2. Soldering the headers
™
Before using your click board
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. Introduction
DAC 2 click carries LTC2601CDD, a 16-bit
digital-to-analog converter, along with volt-
age output screw terminals. The chip has high
rail-to-rail output drives (±15mA, Min) and
double-buered data latches. The click board
communicates with the target MCU through
the mikroBUS™ SPI interface (MISO, MOSI
pins) with clock rates up to 50MHz. Addition-
ally, the CLR pin, in place of default mikroBUS™
RST pin, clears all the registers. The board
uses either a 3.3V or 5V power supply.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS™ socket. Make sure to align the cut
in the lower-right part of the board with the
markings on the silkscreen at the mikroBUS™
socket. If all the pins are aligned
correctly, push the board all the
way into the socket.
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
converted to the appropriate voltage level
in the range between GND and REFERENCE
(VCC or 4.096V), which is proportional to the
received 16-bit number.
