TS-7200 Cirrus A/D converter calibration
So, according to the TS-7200 manual, the built-in EP93xx A/D converters
have been calibrated at the factory and calibration values have been
written to the EEPROM. Okay, fine. But the question I have is ...
where is this EEPROM?
I downloaded the sample code provided by TS, and that code mentions the
TS-7250. From looking at that code and pouring over the EP9301 manual,
I am guessing that on the TS-7250 the EEPROM is a serial EEPROM and it's
available on the SPI bus. A look at the TS-7250 schematic confirms this.
But ... I cannot find a comparable EEPROM on the TS-7200 schematic. This
leads me to three possible conclusions:
- There are no calibration values and the documentation is wrong.
- There are calibration values and they're in the same place as on the
TS-7250, I just missed them.
- There are calibration values, but they are hidden somewhere else.
Anyone have any idea what the correct answer is?
