MP4816A 16-Channel, High-Voltage Analog Switch with Output Bleed Resistors DESCRIPTION FEATURES The MP4816A is a 16-channel, high-voltage, No High-Voltage Supplies Required single-pole, single-throw, SPST, analog switch 16 Channels with integrated output bleed resistors designed Up to 90V Analog Signals for medical ultrasound imaging applications. 12.5 Typical Switch Resistance The MP4816A is designed to multiplex transmit 2.0A Typical Switch Peak Current and receive voltages to and from multiple Off-Isolation of -66dB at 5.0MHz piezoelectric transducers (PZT). Integrated Output Bleed Resistor The output switches are controlled by a 16-bit 80MHz Clock Frequency serial shift register followed by a 16-bit data latch. Available in a TQFP-48 (7mmx7mm) A data out pin (D ) is provided to allow for OUT Package multiple devices to be cascaded together. This APPLICATIONS helps minimize the number of input/output (I/O) control lines. A logic high in the data latch turns Medical Ultrasound Imaging on the corresponding analog switch. A logic low Non-Destructive Testing (NDT) turns off the corresponding analog switch. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality Assurance. The MP4816A does not require any high-voltage MPS and The Future of Analog IC Technology are registered trademarks of Monolithic Power Systems, Inc. supplies. Only two low-voltage supplies are required (3.3V and 10V). The analog switch can block or pass analog voltages up to 90V with peak currents of up to 2.0A. The MP4816A is available in a TQFP-48 (7mmx7mm) package.
