Slope A/D Resolution, Speed, Voltage Range, and Capacitor Selection
The Slope A/D module allows many trade-offs. For a conversion the user needs to make the fol-
lowing Trade-offs:
• The Resolution of the Result
• The Speed of the Conversion
• The Analog Input Voltage Range
• The External Capacitor
The resolution is the number of bits that is used by the ADTMR to represent the measured input
voltage. This resolution affects the time that the conversion can be completed in.
shows the trade-off between the resolution of the conversion and the maximum conversion time.
The conversion time for the Slope A/D converter can be calculated using the equation:
Therefore at 4 MHz, the conversion time for 16 bits is 16.384 msec. Conversely, it is 256 sec for
10-bits.
Table 24-1: ADTMR Initialization Values and Conversion Times
Resolution
Conversion Time = (1/Fosc) x 2
Where Fosc is the oscillator frequency and N is the number of bits of resolution desired.
