DG406DN+T

Overview

The DG406DN+T is a high-performance CMOS analog multiplexer manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 28-PLCC surface-mount package. It features a 1x16:1 configuration with 16 independent channels. The device operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 175 Ohms, a propagation delay of 300 ns, and a maximum power dissipation of 842 mW. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• CMOS technology ensures low power consumption and high input impedance for signal integrity.
• High isolation and low charge injection minimize signal distortion during switching operations.
• Wide single and dual supply voltage compatibility allows flexibility in various system architectures.

Applications

• Data acquisition systems requiring multi-channel signal selection.
• Industrial process control instrumentation.
• Medical equipment signal routing.

Procurement Notes

Verify the specific suffix 'T' against official manufacturer documentation to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Confirm RoHS compliance details directly with the supplier. Ensure the component source is an authorized distributor to guarantee authenticity and traceability for critical applications.

Selection Notes

Select this component when a 16-channel multiplexer with moderate speed and wide voltage range is required. Compare on-resistance values against application requirements to ensure signal accuracy. Verify that the PLCC-28 footprint fits the PCB layout constraints. Consider thermal dissipation limits if multiple channels are active simultaneously within the specified temperature range.

Part Context

This part belongs to the DG406 series of improved CMOS analog switches. It serves as a digital-to-analog interface component, allowing multiple input signals to be routed to a single output line. The series is designed for applications demanding reliable switching performance in industrial and commercial environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as DG406EUI+, which offers similar functionality in a TSSOP package. Verify electrical parameters match before substitution. Consult the manufacturer's obsolescence notices for any discontinued variants.
