ZoomingADC for Pressure and Temperature Sensing
ZADC Detailed Functionality Description
Continuous-Time vs. On-Request
The ADC can be operated in two distinct modes: "continuous-time" and "on-request" modes (selected using the
bit CONT).
In "continuous-time" mode, the input signal is repeatedly converted into digital. After a conversion is finished, a
new one is automatically initiated. The new value is then written in the result register, and the corresponding
internal trigger pulse is generated. This operation is sketched in Figure 9. The conversion time in this case is
defined as TCONV.
Figure 9 - ADC "Continuous-Time" Operation
In the "on-request" mode, the internal behavior of the converter is the same as in the "continuous-time" mode,
but the conversion is initiated on user request (with the START bit). As shown in Figure 10, the conversion time
is also TCONV.
