Analog and Power for AM35x

Introduction

This page serves as a repository of Complimentary Analog and Power Devices that can be paired with the AM35x (AM3517 and AM3505) SoC devices when integrating the device into a system. The Complementary Products listed here serve a wide range of functions such as:

• Providing basic support functions for the SoC (power, clocking, etc.)
• Expanding the interface options beyond the on-chip peripherals
• Creating the link between the digital domains on the SoC to the system's analog/physical domains

The Complementary Analog & Power Products are organized into functional categories, with the goal of showing several options and their respective benefits.
