DG611AEQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG611AEQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates from a single supply of 2.7 V to 12 V or dual supplies of ±2.7 V to ±5 V. The device features four independently selectable switches with a maximum on-resistance of 115 Ω at room temperature and 160 Ω across the full temperature range. It offers a typical charge injection of 1 pC, off-isolation of -62 dB at 10 MHz, and a 3 dB bandwidth of 720 MHz. Switching times are specified as 27 ns turn-on and 16 ns turn-off at ±5 V. The component is housed in a 16-lead TSSOP package and supports an operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status and halogen-free certification requirements prior to procurement. Ensure the selected variant matches the required logic polarity and voltage specifications for the target application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low charge injection and high bandwidth are critical for signal fidelity. Verify that the required on-resistance flatness and leakage current limits fall within the specified ranges for the intended supply voltage. Consider the thermal dissipation capabilities of the TSSOP-16 package relative to the expected power load and ambient temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG611A series, which includes variants with different switch states such as normally open or mixed configurations. The 'EQ' suffix denotes the 16-lead TSSOP package, while 'E3' indicates lead-free termination compliant with RoHS directives. This series serves as an improved performance alternative to the legacy DG611 family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include DG611AEY-T1-E3 for narrow SOIC packaging. Other family members like DG612AEQ-T1-E3 offer different switch states. Verify pin compatibility and electrical parameters before substituting.
