DG441DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441DY+ is a quad, single-pole/single-throw (SPST) analog switch fabricated using a silicon-gate process. It features four normally closed switches with an on-resistance of 85 Ω maximum and an on-resistance match of 4 Ω maximum between channels. 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 250 ns maximum, a turn-off time of 120 ns maximum, and charge injection of 10 pC maximum. It provides rail-to-rail signal handling, low power consumption of 1.65 mW maximum, and an ESD tolerance of 2000V minimum per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and package type. The plus symbol indicates compliance with environmental directives. Confirm that the narrow SOIC package matches the intended PCB footprint. Ensure the temperature grade aligns with the operational environment requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed configuration is required for the analog switching application. Compare the 85 ohm on-resistance against system loss budgets. Verify that the bipolar supply voltage range accommodates the available power rails. Consider the 4 ohm channel matching if signal integrity across multiple paths is critical.
