DG406CWI+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG406CWI+ is a CMOS analog multiplexer featuring a 1-of-16 channel configuration housed in a 28-pin Wide SO package. It operates with single supplies from +5V to +30V or dual supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 175Ω under single supply conditions and 125Ω under dual supply conditions, with a maximum on-resistance matching of 8Ω. The device guarantees low charge injection of 15pC (max) and input off-leakage current below 5nA at +85°C. Digital inputs are TTL/CMOS compatible, and the component supports an operating temperature range of 0°C to +70°C.
