ADC Conversion Time Calculation in 12 bit operation dsPIC33EP512GM710
I am new to Microchip devices and I am using a dsPIC33EP512GM710 on a Explorer 16/32 development board to sample using an ADC at 12 bit resolution.
I would like to sample at 400 kHz, just shy of the maximum 500 kHz speed advertised by the board. I am using the internal clock for timing the ADC, and the internal counter ends sampling and starts conversion (SSRC = 7).
The manual for the ADC for this microcontroller family states that "The ADC conversion time will be 12 TAD since the ADC module is configured for 10-bit operation, as calculated in Equation 16-9"
Is this true for 12 bit operation as well? Or is it 14 TAD?
