AS175x: 0.9 ohm high speed analog signal switch series[Copy link]
On November 10, austriamicrosystems introduced a new series of high-performance analog switches, the AS1751, AS1752 and AS1753. These high-speed, low-voltage, square, single-pole single-throw (SPST) analog switches outperform similar products on the market today. It improves typical switching time by more than 40% while maintaining excellent on-resistance (Ron) flatness and channel matching. The improved device with a bandwidth of 130MHz is an ideal solution for video and high-speed data signals. Its supply voltage range is between 1.6V and 3.6V, supporting a wide range of designs. All digital logic inputs can meet the requirements of 1.8V CMOS. The AS1751, AS1752 and AS1753 high-performance analog switches are ideal solutions for audio, video and data signal applications, suitable for portable devices such as mobile phones, MP3, CD/DVD and handheld devices such as video players, digital cameras, PDAs, etc.
Low power consumption, low on-resistance (Ron) and high-speed switching speed make these devices ideal for battery-driven portable devices. Switching currents up to 250mA, combined with best-in-class power routing performance and a low on-resistance (Ron) of only 0.9Ω, make these high-performance switches ideal for low-resistance speakers and headphones.
This series of high-performance analog square switches comes in three models: a normally open switch (AS1751), a normally closed switch (AS1752), and a switch that combines open and closed functions (AS1743). The AS1751, AS1752, and AS1753 are available in 16-pin QFN or 14-pin TSSOP packages and are drop-in replacements for the MAX4751, MAX4752, and MAX4753.
