Hi! as seen clearly on docs, sampling mode (S&H Cap connected to port) starts after the selection of the input chanel. And ends when the device receive the I2C repeated Start condition.
My hardware follows all the indications about the reservoir capacitor and loading resistor according to the ADS7828 specs (great docs! ) but my readings are always lower than expected, specially when connected with non-buffered sensor outputs.
I suspect that my software does not let enough time to the capacitor reach the sensor voltage level.
1. Can this generate the readings lower than expected?
2. The ADC sampling Mode Time is user-controllated?
Thanks a lot for your support!
