Status: In Production
HV2809 is a low harmonic distortion, 32-channel, high voltage analog switch integrated circuit (IC), designed for use in medical ultrasound imaging systems as a probe selection relay replacement. It serves as a 16PDT (16-pole, double throw) high voltage analog switch array. The enable function allows the parts to be configured as either a 2:1 or 4:1 multiplexer/demultiplexer. The HV2809 is a very fast transducer multiplexer that consumes minimal power and emits no audible noise. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V. The HV2809 comes in an 8.0mm x 8.0mm x 1.0mm, 56-Lead QFN package. Compared to an electromechanical relay, it not only saves considerable PCB area, but also saves on the PCB assembled height.
