Maxim Integrated Products introduces the MAX4800A/MAX4802A 8-channel, high-voltage, low-charge-injection SPST switches controlled by a fast, 20MHz serial interface. Designed using Maxim's proprietary, BCDMOS process technology, these devices combine high-voltage, bilateral DMOS switches and low-power CMOS logic, thus enabling efficient control of high-voltage analog signals with low-voltage control signals. Additionally, these devices support a wide range of high-voltage supplies, including: VPS /VPS- = 100V/-100V, 185V/-15V, and 40V/-160V. The MAX4802A also integrates 35k%u03A9 bleed resistors to discharge capacitive loads such as piezoelectric transducers, thus saving cost and space by eliminating the need for external bleed resistors. |
