Switch cuts resistance for multimedia
handsets
The ADG849 high-performance analogue switch is optimised to provide best-of-class audio switch quality in handset and portable multimedia designs.
The ADG849 high-performance analogue switch is optimised to provide best-of-class audio switch quality in handset and portable multimedia designs that require higher voltage supplies to support media-rich features, such as musical ringing tones and colour screens The ADG849 is the industry's first SPDT (single-pole, double-throw) switch in an SC70 package to feature sub-1ohm resistance at 5.5V supply

Analog Devices is sampling two new low-cost ADSP-219x models - the ADSP-2195 and ADSP-2196 - expanding the ADSP-21xx family of code compatible digital signal processors.
The ADG849 minimises distortion on audio signals up to 5.5V, making it an ideal solution for new handset designs that require higher voltage supplies to support polyphonic (musical) ringing tones, and other multimedia features, such as colour screens and graphics.
The switch reduces on resistance to less than 1ohm, with total harmonic distortion of 0.02% at 25C.
It has a wide operating range of +1.8 to 5.5V, providing significant performance advantages over other switching solutions in SC70 packaging.
The ADG849 is ideally suited for space-constrained applications that require minimal distortion through the switch, including cellphones, PDAs, battery-powered systems, audio and video signal routing, modems, PCMCIA cards, hard drives and relay replacement.
The ADG849 is housed in a 6-lead SC70 package.
Pricing per unit in 1000-piece quantities is $0.94.
Samples are available now, with full production scheduled for early 2004.
