MCP4728 is a quad channel, 12-bit voltage output Digital-to-Analog Converter with non-volatile memory and I2C compatible Serial Interface.
The user can program the DAC input codes, device configuration bits, and I2C address bits to the non-volatile memory (EEPROM) by using I2C™Compatible interface commands. The non-volatile memory feature enables the DAC device to hold the DAC input codes during power-off time, allowing the DAC outputs to be available immediately after power-up.

 This blank Printed Circuit Board allows 8- and 10-pin devices in the following package types to be installed: MSOP-10, MSOP-8 and DIP-10.This board is generic so that any of the listed devices may be installed. Refer to the device data sheet, however, for suitability of device evaluation.As well as the device, other desired passive components (resistors and capacitors) and connection posts may be installed. This allows the board to evaluate a minimum configuration for the device. |
| The MCP4728 Evaluation Board is a tool for quick and easy evaluation of the MCP4728 4-channel 12-bit DAC device. |

| DAC 4 Click carries Microchip’s MCP4728 IC, a Quad Digital-to-Analog Converter with nonvolatile (EEPROM) Memory. The digital value is converted to the appropriate voltage level in the range between GND and VCC, which is proportional to the received 12-bit number. MCP4726 also integrates EEPROM for storing DAC register and configuration bit values. These options give a lot of flexibility which make it a perfect choice for an accurate and simple generation of analog signals for various purposes, such as PLC/DCS modules, temperature and pressure control, medical and scientific instrumentation, chromatography and other similar applications, where accurate digital to analog conversion is needed.
DAC 4 click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket. |
