New Vishay Siliconix Dual SPDT and Dual SPST Analog Switches Target Portable Systems With On-Resistance Down to 2.5 W and 3-dB Bandwidth Up to 360 MHz
MALVERN, Pa. — October 17, 2005 — Vishay Intertechnology, Inc. (NYSE: VSH), today released a family of new dual SPDT and dual SPST analog switches designed for audio, video, and data stream applications. Offering low on-resistance and high bandwidth in the space-saving MICRO FOOT® package through the full voltage range of 1.8 V to 5.5 V, the six new switches are aimed at end products including cell phones, PDAs, media players, and notebook computers.
The DG35xx family of analog switches released today is built on a submicron high-density process for low power consumption and high performance at low voltage levels. The six switches are offered in MICRO FOOT packaging with lead (Pb)-free bump terminations in 3x3 and 4x3 configurations. All six analog switches are 1.6-V logic compatible within their full operational voltage range. This combination of MICRO FOOT packaging and low voltage logic makes the DG35xx family of switches well suited for low voltage portable devices.
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 suitable for video and data stream applications. Their low on-resistance, 1-ohm flatness, and 0.2-ohm matching — 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.
New Dual SPDT and SPST Analog Switches: Summary Table
|Devices||Configuration||rDS(on) @ 2.7 V (Ω)||3-dB Bandwidth (MHz)||Latch-Up Current (mA)||MICRO FOOT® Bump Array|
|Dual SPDT||2.5||300||200||4x3 (10 bumps)
2.0 mm x 1.5 mm x 0.7 mm
|Dual SPST||4.0||360||300||3x3 (8 bumps)
1.5 mm x 1.5 mm x 0.7 mm
The DG35xx family offers a full rail-to-rail signal swing range and ESD protection over 2 kV according to method 3015.7. Their operating temperature range is -40 °C to +85 °C.
Samples and production quantities of the new analog switches are available now, with lead times of six to eight weeks for larger orders.
