SparkFun MIKROE ADC 16 Click

ADC 16 Click is a compact add-on board that contains a high-performance data converter. This board features the ADS7142-Q1, a low-power two-channel 12-bit analog-to-digital converter from Texas Instruments. This I2C configurable 140kSPS successive approximation register (SAR) analog-to-digital converter (ADC) can autonomously monitor signals while maximizing system power, reliability, and performance. It implements event-triggered interrupts per channel using a digital window comparator with programmable high and low thresholds, hysteresis, and event counter. This Click board� offers high accuracy solution for the most demanding applications, from general-purpose monitoring applications (voltage, current, and temperature) to portable consumer electronics and more.

ADC 16 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

ADC 16 Click as its foundation uses the ADS7142-Q1, a high-performance two-channel analog-to-digital converter (ADC) from Texas Instruments. The ADS7142-Q1 represents a dual-channel, 12-bit programmable sensor monitor with an integrated 140kSPS SAR-ADC, input multiplexer, digital comparator, data buffer, accumulator, and internal oscillator. The input multiplexer can be configured as two single-ended channels, one single-ended channel with remote ground sensing, or one pseudo-differential channel where the input can swing to approximately half the value of its analog supply input.

ADC 16 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings. Besides, the ADS7142-Q1 allows choosing the least significant bit (LSB) of its I2C peripheral address using the SMD resistors labeled R8 and R9. This Click board� also implements event-triggered interrupts per channel, labeled as RDY and ALR and routed on the AN and INT pins of the mikroBUS� socket, using a digital window comparator with programmable high and low thresholds, hysteresis, and event counter.

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.
