DG401DY+

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
