austriamicrosystems Expands Family of High-Speed Analog Signal Switches

Introducing the AS1751/AS1752/AS1753 high performance analog quad switches designed for high-speed switching of audio, video and data signals in portable devices like mobile phones, MP3, CD/DVD and video players, digital cameras, PDAs and other handheld devices

RALEIGH, N.C. (October 7, 2005) - austriamicrosystems announced today the availability of another family of high-performance analog switches. These high-speed, low-voltage, quad, single-pole/single-throw (SPST) analog switches offer significant performance improvements over existing products. Typical switching time has been improved by over 40% while maintaining superior on-resistance (Ron), flatness and channel matching. Through the improved bandwidth of 130MHz, the devices are ideal for video and high-speed data signals. The wide supply voltage range from 1.6V to 3.6V supports a broad range of designs. All digital logic inputs are 1.8V CMOS compatible.

The combination of very low power consumption, low Ron and fast switching speed makes these devices ideal for portable battery-powered applications and allows for switching of currents up to 250mA. The excellent power routing performance enabled by the low Ron of only 0.9 Ohm makes these high-performance switches a perfect match for low-Ohm speakers and headsets.

The high-performance analog quad switches are available as normally open (AS1751), normally closed (AS1752) and a combination of open and closed (AS1753).

The AS1751, AS1752 and AS1753 are available in a 16-pin QFN or 14-pin TSSOP package and are drop-in replacements for MAX4751, MAX4752 and MAX4753. For product specific information and to request samples please go to
