austriamicrosystems recently announced the availability of its first family of high performance analog switches that promise significant performance improvements over existing products.

According to the press release, the switching time of these high-speed, low voltage, dual, single-pole/single-throw (SPST) analog switches has been improved by over 40 percent while maintaining superior R on flatness and channel matching. Through the improved bandwidth of 130MHz, the devices are suitable for video and high-speed data signals. The wide supply voltage range from 1.6V to 3.6V supports a broad range of designs, and all digital logic inputs are 1.8V CMOS compatible.

austriamicro said that the combination of very low power consumption, low on-resistance (R on) 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 R on of only 0.8 ohms makes these high performance switches a perfect match for low Ohm speakers and headsets, added the company.

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).
