App note: Using the A/D Amplifier on AT90PWM

Here’s an application note from Atmel for using the 10-bit ADC amplified conversion on AT90PWM (PDF!): ADC features on Atmel® AVR® AT90PWM devices: – 10-bit ADC amplified conversion with differential inputs – Programmable gain – Internal voltage reference The AT90PWM devices feature a 10-bit successive approximation ADC. The ADC is connected to an analog multiplexer […]
