DG444CJ+

Overview

The DG444CJ+ is a monolithic, quad single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent switches with an on-resistance of 85Ω maximum and an on-resistance match between channels of 4Ω maximum. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a turn-on time of 250ns maximum, a turn-off time of 120ns maximum, and charge injection of 10pC maximum. It is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

Improved on-resistance matching between channels for enhanced signal integrity
Guaranteed low charge injection simplifying sample-and-hold applications
TTL and CMOS logic compatible inputs for versatile control integration

Applications

Sample-and-Hold Circuits
Test Equipment
Audio Signal Routing
Communication Systems

Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated in the ordering information table. Ensure the component source matches the manufacturer designation for Analog Devices Inc./Maxim Integrated to guarantee authenticity and performance specifications.

Selection Notes

Select this component when a quad SPST configuration with improved channel-to-channel resistance matching is required. The device is suitable for applications needing rail-to-rail signal handling and low power consumption. Consider the PDIP-16 package constraints for through-hole mounting requirements and verify that the bipolar or single supply voltage ranges align with the system design.

Part Context

The DG444 series serves as a redesigned upgrade to the industry-standard DG211 and DG212 devices. It offers lower on-resistance and faster switching times compared to its predecessors. The DG444 variant specifically provides four normally closed switches, distinguishing it from the DG445 which contains normally open switches. Both share identical pinouts and electrical characteristics except for the logic sense.
