MCP4921-E/SN 12 Bit Digital to Analog Converter

The MCP4901/4911/4921 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 user can configure the full-scale range of the device to be VREF or 2*VREF by setting the gain selection option bit (gain of 1 of 2). internal circuits are turned off for power savings, and the output amplifier is configured to present a known high resistance output load (500 ktypical.
