Siliconix Inc. has released an analog switch and multiplexer housed in the 3-by-3mm QFN-12 package and aimed at battery-operated portable applications.

According to the company, the DG2032 dual SPDT analog switch and DG2034 4:1 multiplexer are the first products in a QFN-12 package to combine low 3-ohm on-resistance, low power consumption, and superior switch performance while operating over a wide power supply and analog signal range of 1.8V to 5.5V.

The DG2032 dual SPDT analog switch features a low on-resistance specification of 3 ohms at 2.7V, with wide dynamic performance better than -80dB for both crosstalk and off-isolation at 1MHz. With its switching speeds of 25ns (turn-on) and 13ns (turn-off), high bandwidth and low charge injection, the device is suitable for switching a wide range of audio and video signals.

The DG2034 4:1 analog multiplexer offers an on-resistance of 4 ohms, off-isolation and crosstalk of -55dB at 10MHz, and turn-on time of 25ns. In addition to the QFN-12, the DG2034 is also available in the MSOP-10 package.

Samples and production quantities of the DG2032 and DG2034 are available with lead times of six to eight weeks for larger orders. Pricing for U.S. delivery in 10,000-piece quantities is 60 cents for the DG2032 and 70 cents for the DG2034.
