Application Note
1 Introduction
ATtiny devices have a successive approximation Analog-to-Digital Converter
(ADC) capable of conversion rates up to 15kSPS with a resolution of 10 bits. It
features a flexible multiplexer, which allows the ADC to measure the voltage at
multiple single ended input pins and two internal channel from internal temperature
sensor and bandgap reference in the device. Single ended input channels are
referred to ground.
This application note describes the basic functionality of the ADC in Atmel^®
tinyAVR^® devices in Single ended mode with code examples on Atmel ATtiny88 to
get started. The code examples are written in assembly language and C language.
