A-D Converter
Table 1.17.1. Performance of A-D converter
Note 1: Does not depend on use of sample and hold function.
Note 2: Divide the frequency if f(X
The A-D converter consists of one 10-bit successive approximation A-D converter circuit with a capacitive coupling
amplifier. Pins P10
these pins for A-D conversion must therefore be set to input. The Vref connect bit (bit 5 at address 03D7
used to isolate the resistance ladder of the A-D converter from the reference voltage input pin (V
converter is not used. Doing so stops any current flowing into the resistance ladder from V
dissipation. When using the A-D converter, start A-D conversion only after setting bit 5 of 03D7
The result of A-D conversion is stored in the A-D registers of the selected pins. When set to 10-bit precision, the low
8 bits are stored in the even addresses and the high 2 bits in the odd addresses. When set to 8-bit precision, the low
8 bits are stored in the even addresses.
Table 1.17.1 shows the performance of the A-D converter. Figure 1.17.1 shows the block diagram of the
A-D converter, and Figures 1.17.2 and 1.17.3 show the A-D converter-related registers.
