DG442ETE+

Overview

The DG442ETE+ is a quad, single-pole/single-throw (SPST) analog switch from the DG441/DG442 series. It features four normally open switches with an on-resistance of 85 Ω maximum and on-resistance matching 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 turn-on time of 250 ns maximum, turn-off time of 170 ns maximum, charge injection of 10 pC maximum, and off-leakage current less than 5 nA at +85°C. It is housed in a 16-pin Thin QFN package with an exposed pad.

Feature Summary

Quad SPST configuration with four independently controlled normally open switches
Guaranteed low on-resistance flatness over the signal range for consistent performance
Low power consumption suitable for battery-operated systems
TTL/CMOS logic compatible control inputs

Applications

Sample-and-hold circuits
Audio-signal routing
Test equipment
Communication systems

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the ordering suffix matches the required lead-free status and package type. Confirm that the thermal characteristics align with the application's heat dissipation requirements before finalizing procurement.

Selection Notes

Select this component when a quad SPST analog switch with low on-resistance and high channel matching is required. Consider the Thin QFN package for space-constrained designs. Verify that the operating voltage range meets the system's single or dual supply needs. Check the temperature range specification to ensure suitability for the intended environmental conditions.

Part Context

The DG442ETE+ belongs to the DG441/DG442 family of improved analog switches. It shares the same pinout and core functionality as the DG441 but differs in switch state (normally open vs. normally closed). The ETE suffix indicates the Thin QFN-EP package and extended temperature range (-40°C to +85°C). This part is a redesign offering better performance metrics compared to legacy versions.
