DG442EEE

Overview

The DG442EEE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels in a 16-pin SSOP package, designed for signal routing applications. The device operates with a maximum on-resistance of 85 ohms and supports dual supply voltages ranging from ±4.5V to ±20V or a single supply from 10V to 30V. Key electrical specifications include a maximum charge injection of 10pC, an off-state leakage current of 500pA, and a channel-to-channel on-resistance matching of 3 ohms. Switching times are specified at 250ns for turn-on and 170ns for turn-off, with a bandwidth exceeding 100MHz.

Feature Summary

Quad SPST configuration providing four independent analog signal paths within a compact surface-mount package.
Low on-resistance characteristic ensuring minimal signal attenuation across the conduction path.
High breakdown voltage capability allowing operation with wide single or dual power supply ranges.
Fast switching speeds suitable for high-frequency data acquisition and multiplexing systems.

Applications

Data acquisition systems requiring multi-channel signal selection
Audio signal routing and switching matrices
Instrumentation front-end multiplexers
Communications equipment signal path control

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as indicated by the suffix. Check for end-of-life notifications or discontinuation notices from the manufacturer. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering. Validate package dimensions against PCB footprint specifications during procurement planning.

Selection Notes

Select this component when quad SPST switching is required with moderate speed and low distortion. Compare on-resistance values against system loss budgets. Verify supply voltage compatibility with existing power rails. Consider package availability and lead times for production scheduling. Evaluate thermal dissipation requirements based on load current and ambient temperature conditions.

Part Context

The DG442 belongs to the Maxim Integrated DG4xx series of improved quad SPST analog switches. This family offers enhanced performance over earlier generations with lower on-resistance and faster switching times. The EE suffix denotes the 16-lead shrink small-outline package variant. Related parts include the DG441 and DG443, which offer similar functionality with different pinouts or performance characteristics.

Replacement Considerations

Direct replacements may include the DG442EY or DG442EY+ variants with identical electrical specifications but different packaging. Cross-reference with DG442EUA for alternative surface-mount options. Verify pinout compatibility before substituting with generic quad SPST switches. Consult manufacturer documentation for updated part number recommendations if the original is discontinued.
