HOW DOES IT WORK?
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 slave 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.
