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 2 click 2 3 4. Essential features DAC 2 click contains two analog output screw terminals: Vout and GND. 16-bit data is sent to the DAC through SPI. The digital value is Turn the board upside down so that Turn the board upward again. Make sure converted to the appropriate voltage level the bottom side is facing you upwards. to align the headers so that they are in the range between GND and REFERENCE Place shorter pins of the header into the perpendicular to the board, then solder the (VCC or 4.096V), which is proportional to the appropriate soldering pads. pins carefully. received 16-bit number. 1. Introduction DAC 2 click carries LTC2601CDD, a 16-bit digital-to-analog converter, along with volt- 3. Plugging the board in age output screw terminals. The chip has high click rail-to-rail output drives (15mA, Min) and Once you have soldered the headers your double-buffered data latches. The click board board is ready to be placed into the desired BOARD communicates with the target MCU through mikroBUS socket. Make sure to align the cut www.mikroe.com the mikroBUS SPI interface (MISO, MOSI in the lower-right part of the board with the pins) with clock rates up to 50MHz. Addition- markings on the silkscreen at the mikroBUS ally, the CLR pin, in place of default mikroBUS socket. If all the pins are aligned DAC 2 click manual ver 1.00 RST pin, clears all the registers.
