General description
The MCP4802/4812/4822 devices are dual 8-bit, 10-bitand 12-bit buffered voltage output Digital-to-AnalogConverters (DACs), respectively. The devices operatefrom a single 2.7V to 5.5V supply with SPI compatibleSerial Peripheral Interface.The devices have a high precision internal voltagereference (VREF = 2.048V). The user can configure thefull-scale range of the device to be 2.048V or 4.096V bysetting the Gain Selection Option bit (gain of 1 of 2).Each DAC channel can be operated in Active orShutdown mode individually by setting the Configurationregister bits. In Shutdown mode, most of the internalcircuits in the shutdown channel are turned off for powersavings and the output amplifier is configured to presenta known high resistance output load (500 k typical.The devices include double-buffered registers,allowing synchronous updates of two DAC outputsusing the LDAC pin. These devices also incorporate aPower-on Reset (POR) circuit to ensure reliable powerup.The devices utilize a resistive string architecture, withits inherent advantages of low DNL error, low ratiometric temperature coefficient and fast settling time.These devices are specified over the extendedtemperature range (+125°C).The devices provide high accuracy and low noiseperformance for consumer and industrial applicationswhere calibration or compensation of signals (such astemperature, pressure and humidity) are required.The MCP4802/4812/4822 devices are available in thePDIP, SOIC and MSOP packages.
