MP4816AGFP

Analog Switches - Special Purpose Overview

The MP4816AGFP is a 16-channel high-voltage analog switch manufactured by Monolithic Power Systems Inc. It features single-pole single-throw (SPST) architecture with integrated output bleed resistors, designed for medical ultrasound imaging applications. The device multiplexes transmit and receive voltages to piezoelectric transducers without requiring high-voltage supplies, operating on 3.3V and 10V logic levels. It supports analog signals up to ±90V with peak currents of ±2.0A. Key electrical parameters include a typical switch resistance of 12.5Ω, off-isolation of -60dB at 5.0MHz, and an 80MHz clock frequency. The component is housed in a TQFP-48 package measuring 7mm x 7mm.

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer part number against official Monolithic Power Systems documentation to ensure authenticity. Confirm that the suffix 'GFP' corresponds to the TQFP-48 package variant. Request original datasheets and material safety data sheets from authorized distributors to validate compliance with industry standards before integration into production designs.

Analog Switches - Special Purpose Selection Notes

Select this component when designing ultrasound front-ends requiring high-voltage switching without external HV supply rails. Ensure the design accommodates the ±90V signal range and ±2.0A peak current capabilities. Verify that the 3.3V/10V logic interface aligns with the system's microcontroller or driver outputs. Consider the 12.5Ω on-resistance impact on signal integrity for high-frequency applications.

Analog Switches - Special Purpose Part Context

This device belongs to Monolithic Power Systems' portfolio of specialized analog switches tailored for medical imaging. It addresses the specific need for high-voltage multiplexing in ultrasound arrays where space and power efficiency are critical. The integration of bleed resistors simplifies board layout compared to discrete solutions.

Analog Switches - Special Purpose Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided reference materials. Evaluate alternative 16-channel high-voltage analog switches only if they match the ±90V rating, SPST configuration, and TQFP-48 footprint while verifying pin compatibility.
