DAC 5 Click carries Texas Instruments DAC53608 IC, a low-power, eight-channel, 10-bit buffered Digital-to-Analog Converter. DAC53608 converts digital value to the corresponding voltage level using external voltage reference. For that purpose, DAC 5 Click uses MAX6106, which is a low-dropout micropower voltage reference with 2,048V output voltage. With all those possibilities on board, DAC 5 Click makes a perfect choice for an accurate and simple generation of analog signals for various purposes, such as programmable Power Supplies, Laser Drivers, Projectors, IP Network cameras, auto focus digital still camera lens, and more.

DAC 5 Click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development.

DAC 5 Click is an advanced 10-bit eight-channel digital to analog converter (DAC). This device communicates with the main MCU through the I2C interface, supporting the standard mode (100 kbps), fast mode (400 kbps), and fast+ mode (1 Mbps). Also, there is a selectable voltage reference as well with onboard jumpers which makes this Click more open for specific projects. I2C address can be selected with a cross-shaped jumper if such option is needed. DAC 5 Click allows fine tuning to meet any specific project in mind.

DAC53608 from Texas Instruments is the main active component onboard on DAC 5 Click. This is a low power, eight channel, 10-bit voltage output Digital-To-Analog Convertor (DAC). It is specified monotonic by design across a wide power supply range from 1,8 V to 5,5 V. Using an external reference, the DAC53608 provides a full-scale output voltage in the range from 0V to Vref, while consuming 0,1 mA quiescent current per channel. The DAC53608 also includes per channel, user programmable, power down registers facilitate the DAC output buffers to start in a power down to 10K state and remain in this state until a power up command is issued to these output buffers.

The DAC 5 Click has a high precision voltage reference included onboard. For that purpose, MAX6106 is used, a 2.048V voltage reference IC, from Analog Devices. This little SOT23 device is stable with capacitive loads, and no output capacitor is required. It has regulations for both sink and source and is very accurate. This gives DAC 5 Click good flexibility for use in various applications.

Low quiescent current, wide power supply range, and per channel power down option makes DAC53608 ideal for low power, battery operated system. The device communicates through I2C interface. These devices support I2C standard mode (100 Kbps), fast mode (400 Kbps) and fast+ mode (1 Mbps). These devices also have a load DAC (LDAC) pin that allows simultaneous DAC updates. LDAC pin is tied with a mikroBUS™ PWM pin. The I2C lines (SCL and SDA) are routed to the dedicated mikroBUS™pins.

The voltage level of the logic section can be selected via VCC SEL jumper, between 3.3V and 5V. This allows for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. For I2C address selection, DAC 5 Click has cross-shape jumper. There are four positions for I2C selection which can be selected with a SMD 0 ohms resistor. DAC 5 Click has Vref SEL jumper for choosing between 2,048 V and 1,024 V, where 1,024 V is achieved using a voltage divider. Another jumper is for VrefIN and choosing between Vref (1,024 and 2,048) and VCC (3,3V and 5V). Voltage outputs from DAC 5 Click can be connected through 9-therminal block where first is common GND and the last eight are VOUTA to VOUTH.
