AD CONVERTER SUBSYSTEM
10.1
AD Converter
The nRFE5 AD converter has 10 bit dynamic range and linearity when used at the
Nyquist rate. With lower signal frequencies and post filtering, up to 12 bits resolution is
possible. The reference for the AD converter is selectable between the AREF input and
an internal 1.22V bandgap reference.
The converter default SPI setting is 10 bits. For special requirements, the AD converter
can be configured to perform 6, 8, 10 or 12 bit conversions. The converter may also be
used in differential mode with AIN0 used as inverting input and one of the other 3
external inputs used as noninverting input.
Two

Registers are described in detail in chapter 11.

Selection of input channel is directly embedded in the START_ADC_CONV command,
alternatively it is set by CHSEL in the ADC_CONFIG_REG. Values of CHSEL from 0
to 3 would select AIN0 to AIN3 respectively. Setting CHSEL to [1xxx] will monitor the
nRF9E5 supply voltage by converting an internal input that is VDD/3 with the 1.22V
internal reference.
The AD conversion result is available as ADCDATA in ADC_DATA_REG at the end
of conversion. The data in ADC_DATA_REG is stored according to Table 19 with left
or right justified data selected by ADC_RL_JUST.

Overflow status is stored as ADC_RFLAG in the STATUS_REGISTER after each
conversion.
The complete subsystem is switched off by clearing bit ADC_PWR_UP.
Instructions for the AD converter are given in Table 21 on page 35.
