The HV7351 demo board demonstrates Microchip's HV7351 device. HV7351 is an 8-channel programmable high-voltage ultrasound-transmit beamformer. Each channel is capable of swinging up to +/-70V with an active discharge back to 0V. The outputs can source and sink up to 3.0A to achieve fast output rise time and fall times.
There are two complex programmable logic devices (CPLDs) and one serial EEPROM on the HV7351 demo board to provide multiple demo waveform patterns. The output waveforms can be directly displayed using an oscilloscope, by connecting the oscilloscope probe to the test points TX1 - TX8 on the demo board. The dummy load, 330 pF || 2.5K Ohm, is also provided on board for each channel.
