Analog switches crank out bandwidth

Malvern, Pa. — Vishay Intertechnology, Inc.'s dual, single-pole, double throw and dual, single-pole, single throw analog switches are said to offer low on-resistance (2.5 Ohms) and high 3-dB bandwidth (up to 360 MHz) in a tiny package.

Through the full voltage range of 1.8 V to 5.5 V, the six new switches are aimed at portable applications including cell phones, PDAs, media players, and notebook computers.

The switches are offered in the company's Micro Foot packaging with lead (Pb)-free bump terminations in 3mm x 3mm, and 4mm x 3mm-configurations. All of the switches are 1.6-V logic compatible within their full operational voltage range.

The dual, spdt DG3516/17 switches feature a 300-MHz 3-dB bandwidth, while the dual, spst DG3537/38/39/40 switches feature a 360-MHz 3-dB bandwidth for video and data-stream applications.

Their low on-resistance, 1-Ω flatness, and 0.2-Ω matching — which is key for achieving low distortion, signal fidelity, and high linearity — provide excellent performance for audio and video applications such as speaker switching, port sharing, and USB switching, according to Vishay.

The DG35xx family offers a full rail-to-rail signal swing range and electrostatic discharge (ESD) protection over 2 kV. Their operating temperature range is -40°C to +85°C.

The analog switches are available now, with lead times of six to eight weeks for larger orders. Pricing is 65 cents each for U.S. delivery in 1,000-piece quantities. Click here for the DG3516/DG3517 data sheets. Click here for the DG3537/DG3538/DG3539/DG3540 data sheet.
