General Description
The HV2808 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-pole double-throw (PDT) high-voltage analog switch array. The device is a very fast transducer multiplexer that consumes minimal power and emits no audible noise.
This device bines high-voltage bilateral DMOS switches and low-power CMOS logic to provide efficient control of high-voltage analog signals. The HV2808 is suitable...
