Other Parts Discussed in Thread: TIDA-00307, TIDA-00493, TCA6408A
hello,
i am trying to use the ADS8688 to read analog current values from a current sensors of the following values (4 mA to 20 mA, and ±20 mA.)
in the datasheet it is mentioned that this device support current inputs without the need of an external circuit (section 9.2.2.1, page 55)
but after checking the boards (TIDA-00307 and TIDA-00493), i found that it has been used an external circuit (shunt resistor + OA)
so my question is. does the ADC actually support current inputs or not ?
Thanks in advance.
