DG612AEN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG612AEN-T1-E4 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It integrates four independently selectable switches in a 16-lead miniQFN package measuring 1.8 mm x 2.6 mm. The device operates from a single supply of 2.7 V to 12 V or dual supplies of ±2.7 V to ±5 V. Key electrical specifications include a maximum on-resistance of 115 Ω, a typical charge injection of 1 pC, and an off-leakage current below 0.25 nA at 85 °C. Dynamic performance features a turn-on time of 27 ns, a turn-off time of 16 ns, and a 3 dB bandwidth of 720 MHz. The component supports logic levels compatible with 2.5 V CMOS/TTL standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. The 'E4' suffix indicates RoHS compliance, while 'T1' denotes tape and reel packaging. Confirm that the miniQFN-16 leadless package requirements align with your PCB assembly capabilities, as manual soldering is not recommended for this component.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG612A variant specifically when normally open switch configuration is required, distinguishing it from the DG611A (normally closed) and DG613A (mixed) models. Ensure the application voltage does not exceed the 12 V single-supply limit. Consider the miniQFN package dimensions if space constraints are critical, noting that thermal derating applies above 70 °C.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG611A/DG612A/DG613A family, which improves upon the industry-standard DG611 series. The family utilizes a hybrid technology combining CMOS control logic with DMOS power switches. This specific part number represents the DG612A variant housed in a compact miniQFN-16 package, designed for high-density surface-mount applications requiring fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers: DG612AEY-T1-E3 (Narrow SOIC), DG612AEQ-T1-E3 (TSSOP). These variants share identical electrical characteristics but differ in physical package footprint and pinout compatibility.
