Key Features
Overview
Le DAC 10 Click Board™ est une carte complémentaire compacte qui contient un convertisseur numérique-analogique complet et extrêmement précis. Cette carte comprend le DAC53401, un convertisseur numérique-analogique intelligent à sortie de tension 10 bits de Texas Instruments. Cet appareil consomme extrêmement peu d'énergie et dispose d'une mémoire non volatile (NVM), d'une référence interne et d'une interface série I2C avec une adresse esclave configurable. Il fonctionne soit avec une référence interne, soit avec l'alimentation comme référence et fournit une sortie pleine échelle de 1,8 V à 5,5 V.
Le Carte à clic DAC10™ est une carte complémentaire compacte qui contient un convertisseur de données hautes performances qui représente un excellent choix pour des applications telles que la génération de points de polarisation LED et à usage général, le contrôle de l'alimentation, la référence programmable, etc.

How Does The DAC 10 Click Board™ work?
The DAC 10 Click Board™ as its foundation uses the DAC53401, a 10-bit voltage-output smart digital-to-analog converter from Texas Instruments. This device consumes extremely low power and has a non-volatile memory (NVM), an internal reference, and an I2C serial interface. It also has a power-on-reset circuit that makes sure all the registers start with default or user-programmed settings using NVM. It operates with either an internal reference or the power supply as a reference and provides full-scale output from 0V to 5.5V.
The DAC53401 includes digital slew rate control and supports basic signal generation such as square, ramp, and sawtooth waveforms. It also can generate pulse-width modulation (PWM) output with the combination of the triangular or sawtooth waveform and the VFB terminal. The DAC53401 is also called a smart DAC device because of its advanced integrated features. The force-sense output, PWM output, and NVM capabilities of this smart DAC enable system performance and control without using the software. These features allow DAC53401 to go beyond a conventional DAC's limitations that depend on a processor to function.
The DAC 10 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency up to 100kHz, Fast Mode up to 400kHz, and Fast Mode Plus up to 1MHz. Besides, it also allows the choice of the three least significant bits of its I2C slave address by positioning the SMD jumper labeled as ADDR SEL to an appropriate position marked as 0, 1, SCL, and SDA, providing the user with a choice of 4 I2C Slave addresses.
The DAC 10 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
