Industry-Standard, Complete 12-Bit ADCs
Table 1. Truth Table
After the conversion is completed, data can be obtained
by the microprocessor. The ADCs have the required
logic for 8-, 12-, and 16-bit bus interfacing, which is
determined by the 12/8 input. If 12/8 is high, the ADCs
are configured for a 16-bit bus. Data lines D0–D11 may
be connected to the bus as either the 12 MSBs or the 12
LSBs. The other 4 bits must be masked out in software.
For 8-bit bus operation, 12/8 is set low. The format is left
justified, and the even address, A0 low, contains the 8
MSBs. The odd address, A0 high, contains the 4 LSBs,
which is followed by 4 trailing 0s. There is no need to
use a software mask when the ADCs are connected to
an 8-bit bus.
Note that the output cannot be forced to a right-justified for-
mat by rearranging the data lines on the 8-bit bus interface.
