EVAL-ADL8113 no-OS Example Project

See projects/eval-adl8113 (doxygen) for the Doxygen documentation.

The ADL8113 is a wideband, digitally controlled variable gain amplifier (DVGA) that operates from 10 MHz to 14 GHz. The device provides precise gain control through a parallel digital interface, through VA and VB pins. This project demonstrates basic control of the ADL8113 using GPIO pins on the MAX32655FTHR platform.

Hardware Specifications

Power Supply Requirements

The ADL8113 requires proper supply voltages for operation. For this project, the digital control interface is powered from the MAX32655FTHR 3.3V rail.

Basic Example

This is a simple example that:

Initializes the ADL8113
Cycles through every mode of the chip, through button 1 on MAX32655FTHR, using a state machine
Demonstrates gain control and switch control via GPIO pins
