1. The Track and Hold Acquisition Time is given by:
AT91SAM9G45
The ADC internal clock is divided by 2 in order to generate a clock with a duty cycle of 75%. So the maximum conversion
time is give by:
The full speed is obtained for an input source impedance of < 50 Ohms maximum, or TTH = 500 ns.
In order to make the TSADC work properly, the SHTIM field in TSADCC Mode Register is to be calculated according to this
Track and Hold Acquisition Time, also called Sampled and Hold Time.
