Description
The MCP47FXBX4/8 devices are a family of buffered voltage output Digital-to-Analog Converters (DAC), with the following options:
quad or octal output channel configurations
8/10/12-bit resolution
Volatile or nonvolatile user memory
The quad and octal options differ only by the number of output channels.The volatile and nonvolatile versions have an identical analog circuit structure.There are three voltage reference sources: the external VREF pin, the device’s VDD
