DG408C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The DG408C/D is a CMOS analog multiplexer die configured as a 1-of-8 channel switch. It operates with single supplies from +5V to +30V or dual supplies from ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 100Ω, guaranteed channel matching of 8Ω max, and flatness of 9Ω max. Charge injection is limited to 15pC max, while input leakage remains below 5nA at +85°C. The device supports rail-to-rail signal handling and features digital inputs compatible with TTL/CMOS logic levels.
