5.16 Analog-to-Digital Converter (ADC)
5.16.1 Overview
5.16.2 Features
NuMicro™ NUC100 Series contains one 12-bit successive approximation analog-to-digital
converters (SAR A/D converter) with 8 input channels. The A/D converter supports three
operation modes: single, single-cycle scan and continuous scan mode. There are two kinds of
scan mode: continuous mode and single cycle mode. The A/D converters can be started by
software and external STADC pin.
Analog input voltage range: 0~Vref (Max to 5.0V)
12-bit resolution and 10-bit accuracy is guaranteed
Up to 8 single-end analog input channels or 4 differential analog input channels
Maximum ADC clock frequency is 16MHz
Up to 600K SPS conversion rate
Three operating modes
An A/D conversion can be started by
Conversion results are held in data registers for each channel with valid and overrun
indicators
Conversion result can be compared with specify value and user can select whether to
generate an interrupt when conversion result is equal to the compare register setting
Channel 7 supports 3 input sources: external analog voltage, internal fixed bandgap
voltage, and internal temperature sensor output
Support Self-calibration to minimize conversion error
Single mode: A/D conversion is performed one time on a specified channel
Single-cycle scan mode: A/D conversion is performed one cycle on all specified
channels with the sequence from the lowest numbered channel to the highest
numbered channel
Continuous scan mode: A/D converter continuously performs Single-cycle scan mode
until software stops A/D conversion
Software write 1 to ADST bit
External pin STADC
