11.2 ADC Converter
11.2.1 Description
The GE863-GPS module provides one Analog to Digital Converter. The input line (named
ADC_IN1) is available on BGA Ball #23 of the GE863-GPS module and on pin 19 of PL104 on
EVK2 Board (CS1151).
The GE863-QUAD / PY / SIM modules provide 3 Analog to Digital Converters.
The input lines are available on:
ADC_IN1 on BGA Ball #23 of the module and on pin 19 of PL104 on EVK Interface board.
ADC_IN2 on BGA Ball #74 of the module and on pin 20 of PL104 on EVK Interface board.
ADC_IN3 on BGA Ball #70 of the module and on pin 21 of PL104 on EVK Interface board.
The on board A/D is 11-bit converter. It is able to read a voltage level in the
range of 0÷2 volts applied on the ADC pin input, store and convert it into 11 bit word.
