General Description
The Supertex 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 more than 3.0A to achieve fast output rise and fall times. The active discharge is also capable of sourcing and sinking 3.0A for a fast return to ground. The topology of the HV7351 will significantly reduce the number of I/O logic control lines needed.
Each pulser has four associated 64-bit shift registers for storing pre-determined transmit patterns and a 10-bit delay counter for controlling the transmit time. One of four...
