Microchip Technology HV2808
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.| Part No. | HV2808 |

This device combines high-voltage bilateral DMOS switches and low-power CMOS logic to provide efficient control of high-voltage analog signals. The HV2808 is suitable for various combinations of high-voltage supplies, such as VPP/VNN: +40V/–160V, +100V/–100V and +160V/–40V. Moreover, the HV2808 comes in an 8 mm x 8 mm x 1 mm 56-lead VQFN package. Compared to an electromechanical relay, it does not only save considerable PCB area but also PCB-assembled height. Package Type 56-lead VQFN (Top view) 56 1 See Table 2-1 for pin inform...
