SANTA CLARA, Calif.--(BUSINESS WIRE)--March 22, 2004

Siliconix incorporated (NASDAQ: SILI), an 80.4%-owned subsidiary of Vishay Intertechnology Inc. (NYSE: VSH), today announced the release of a new analog switch and multiplexer packaged in the 3-mm by 3-mm QFN-12 package and aimed at battery-operated portable applications.

The new DG2032 dual SPDT analog switch and DG2034 4:1 multiplexer are the first products in the QFN-12 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 1.8-V to 5.5-V.

Unlike other small analog switches aimed at audio only, these parts cater to the needs of both audio and higher-speed analog signal switching for port sharing/extension, data acquisition, PC Cards (PCMCIA), audio/video signal routing, speaker/headset switching, and similar applications in end products such as cell phones, digital cameras, PDAs, MP3 players, and handheld test and health care equipment. While retaining the desired switch performance at very low power consumption, these devices boast high switching speeds and outstanding linearity over the full supply and signal voltage range.

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

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