Description
The MCP4801/4811/4821 devices are single channel 8-bit, 10-bit and 12-bit buffered
voltage output Digital-to-Analog Converters (DACs), respectively. The devices operate from a single 2.7V to 5.5V supply with an SPI compatible Serial Peripheral Interface.
The devices have a high precision internal
voltage reference (VREF = 2.048V). The us...
