PRODUCT SPECIFICATION
nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
7.3
The Analog to digital converter has four analog input channels and one reference
voltage input. Analog input is selected with CHSEL in the ADC_CONFIG_REG.
7.4
To get accurate internal biasing, an external low tolerance resistor is used. A resistor of
22k
proper operation of nRF9E5.
7.5
nRF9E5 has internal regulator used for optimum performance and minimum power
dissipation in digital part of the system. De-coupling of the regulated power is needed
for proper operation of the chip. A capacitor of 10nF should be connected between
DVDD_1V2 and ground as close to the chip as possible. Please see PCB layout and de-
coupling guidelines for further information regarding layout.
