2. Soldering the headers Before using your click board , make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 DAC 3 click 2 3 4. Essential features DAC 3 click contains two analog output screw terminals: Vout and GND. 16-bit data is sent to the DAC through I2C. The digital value is converted to the appropriate voltage level in the range between GND and REFERENCE (VCC or 4.096V), which is proportional to Turn the board upside down so that Turn the board upward again. Make sure the received 12-bit number. MCP4726 also the bottom side is facing you upwards. to align the headers so that they are integrates EEPROM for storing DAC register Place shorter pins of the header into the perpendicular to the board, then solder the and configuration bit values. appropriate soldering pads. pins carefully. 1. Introduction DAC 3 click carries Microchips MCP4726, a 12-bit digital-to-analog converter, along with 3. Plugging the board in voltage output screw terminals. The IC has click EEPROM, configurable reference voltage, and Once you have soldered the headers your communicates with the target board MCU board is ready to be placed into the desired BOARDS through the mikroBUS I2C interface (SCL, mikroBUS socket. Make sure to align the cut www.mikroe.com SDA pins). Standard (100 kHz), fast (400 in the lower-right part of the board with the kHz) and highspeed (3.4 MHz) I2C modes are markings on the silkscreen at the mikroBUS available. The board uses either a 3.3V or a 5V socket. If all the pins are aligned DAC 3 click Manual v100 power supply. The board is suitable for sensor correctly, push the board all the calibration, motor control, set point or offset way into the socket. 0100000093788 trimming and many other applications.8.
