DG441DY

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.

Feature Summary

Improved on-resistance matching between channels for consistent signal path performance
Guaranteed on-resistance flatness over the entire specified analog signal range
Enhanced electrostatic discharge protection capability exceeding standard industrial requirements
Low off-leakage current characteristics maintained across the full operating temperature range

Applications

Sample-and-hold circuits requiring precise signal gating
Communication systems utilizing analog signal routing
Test equipment involving multiplexed data acquisition
Battery-operated systems prioritizing low power consumption

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.

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.

Part Context

This device belongs to the DG441/DG442 family of improved analog switches. It serves as a direct replacement for legacy industry-standard parts while offering enhanced electrical specifications. The design retains pin compatibility but improves upon previous generation leakage and matching metrics.
