DG441DYZA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441DYZA-T is a monolithic CMOS analog switch IC manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches in a 16-pin SOIC-Narrow package. The device supports single supply voltages from 5V to 34V or dual supplies of ±5V to ±22V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum switching time of 250ns, and an off-time of 120ns. It operates within a temperature range of -40°C to +85°C and features a maximum power dissipation of 1.6mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer date code and lot traceability against the specific order requirements. Confirm RoHS compliance status as indicated in the latest datasheet revision. Ensure the SOIC-Narrow 16 package dimensions match the PCB footprint specifications. Check for any recent Product Change Notifications regarding labeling or material composition updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog channels are required in a compact surface-mount package. Compare on-resistance and leakage current specifications against alternative devices if signal integrity is critical. Ensure the operating voltage range aligns with the system's power supply rails. Consider the thermal performance given the 1.6mW power dissipation rating in enclosed environments.
