DG2728DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2728DN-T1-E4 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.6 V to 4.3 V and supports negative signal swings down to V+ - 4.3 V. The device features a typical on-resistance of 0.65 Ω at 2.7 V, with a maximum of 1.0 Ω at room temperature. It provides a -3 dB bandwidth of up to 252 MHz and exhibits a total harmonic distortion of 0.006%. The component is housed in a miniQFN-8L package measuring 1.4 mm x 1.4 mm x 0.55 mm and functions within an extended temperature range of -40 °C to +85 °C.

Ensure that the requested part number matches the exact electrical specifications required for the design. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when board space is limited due to its compact miniQFN-8L footprint. It is suitable for battery-powered designs requiring low quiescent current and wide operating voltage ranges. Consider the negative swing capability if interfacing with signals that extend below the positive rail.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2727/DG2728/DG2729 family of low-voltage analog switches. While functionally similar regarding resistance and speed, the DG2728 differs from the DG2727 and DG2729 in its internal pinout configuration and logic sense. Designers must consult the functional block diagram to ensure correct signal routing compared to other variants in the series.
