This MPLAB X bare metal example in Using the Internal OPAMP as Regulated Power Supply for MVIO (AN3636) shows how to use the OPAMP as a regulated power supply for a second voltage domain. This removes the need for a second external power supply. The regulated power supply features is showcased by acting as the second power supply for the Multi-V…

This repository provides a Mindi Schematic simulating a core independent overcurrent protection and current draw trigger level using the internal OPAMP, TCD and AC as well as a model of a DC motor.

This Atmel Studio 7 bare metal example in Constant-Current Driver Using the Analog Signal Conditioning (OPAMP) Peripheral (AN3632), shows how to use the OPAMP to implement a constant-current driver using just one external resistor. The OPAMP peripheral also provides the ability to adjust the current setting under firmware control.

These MPLAB X bare metal examples in Getting Started with Multi Voltage I/O (MVIO) (TB3287) show how the MVIO is used on the AVR® DB family of microcontrollers. The MVIO peripheral allows a subset of the I/O pins to be powered by a different I/O voltage domain VDDIO2, eliminating the need for external level shifters

This Atmel START example in Low-BOM Microphone Interface Using the Analog Signal Conditioning (OPAMP) (AN3631) shows how to interface an electret microphone with a microcontroller (MCU) using the OPAMP. In addition to the microphone, only one resistor and one capacitor are required.

This Atmel Studio 7 bare metal code demonstrates the different ways of configuring the Analog Signal Conditioning (OPAMP) peripheral with the AVR128DB48 Curiosity Nano development kit. This is the factory programmed FW on the kit, allowing opamp evaluation without programming.
