a channel-to-channel matching of 1.5 Ohms, and a charge injection of 2pC. Switching times are limited to 150ns for both turn-on and turn-off periods. The component supports an operating temperature range of -40°C to +85°C and exhibits low off-state leakage current of 500pA.
