MCP4801/4811/4821
8/10/12-Bit Voltage Output Digital-to-Analog Converter
with Internal VREF and SPI Interface
Features 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 user can configure the
full-scale range of the device to be 2.048V or 4.096V by
setting the Gain Selection Option bit (gain of 1 of 2).
The devices can be operated in Active or Shutdown
mode by setting a Configuration register bit or using the
SHDN pin. In Shutdown mode, most of the internal
circuits, including the output amplifier, are turned off for
power savings, while the amplifier output (VOUT) stage is
configured to present a known high resistance output …
