We are currently drafting a PSoC 6 BLE Application Note (AN) on hardware design considerations. Placed here is part 3 of the AN, covering PSoC 6 BLE hardware considerations for the analog system. Some analog features in PSoC 6 BLE are CapSense, that enables self and mutual capacitive-sensing for user interfaces, a 12-bit SAR ADC with a sampling rate up to 2Msps, and a 12-bit Continuous Time DAC (CTDAC) that provides a continuous time output without the need for an external sample and hold circuit. This draft explains recommended ports and output paths for PSoC 6 BLE analog features such as CapSense, the SAR ADC, and the Continuous Time DAC.
Feel free to read through and leave your feedback or questions in the comments section. We appreciate the feedback!
