NEW DEVICES TARGET 1.8- TO 5.5-V HANDHELD ELECTRONICS APPLICATIONS
22 March 2004 - Vishay Electronic

Siliconix incorporated, an 80.4%-owned subsidiary of Vishay Intertechnology, Inc, 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-Ω 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, 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 Ω 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 Ω 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.

Providing good value for cost sensitive applications, the new products are the latest in a growing family of low-voltage, high-density CMOS analog switching devices from Vishay Siliconix that give designers a wider choice of surface-mount analog switching options for battery-powered, portable designs.

Samples and production quantities of the DG2032 and DG2034 are available now with lead times of six to eight weeks for larger orders.
