Description
Number of channels: 4
Digital-to-analog Converter: MCP4728
Bit resolution: 12
Maximum data rate: 3.4 Mbps
Rail-to-rail operational amplifier
The Aptinex 4 channel DAC Module DA4C010BI I2C Digital to analog 0 10V MCP4728 is an ideal solution for data acquisition applications. This module uses I2C as its communication protocol, making it compatible with a wide range of microcontrollers and hardware platforms without much hassle. It possesses an improved capability compared to its single-channel predecessor DA1C010BI, allowing it to control four channels simultaneously.

The MCP4728 I2C DAC IC with an on board power boost and rail to rail signal amplifier is used to convert the 0-5V output of the DAC to a 0-10V DAC signal with 12-bit resolution and 1% accuracy. It is also possible to share two DACs of this type on the same bus, and the I2C address can be changed by plugging or removing the I2C address jumper. If more than two of these DAC modules are needed, it is advised to use an I2C multiplexer controller to connect multiple of these DAC modules with one I2C master device.
Three modes of operation are supported: standard (100kbps), fast (400kbps), and high speed (3.4Mbps). This module is compatible with Raspberry Pi, Arduino, Onion Omega, Beaglebone, Windows, and Particle Photon.
If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product.

The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product.
