General Description
The HV2809 is a 32-channel, low harmonic distortion, high-voltage analog switch integrated circuit designed for medical ultrasound imaging systems as a probe selection relay replacement. It serves as a 16 PDT (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.
