Overview
The DG441DYZA is a quad single-pole single-throw (SPST) analog switch integrated circuit manufactured by Renesas Electronics Corporation. It features four independent channels in a 16-pin plastic small outline package (SOIC). The device supports dual power supplies ranging from ±5 V to ±22 V or a single supply from 5 V to 34 V. Key electrical specifications include a maximum on-resistance of 85 Ohms, a maximum switching time of 250 ns, and an off-time of 120 ns. The operating temperature range extends from -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches within a single compact package
- Supports flexible dual or single power supply configurations for broad system compatibility
- Provides high channel isolation with low charge injection characteristics
Applications
- Signal routing in data acquisition systems
- Audio signal path switching
- Instrumentation front-end multiplexing
Procurement Notes
Verify the specific suffix 'A' against the official Renesas datasheet to confirm pinout and electrical tolerances match the design requirements. Ensure the component source is authorized to guarantee authenticity and traceability. Check RoHS compliance status as indicated in the manufacturer's documentation before final procurement.
Selection Notes
Select this component when a quad SPST configuration is required for moderate-speed analog signal switching. The 85 Ohm on-resistance is suitable for general-purpose applications but may require consideration for high-precision low-voltage signals. Verify that the 16-pin SOIC package fits the available PCB footprint and thermal constraints.
Part Context
The DG441 series belongs to Renesas' portfolio of complementary metal-oxide-semiconductor (CMOS) analog switches. This family is designed for applications requiring multiple isolated signal paths. The DG441DYZA specifically denotes the SOIC-16 package variant within the broader DG441 product line.
Replacement Considerations
Compatible substitutes include the DG441DVZ (TSSOP-16 package) and DG441DJZ (PDIP-16 package). These variants share identical electrical characteristics but differ in physical package dimensions and mounting style.
