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.
Feature Summary
- Integrates four independent SPST analog switches with TTL and CMOS compatible digital inputs.
- Features low charge injection characteristics suitable for sample and hold applications.
- Utilizes a high voltage silicon-gate process with epitaxial layer to prevent latch-up.
Applications
- Data acquisition systems requiring signal routing.
- Sample and hold circuits in instrumentation.
- High impedance sensing interfaces.
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.
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.
Part Context
This part belongs to the DG441 series of quad SPST analog switches. It serves as a drop-in replacement for older discrete switch solutions. The device is part of Renesas' broader portfolio of analog signal chain components designed for industrial and consumer applications.
Replacement Considerations
DG441DYZA is the non-tape variant of the same device. DG441DVZ offers the same functionality in a TSSOP-16 package. Verify pin compatibility before substituting with different package types.
