DG509AEWE+

Overview

The DG509AEWE+ is a monolithic CMOS analog multiplexer featuring four differential channels (2-of-8 configuration) in a 16-pin Wide SO package. It operates on dual supplies ranging from ±4.5V to ±18V, supporting analog signals up to ±15V. The device guarantees break-before-make switching and latchup-proof construction. Electrical characteristics at ±15V include a maximum drain-source on-resistance of 450Ω, source off-leakage current of 5nA, and drain off-leakage current of 5nA. Dynamic performance specifies a transition time of 1.0µs, enable turn-on time of 1.5µs, and off-isolation of 68dB at 500kHz.

Feature Summary

Differential 4-channel (2-of-8) multiplexing architecture
Guaranteed break-before-make switching action
Latchup-proof construction for robust operation
TTL and CMOS compatible logic and enable inputs

Applications

Control Systems
Data Logging Systems
Aircraft Heads-Up Displays
Data-Acquisition Systems
Signal Routing

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the Wide SO package dimensions match the target PCB footprint. Confirm RoHS compliance status as indicated by the plus suffix. Validate that the operating temperature range meets the specific environmental requirements of the intended application before finalizing procurement.

Selection Notes

Select this part when differential signal routing is required within a single multiplexer package. The DG509AEWE+ serves as an improved second source with faster enable times and lower leakage compared to legacy versions. Verify supply voltage constraints, as minimum operation requires ±4.5V. Consider the 16-pin Wide SO package size relative to available board space and thermal dissipation needs for the specific system design.

Part Context

This component belongs to the DG508A/DG509A family of monolithic CMOS analog multiplexers manufactured by Maxim Integrated, now part of Analog Devices. The DG509A specifically provides differential channel capabilities, distinguishing it from the single-ended DG508A. Both devices are designed as plug-in upgrades for industry-standard equivalents, offering enhanced performance metrics such as reduced power consumption and improved switching speeds.
