ADC 17 Click Board™

How Does The ADC 17 Click Board™ Work?

The ADC 17 Click Board™ 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.

The ADC 17 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 of 100kHz and Fast Mode up to 400kHz.

The ADC 17 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.
