General Description
The Supertex 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...
