1.1 Introduction

The AMC7908 is a highly integrated power-amplifier monitor and control device capable of temperature, current, and voltage supervision. The AMC7908 bias controller features eight digital-to-analog converters (DAC) with programmable output ranges. The eight gate bias outputs are switched on and off through dedicated control pins.

The AMC7908 supervisor also features a highly accurate multichannel analog-to-digital converter (ADC). The device integrates two high-voltage inputs, two high-side current-sense amplifiers, and an on-chip temperature sensor.

The function integration and wide operating temperature range make the AMC7908 an excellent choice for an all-in-one, bias control circuit for the power amplifiers found in RF communication systems.

This user's guide describes the characteristics, operation, and recommended use cases of the AMC7908EVM. This document provides examples and instructions on how to use the AMC7908EVM board and included software. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the AMC7908EVM. This document also includes schematics, the reference printed circuit board (PCB) layouts, and a complete bill of materials (BOM).
