DG418CY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG418CY+T is a precision CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a single SPST configuration housed in an 8-SOIC surface-mount package. The device supports dual supply voltages ranging from ±4.5 V to ±20 V or a single supply of 10 V to 30 V. Key electrical specifications include a maximum on-resistance of 35 Ohms, a channel-to-channel matching of 3 Ohms, and a leakage current of 250 pA. Switching times are specified at a maximum of 175 ns for turn-on and 145 ns for turn-off. The component operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as '+T' variants typically adhere to environmental standards. Check manufacturer documentation for lead-free soldering profiles compatible with the SOIC-8 package. Ensure availability aligns with current production lifecycle status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications demanding low on-resistance variation between channels. The SOIC-8 package suits space-constrained surface-mount designs. Verify that the required voltage range fits within the ±4.5 V to ±20 V dual supply limits. Consider the 175 ns switching speed for timing-critical digital control interfaces.

Analog Switches, Multiplexers, Demultiplexers Part Context
