ADC 18 Click is a compact add-on board that contains a high-performance data converter. This board features the MAX22005, an SPI-configurable twelve-channel 24-bit analog-to-digital converter (ADC) from Analog Devices. Input channels can be used as twelve single-ended, six differential, and up to eight multichannel configurable differential inputs. In total, the device supports up to 26 different configurations. The ADC is used with an integrated 5ppm\/\u00b0C precision reference. Using high-voltage, zero-drift input amplifiers, standard industrial analog input voltage ranges are converted to the ADC input voltage range. This Click board\u2122 offers high accuracy for the most demanding applications, from general-purpose remote data acquisition to industrial applications.<\/p>\n\n
ADC 18 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.<\/p>\n\n
ADC 18 Click as its foundation uses the MAX22005, a high-performance twelve-channel analog-to-digital converter from Analog Devices. The MAX22005 comes with an integrated 24-bit delta-sigma ADC, input multiplexer, signal conditioning, and control logic block allowing ADC to communicate with MCU through a high-speed serial interface. An integrated delta-sigma ADC is shared between all channels with an integrated 5ppm\/\u00b0C precision reference. Using high-voltage, zero-drift input amplifiers, standard industrial analog input voltage ranges are converted to the ADC input voltage range.<\/p>\n\n
Input channels can be used as twelve single-ended, six differential, and up to eight multichannel configurable differential inputs. In total, the device supports up to 26 different configurations. The MAX22005 can also be configured as an analog-input current-mode device using an external precision resistor per channel or configurable analog-input using an external precision resistor and low-cost switch per channel. All input ports are robustly protected up to \u00b136V reverse polarity and \u00b12kV surge pulses without the need for TVS diodes and factory calibrated with a best-in-class system performance of less than 0.05% FSR Total-Unadjusted-Error (TUE) over temperature.<\/p>\n\n
ADC 18 Click communicates with MCU through a standard SPI interface and operates at clock rates up to 30MHz, for all configurations and information management and acquiring conversion results. In addition, it also uses several mikroBUS\u2122 pins. An active-low reset signal routed on the RST pin of the mikroBUS\u2122 socket activates a hardware reset of the system, while the INT pin on the mikroBUS\u2122 socket represents a standard interrupt feature providing a user with feedback information. It also has an additional data ready interrupt marked as RDY and routed on the AN pin of the mikroBUS\u2122 socket, used to signal when a new ADC conversion result is available in the data register.<\/p>\n\n
This Click board\u2122 can be operated only with a 3.3V logic voltage level. It also has an analog inputs external power supply terminal where it is necessary to bring \u00b115V to accept \u00b1 10V inputs, whose full-scale range is \u00b1 12.5V. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board\u2122 comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.<\/p>\n\n
