Overview
The DG401DY+ is a dual, high-speed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole/single-throw (SPST) normally open switches in a 16-pin Narrow SO package. The device operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45 Ohms, an on-resistance match between channels of 2 Ohms max, and on-resistance flatness of 3 Ohms max. Switching times are 150ns for turn-on and 100ns for turn-off. Power consumption is 35µW max, with off leakage current less than 5nA at +85°C. Charge injection is 15pC max.
Feature Summary
- Improved on-resistance matching between channels ensures consistent signal path characteristics.
- Guaranteed on-resistance flatness over the entire signal range maintains linearity.
- Low charge injection minimizes transient voltage spikes during switching events.
- Rail-to-rail signal handling capability allows full supply voltage range utilization.
Applications
- Sample-and-Hold Circuits
- Test Equipment
- Guidance and Control Systems
Procurement Notes
Verify the component manufacturer designation, as Analog Devices Inc. and Maxim Integrated are listed interchangeably. Confirm the specific suffix 'DY+' corresponds to the 16-pin Narrow SOIC package and the -40°C to +85°C temperature range. Ensure RoHS compliance documentation matches the '+' suffix requirement for environmental standards.
Selection Notes
Select this component when dual SPST switching is required with low on-resistance variation. The guaranteed 2 Ohm channel-to-channel matching is critical for differential signal paths. Verify that the logic input requirements align with TTL/CMOS compatibility at the intended supply voltage. Consider the 150ns switching speed against system timing constraints.
Part Context
This part belongs to the DG401/DG403/DG405 family of improved dual high-speed analog switches. It serves as a direct upgrade to industry-standard DG401 devices, offering enhanced performance metrics such as lower charge injection and improved leakage characteristics while maintaining pinout compatibility.
Replacement Considerations
DG401DY is a non-RoHS compliant alternative from Renesas Electronics Corporation. Vishay Siliconix offers the DG401DY-T1-E3 as a compatible replacement with similar specifications.
