Introduction

While microcontrollers (MCU PIC^®) are primarily digital devices, some microcontrollers contain dedicated Core Independent Peripherals (CIPs) to implement or enhance analog circuitry. The PIC16F17576 is a low-cost microcontroller designed for analog applications with multiple integrated operational amplifiers, a 12-bit Differential Analog-to-Digital Converter with Computation (ADCC), a new low-power voltage reference (V_REFLP) and a low-power analog comparator (CMPLP). To demonstrate the analog features of this MCU family, two demo boards were created. This technical brief discusses the Adaptive Gain demo, while the “Ultra Low-Power Analog Monitoring With the PIC16F17576” application note (AN6177) discusses the low-power demo.
