2.5 EVALUATING THE MCP48FEBXX DIGITAL-TO-ANALOG CONVERTERS
The MCP48FEBXX are single and dual-channel, 8-bit, 10-bit, and 12-bit, buffered
voltage output Digital-to-Analog Converters (DAC) with nonvolatile memory and an
SPI serial interface.
The DAC reference voltage can be selected as the VREF pin, the device V
DD
or the
internal band gap voltage. When V
DD
is selected, V
DD
is connected internally to the
DAC reference circuit. When the V
REF
pin is used, the output buffer’s gain to can be
selected to be 1x or 2x. When the gain is 2x, the V
REF
pin voltage should be limited to
a maximum of V
DD/2
.
Figure 2-10 shows the pinouts of the MCP48FEBXX family.
