EV4835A-RD-00A 180V, 32-Channel Analog Switch Evaluation Board
The EV4835A-RD-00A is an evaluation board for the MP4835A, a high-voltage, 32-channel analog switch. The MP4835A is designed for medical ultrasound applications. It can also be used for non-destructive test (NDT) applications, as it is 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 MP4835A has a resistor connected to ground on the output pin (SWOUT). This helps ensure that a significant DC voltage does not build up across the PZT element. The switches can be turned on/off via a serial 32-bit shift register. The serial control interface helps minimize the number of I/O connections.
