64 Channel High Voltage Analog Switch 10x10 BGA-144
off-isolation
Good Off-Isolation -66dB at 5.0 MHz

The MPS proprietary high voltage analog switches are designed to multiplex the transmit and receive signals to and from multiple piezoelectric transducers in a medical ultrasound imaging system without the need of any high voltage positive or negative supplies. During the transmit cycle, it can block or pass transmit signals of up to ±90V. During the receive cycle, it behaves as a low noise 12.5 Ω resistor or block with an off-isolation of -66dB at 5.0MHz. Eliminating the need for high voltage positive and negative supplies will provide designers a simple and easy solution for the multiplexing.
