DG401DJ+

Overview

The DG401DJ+ is a dual, high-speed analog switch in a 16-pin Plastic DIP package. It features two single-pole/single-throw (SPST) normally open switches with a maximum on-resistance of 45 Ohms and guaranteed matching of 2 Ohms. The device operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. Key electrical parameters include a maximum turn-on time of 150ns, turn-off time of 100ns, charge injection of 15pC, and off-leakage current less than 5nA at +85°C. Power consumption is limited to 35µW.

Feature Summary

• Guaranteed low on-resistance matching between channels for precision signal switching
• Rail-to-rail signal handling capability over the full analog range
• TTL and CMOS logic compatible inputs for simple interfacing
• Break-before-make switching action prevents signal shorting

Applications

• Sample-and-Hold Circuits
• Test Equipment
• Guidance and Control Systems
• Audio Signal Routing
• Battery-Operated Systems

Procurement Notes

Verify the ordering suffix matches the required temperature range and package type. The 'J' suffix indicates a Plastic DIP package with an operating temperature range of -40°C to +85°C. Confirm RoHS compliance status as specified in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when dual SPST switching is required with high voltage tolerance up to 44V. Ensure the application demands low power consumption suitable for battery operation. Verify that the 45 Ohm maximum on-resistance meets the circuit's signal integrity requirements compared to lower resistance alternatives.

Part Context

This part belongs to the DG401/DG403/DG405 series of improved dual high-speed analog switches. The DG401 variant specifically provides two SPST switches, distinguishing it from the DG403 (SPDT) and DG405 (DPST/SPDT) configurations within the same family.
