MIKROE ADC 17 Click

ADC 17 Click is a compact add-on board that contains a high-performance data converter. This board features the MAX11645 a low-power two-channel 12-bit analog-to-digital converter from Analog Devices. The MAX11645 measures two single-ended or one differential input. The fully differential analog inputs are software configurable (I2C interface) for unipolar or bipolar and single-ended or differential operation. The 2.048V internal reference determines its full-scale analog input range. This Click board™ offers complete high accuracy solutions for the most demanding applications from energy-harvesting sensors to portable consumer electronics point-of-load monitoring (voltage current and temperature) and more. ADC 17 Click is supported by a mikroSDK compliant library which includes functions that simplify software development. ADC 17 Click as its foundation uses the MAX11645 a high-performance two-channel analog-to-digital converter (ADC) from Analog Devices. The MAX11645 uses successive-approximation conversion technique and fully differential input track/hold (T/H) circuitry to capture and convert an analog signal to a serial 12-bit digital output. It can measure either two single-ended or one differential input(s). The MAX11645 is capable of sample rates up to 94ksps. By taking advantage of the ADC’s high sample rate multiple channels can be converted in a short period. This capability allows the device to spend more time in shutdown mode reducing total power consumption. It also includes a 2.048V internal reference which determines its full-scale analog input range. The fully differential analog inputs are software configurable for unipolar or bipolar applications; input signals from 0 to VREF (unipolar) or ±VREF/2 (bipolar) range can be resolved with accurate 12-bit accuracy. ADC 17 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
