RALEIGH, N.C. (September 13, 2005) - austriamicrosystems announced today the availability of its first family of high performance analog switches. These high-speed, low-voltage, dual, single-pole/single-throw (SPST) analog switches offer significant performance improvements over existing products. Switching time has been improved by over 40% while maintaining superior low 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, 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 0.8 Ohms makes these high performance switches a perfect match for low-Ohm speakers and headsets.

The first series of high performance analog switches is available as two normally open (AS1741), two normally closed (AS1742) and a combination of one open and one closed switch (AS1743).
