AD Converter
The nRF9E5 AD converter has up to 10-bit dynamic range and linearity with a
conversion rate of 80 ksps used at the Nyquist rate. The reference for the AD converter
is software selectable between the AREF input and an internal 1.22V bandgap reference.
The converter has 5 inputs selectable by software. Selecting one of the inputs 0 to 3 will
convert the voltage on the respective AIN0 to AIN3 pin. Input 4 enables software to
monitor the nRF9E5 supply voltage by converting an internal input that is VDD/3 with
the 1.22V internal reference selected. The AD converter is typically used in a start/stop
mode. The sampling time is then under software control. The converter is by default
configured as 10 bits. For special requirements, the AD converter can be configured by
software to perform 6, 8 or 12 bit conversions. The converter may also be used in
differential mode with AIN0 used as negative input and one of the other 3 external
inputs used as noninverting input.
1.9
Radio Transceiver
The transceiver part of the circuit has identical functionality to the nRF905 single chip
RF transceiver. It is accessed through an internal parallel port and / or an internal SPI.
The data ready, carrier-detect and address match signals can be programmed as
interrupts to the microcontroller or polled via a GPIO port.
The nRF905 is a radio transceiver for the 433/868/915 MHz ISM bands. The transceiver
consists of a fully integrated frequency synthesizer, a power amplifier, a modulator and
a receiver unit. Output power and frequency channels and other RF parameters are easily
programmable by use of the on chip SPI interface to the nRF905 core. RF current
consumption is only 11 mA in TX mode (output power -10dBm) and 12.5 mA in RX
mode. For power saving the transceiver can be turned on / off under software control.
This document should be read in conjunction with the nRF905 datasheet.
