# Title: DAC 8 Click Board™ ## Description: How Does The DAC 8 Click Board™ Work? The DAC 8 Click Board™ is based on the DAC8554IPWR, a 16-bit QUAD channel, ultra-low glitch, voltage-output digital to analog converter from Texas Instruments. It offers good linearity, exceptionally low glitch, and it has high precision output amplifier that allows rail-to-rail output swing over a wide range of supply voltage. What this component additionally has is a Power-On reset function, which ensures that DAC outputs power-up at zero-scale and remains there until a proper write operation occurs. Also, it provides a power-down feature that reduces the current consumption to 175nA per channel. To achieve a fully flexible range of the DAC8554IPWR, an external voltage reference is made user-programmable. For this purpose, the Click board™ uses another DAC, DAC60501MDGSR, 12-bit DAC from Texas Instruments, whose output is brought to the VREF pin of the DAC8554IPWR. That way, the reference voltage of the DAC8554IPWR can be set at any value between 0V and 5V, provides high precision and low power consumption as well. That makes the DAC 8 Click fully customizable solution, well suited for applications where the maximum precision from the output 16-bit DAC is needed. DAC60501MDGSR uses the I2C serial interface to communicate with the MCU and operates at clock rate up to 100kHz. The DAC 8 Click Board™ communicates with MCU using the 3-Wire SPI serial interface that is compatible with standard SPI, QSPI™, MICROWIRE™ and operates at clock rates up to 50 MHz. Additional functionality such as software simultaneous update capability is implemented and routed at the PWM pin of the mikroBUS™, which allows when new data enter the device, all of DAC outputs can be updated simultaneously and synchronously with the clock. It also possesses enable function routed at CS pin of the mikroBUS™ that is used to connect the SPI interface to the serial port. The DAC 8 Click Board™ is designed to be operated with both 3.3V and 5V logic levels. The onboard SMD jumper labeled as VCC SEL allows voltage selection for interfacing with both 3.3V and 5V MCUs.

Additional Notes and Information

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

MIKROSDK

The DAC 8 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
