MCP4822

MCP4822 is a dual channel 12-bit Digital-to-Analog converter (DAC) with internal voltage reference. This device offers high accuracy and low power consumption, and is available in various packages. Communication with the device is accomplished via a simple serial interface using SPI protocols. The MCP4822 device is a part of the MCP4802/MCP4812/MCP4822 product family, which are dual channel 8-bit/10-bit/12-bit DACs with internal voltage reference (VREF). These devices provide very high accuracy and low noise performance, and are suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications. The low power consumption and small package options make these devices very attractive for many portable and battery-powered applications. If one output is needed then the MCP4801/4811/4821 single channel product family can be used.

Designing and Building a PIC32 Video Game

“Two students at Cornell University have developed a video game based on a PIC32 Microcontroller using a new version of the boids algorithm. We created a multiplayer video game that runs on a PIC32 microcontroller (Figure 1). Our game simulates …

Build a Self-Correcting LED Clock

“MCU-Driven Art In North America, most radio-controlled clocks use WWVB’s transmissions to set the correct time. WWVB is a Colorado-based time signal radio station. Learn how these two Cornell students designed and built a prototype of a Digital …

Multi-Key Electronic Flute

“Sensors and Synthesis Musical instruments such as the piano allow musicians to play in different keys on a single instrument. In contrast, bamboo flutes are designed for only one key. This means flute players must own a different flute for …

Web Controlled Multifunctional Car

“In our final project, we have built a multi-functional car controlled by a web application on the PC, which allows users to drive the car as well as play music from the interface on the website. All the requests from …

Diy Step/Dir Laser Galvo Controller

“Hi, in this Instructable, I want to show you how you can build your own step / dir interface for ILDA standard galvo laser scanners. As you might know I am also the inventor of the “DIY-SLS-3D-Printer” and the …

Programmable Sequenced Wavetable Synthesizer

“For our final project, we created a wavetable synthesizer capable of playing back short user-programmable sequences with a large range of timbres. We decided to create a fun, easy-to-use wavetable synthesizer with just enough parameters to offer a large sonic …

USB Audio Streamer A Microchip PIC based USB sound card

“The sound card runs at a sample rate of 48KHz, 32KHz or 24KHz selectable by the OS with 12 bits per sample. The quality approaches commercial grade as the sample rate is higher then CDs. 44.1KHz was not implemented …
