DG301AC/D

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301AC/D is a single-channel SPDT analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features a 50 Ohm maximum on-resistance and operates with dual supply voltages ranging from ±5V to ±18V. The device exhibits a charge injection of 12pC, off-state leakage current of 5nA, and switching times of 300ns (Ton) and 250ns (Toff). Designed for die-level integration, it supports signal routing in applications requiring low distortion and high isolation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package type as the model designation indicates a die form factor rather than a standard surface-mount package. Confirm that the manufacturing status aligns with project requirements, noting potential obsolescence or limited availability. Ensure design compatibility with bare-die handling processes and verify RoHS compliance documentation for the specific production lot before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single SPDT switch is required within a custom integrated circuit design or specialized packaging solution. Consider the 50 Ohm on-resistance and ±18V supply range against system voltage constraints. Evaluate the 12pC charge injection and 5nA leakage specifications against signal precision requirements. Ensure the application supports direct die integration or appropriate substrate mounting techniques.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG301AC/D belongs to the DG300 series of TTL-compatible CMOS analog switches. This series provides robust switching capabilities for various analog signal paths. The 'D' suffix typically denotes a die configuration, distinguishing it from packaged variants like the DG301ACWE+. Understanding the series context helps in evaluating pinout compatibility and electrical characteristics relative to other members of the family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

For packaged equivalents, consider the DG301ACWE+ which offers identical electrical specifications in a 16-SOIC package. Verify functional compatibility regarding pin assignments and thermal management requirements when transitioning from die to packaged solutions.
