ADC 19 Click is a compact add-on board that contains a high-performance data converter. This board features the ADC122S101, a low-power two-channel CMOS 12-bit analog-to-digital converter from Texas Instruments. This SPI configurable analog-to-digital converter (ADC) is fully specified over a sample rate range of 500ksps to 1Msps, offering high reliability and performance. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit configurable to accept one or two input signals at its input channels. This Click board™ offers high accuracy solution for the most demanding applications, from general-purpose remote data acquisition applications to portable consumer electronics and more.
ADC 19 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
ADC 19 Click as its foundation uses the ADC122S101, a high-performance two-channel CMOS analog-to-digital converter (ADC) from Texas Instruments. The ADC122S101 comes with an integrated 12-bit SAR-ADC, input multiplexer, and control logic block, allowing ADC to communicate with MCU through a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, this ADC is fully specified over a sample rate range of 500ksps to 1Msps. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit configurable to accept one or two input signals at its input channels.
This ADC 19 Click communicates with MCU through a standard SPI interface and operates at clock rates up to 16MHz, providing data in digital format of 12-bits. The output serial data is straight binary and is compatible with several standards, such as SPI, QSPI, MICROWIRE, and many standard DSP serial interfaces.
This 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 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.
