Audio Switches Deliver High Performance in Space Constrained Designs
As portable electronic products such as mobile handsets, MP3 players, and PDAs push increasing functionality and performance into shrinking form factors, each IC within the design must shrink accordingly. These latest low voltage switches in tiny packages address this concern by delivering leading edge performance for audio, data, and level translation applications. The ADG772 universal USB 2.0/USB 1.1 switch offers high bandwidth for USB 2.0, as well as the required signal range for the older USB 1.1 standard. The new series of ADG85x audio switches offers the industry's smallest <1 Ω audio switches with fully packaged units occupying only 1.3 mm × 1.6 mm board area. The ADG3304 series level translators offer the widest level translation range (1.15 V to 5.5 V) in the industry for maximum design flexibility. A typical handset may use these parts to switch between speaker and hands-free audio (ADG852 series) or between the multiplex USB and headset audio (ADG772 series). The ADG3304 series may be used to and level translate between the chipset and ASIC. MP3 players may use the ADG852 series to switch between standard and hands-free audio, or the ADG772 series may be used to multiplex data and audio to the I/O. Many other audio and data applications can use a combination of these switches to achieve optimal product performance.
Improving Battery Life with Intelligent Lighting Solutions Power dissipation for backlight and keyboard scan functions consumes approximately one-third of the battery in today's advanced mobile devices. Conventional designs require waking the handset's processor to activate most lighting and key scan features, significantly reducing battery life. With the introduction of ADI's autonomous adaptive light management solution, lighting control, as well as key scan functions, can be performed independent of the processor, dramatically reducing system power consumption. In addition to enabling significant power savings, the ADP5520 and ADP5588 utilize ADI's proprietary ambient lighting technology to offer users incredibly responsive and smooth transitions between lighting schemes as they move through lighting environments. Operating independent of the processor also reduces the number of lines running across the hinge—down to three from 10 or more in a typical application. In addition to the ADP5520 and ADP5588, ADI offers a variety of other innovative and affordable power IC solutions for consumer applications as indicated in the table below.
