HOW DOES IT WORK?
ADC 14 Click is based on the MAX11108A, a low-power serial ADC from Analog Devices. This 12-bit ADC includes a full power-down mode and a fast wake-up for optimal power management, consuming only 6.6mW while sampling up to 3Msps. The low power consumption extends battery life, as it can go as low as 2.5μA/ksps and even lower in power-down mode. The MAX11108A samples from the analog input in the normal mode of operation while the device is powered up at all times, thereby achieving its maximum throughput rates. In addition, the ADC can operate with 14 cycles per conversion.
The ADC 14 Click accepts a full-scale input from 0V to the power supply or the reference voltage. The digital output corresponds to the analog input over the 2-pin screw terminal. ADC 14 Click can use internal or external as a reference voltage, which you can select over the REF SEL jumper (internal reference selected by default). The MCP1501, a high-precision buffered voltage reference from Microchip, provides a 2.048V internal reference voltage. In addition, you can use an external reference voltage, which you can connect over the REF header.
ADC 14 Click uses a 3-Wire (read-only) SPI serial interface to communicate with the host MCU, supporting up to 48MHz serial clock frequency. The SHD shutdown pin of the mikroBUS™ socket is used to shut down the MCP1501 with a Low logic state if the MCP1501 is not in use.
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. Also, this 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.
