Alpha & Omega Semi Introduces Family of Low Voltage and Low On-Resistance Analog Switches

October 13, 2009 by Jeff Shepard

Alpha & Omega Semiconductor, Inc. (AOS) announced the release of a family of eight low voltage analog switches. The new products have an operating voltage range from 1.65 to 4.3V and are available in several single and dual configurations. The new analog switches are optimized for the switching of audio and data I/O lines in portable consumer applications.

The AOZ62xx family of dual analog switches offers very low on-resistance and on-resistance flatness. The AOZ6232, for example, is rated at a very low 0.25Ω at 2.7V with a 0.15Ω flatness rating. These features provide a solution with low insertion loss and low total harmonic distortion, which preserves overall signal integrity and allows for seamless multiplexing of various audio and data sources. The six AOZ62xx products are housed in very small footprint QFN package options, making them optimal for portable battery operated applications.

The AOZ61xx single analog switches are well suited for general purpose data switching applications. The AOZ6135 is housed in an industry standard SC70 package and features on-resistance of 0.6Ω at 4.5V. The AOZ6115 is housed in the SOT23-5L package and features a very low capacitance of 18pF, and a low charge injection of 1pC (Vcc = 2.7 to 3.6V). These ratings allow for decreased signal distortion, making the AOZ6115 well suited for inline data switching in high speed applications.

"We are pleased with the market acceptance of our new low on-resistance analog switch product family," said Wayne Eng, Marketing Director for AOS’ TVS and Analog Switch Products. "Our new analog switch products provide a seamless solution for the switching and multiplexing of different input streams with multiple external touch points, like between a speaker and headset for audio, or like connecting an external USB signal to the data I/O lines."
