DAC 7 Click carries the AD5624R, a low-power four-channel, 12-bit buffered Digital-to-Analog Converter. AD5624R converts digital value to the corresponding voltage level using external voltage reference. This will help you convert digital information from the main board to four analog outputs on the DAC 7 Click. For that purpose, DAC 7 Click uses MCP1541, which is a low-dropout precision voltage reference with 4.096V output voltage. With all those possibilities on board, DAC 7 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 7 Click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development.

DAC 7 Click is an advanced 12-bit, four-channel digital to analog converter (DAC). This device communicates with the main MCU through the is compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. Also, there is a selectable voltage reference as well with onboard jumpers which makes this Click more open for specific projects.

The main active component on DAC 7 Click board™ is AD5624R from Analog Devices. This is a low power, four channel, 12-bit voltage output Digital-To-Analog Convertor (DAC). It is specified monotonic by design across a wide power supply range from 2.7 V to 5.5 V. Using an external reference, the AD5624R provides a full-scale output voltage in the range from 0V to Vref, while consuming 0.1 mA quiescent current per channel. The AD5624R 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 7 Click has a high precision voltage reference included onboard. For that purpose we have used 4.096V precision voltage reference MCP1541 from Microchip. This little SOT23 device is stable with capacitive loads. It has regulations for both sink and source and is very accurate. This gives DAC 7 click good flexibility for use in various applications.

Low quiescent current, wide power supply range, and per channel power down option makes AD5624R ideal for low power, battery operated system. The device communicates through SPI interface. Besides the standard SPI, QSPI™, MICROWIRE™, and DSP interface standards are also supported. However, this Click board™ is using standard SPI communication with the main MCU.

The reference voltage level can be selected via VREF SEL jumper, between 4.096V and 5V. This allows for both 4.096V and 5V Voltage outputs from DAC 7 Click can be connected through 9-therminal block where first is common GND and the last eight are VOUTA to VOUTH.

This Click board™ is designed to be operated only with 5V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 3.3V.
