2. Soldering the headers Before using your click board, make sure to solder the provided 1x8 male headers to both sides of the board. Two 1x8 male headers are included with the board in the package. 1 DAC click 2 3 1. Introduction 4. Creating Output Voltages Board contains two analog output screw terminals: Vout and GND. Data in 12-bit format is sent to the DAC using SPI Turn the board upside down, so that Turn the board upward again. Make sure communication interface. This data is bottom side is facing you upwards. Place to align the headers so that they are converted to the appropriate voltage level shorter parts of the header pins in the perpendicular to the board, then solder the in the range between GND and REFERENCE Front and back side appearance both soldering pad locations. pins carefully. (VCC or 4.096V), which is proportional to the of the DAC click Board received 12-bit number. DAC Click is an accessory board in mikroBus form factor. It includes a 12-bit Digital-to- 3. Plugging the board in Analog Converter MCP4921 that features click SPI interface and an optional double buffered Once you have soldered the headers your output. The board provides high accuracy board is ready to be placed into desired BOARD and low noise performance for industrial mikroBUS socket. Make sure to align the www.mikroe.com applications where calibration or compensation cut in the lower-right part of the board of signals, such as temperature, pressure and with the markings on the silkscreen at the DAC click Manual humidity, are required.
