PRODUCT SPECIFICATION
nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
When ADCRUN is high the ADC is running continuously. Cycle time t
between each conversion. EOC indicates every time a new conversion value is stored in
ADC_DATA_REG.
where N is number of resolution bits. Figure 9 shows 10-bit conversion where
ADCRUN is set high.
A 500 kHz clock (ADCCLK) clocks the AD converter. Table 20 shows t
function of resolution.
