Hi andy, Please find this information extract from the AT91SAM9G20 Preliminary datasheet. It is available from here: http://www.atmel.com/dyn/resources/prod_documents/doc6384.pdf - 3.0V to 3.6V VDDANA (Analog-to-digital Converter) -> this is the reference for ADC range input. 4-channel ADC • 10-bit 312K samples/sec. Successive Approximation Register ADC • -2/+2 LSB Integral Non Linearity, -1/+1 LSB Differential Non Linearity • Individual enable and disable of each channel • External voltage reference for better accuracy on low voltage inputs • Multiple trigger source – Hardware or software trigger – External trigger pin – Timer Counter 0 to 2 outputs TIOA0 to TIOA2 trigger • Sleep Mode and conversion sequencer – Automatic wakeup on trigger and back to sleep mode after conversions of all enabled channels • Four analog inputs shared with digital signals
