EV4864A-BD-00A 180V, 64-Channel Analog Switch Evaluation Board
The EV4864A-BD-00A is an evaluation board designed to demonstrate the capabilities of the MP4864A, a high-voltage, 64-channel analog switch. The MP4864A is designed for medical ultrasound applications. It can also be used for non-destructive test (NDT) applications, which are very similar to medical ultrasound.
The high-voltage analog switches are used to multiplex the transmitter and receiver circuitries to different piezoelectric transducer (PZT) elements. The MP4864A has a resistor to ground on the output pins (SWout). This ensures that a significant DC voltage does not build up across the PZT element. The switches can be turned on/off via a serial 64-bit shift register. The serial control interface helps minimize the number of I/O connections.
