The DG1408 is a precision analog multiplexer comprising eight single-ended channels. The DG1409 is a dual four single-ended channels analog multiplexer. Built on a new CMOS process, the Vishay Siliconix DG1408 and DG1409 offer low on-resistance of 3.2 Ω. The low and flat resistance over the full signal range provides excellent linearity and low signal distortion. The new CMOS platform also ensures ultra low power dissipation, minimized parasitic capacitance, and low charge injection.
The DG1408 and DG1409 can operate from either a single 4.5 V to 24 V power supply, or from dual ±4.5 V to ±15 V power supplies. The DG1408 connects one of eight inputs to a common output as determined by a 3-bit binary address (A0, A1, A2). The DG1409 connects one of four inputs to a common output for both multiplexers as determined by a 2-bit binary address (A0 and A1).
Break-before-make switching action protects against momentary crosstalk between adjacent channels. The part does not require a VL logic supply, while all digital inputs have 0.8 V and 2 V logic thresholds to ensure low-voltage TTL / CMOS compatibility. Together with the compact package, these make the part a great fit for battery operated systems.
The DG1408 and DG1409 on channel conduct signal equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. An enable (EN) function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices.
The advance performance of low insertion loss and low distortion make the device ideal for signal switching and relay replacement in a wide range of applications.
DG1408 and DG1409 are available in RoHS-compliant, halogen-free QFN16, 4 mm x 4 mm packages.
The main benefits of the DG1408 Series are low insertion loss, low distortion, low power consumption, compact solution, and low charge injection over the full signal range.
Applications for the DG1408 Series include medical and healthcare equipment, data acquisition systems, industrial control and automation, test and measurement equipment, communication systems, battery powered systems, sample and hold circuits, audio and video signal switching, and relay replacement.
