Industrial RF transceiver

9.6.13 Analog-to-digital converter (ADC)

The ADC is a 10 bit successive approximation analog to digital converter using charge

redistribution techniques to achieve very low power consumption but also a high data

conversion rate.

Features:

• 10 bit A-D conversion

• Selection between four input channels

• Selection between four reference voltages

• Power efficient and area saving switched capacitor charge tank

• Typical A-D conversion time of 37 µs

• Dynamic range up to the maximal supply level VDD_DIG

• Ratiometric measurement possible

• End-of-conversion and Data overflow flagging

• Interrupt generation for End-of-conversion

The ADC is configured and the resulting data can be read out via bit fields. It does not

include multiple data buffering. Thus if previous conversion data was not read when a

subsequent conversion is finished previous data will be overwritten which is flagged with

an overflow flag.
