Microchip (MCP4822-E/P) Digital to Analogue Converter, Dual, 12 bit

Digital to Analogue Converter, Dual, 12 bit, 3 Wire, Serial, 2.7V to 5.5V, DIP,8 PinsProduct OverviewThe MCP4822-E/P is a dual channel, 12bit voltage output DAC (Digital to AnalogueConverter) with internal voltage reference in 8 pin DIP package. The device hashigh precision internal voltage reference (VREF = 2.048V). The user canconfigure full scale range of device to be 2.048V or 4.096V by setting gainselection option bit (gain of 1 of 2). Each DAC channel can be operated inactive or shutdown mode individually by setting configuration register bits. Inshutdown mode, most of internal circuits in shutdown channel are turned off forpower savings and output amplifier is configured to present a known highresistance output load (500Kohm typical). The MCP4822-E/P provides high accuracyand low noise performance. The devices utilize resistive string architecturewith its inherent advantages of low DNL error, low ratio metric temperaturecoefficient and fast settling time.Rail to rail outputSPI interface with 20MHz clock supportSimultaneous latching of dual DACsFast settling time of 4.5µsSelectable unity or 2x gain output50ppm/°C VREF temperature coefficientSingle supply operation from 2.7V to 5.5VOperating temperature range from -40°C to 125°CApplicationsSignal Processing, Consumer Electronics, Portable Devices, AutomotiveProduct InformationResolution (Bits): 12bitSampling Rate: -Supply Voltage Range: 2.7V to 5.5VADC / DAC Case Style: DIPNo. of Pins: 8PinsInput Channel Type: SerialData Interface: 3 Wire, SerialOperating Temperature Min: -40°COperating Temperature Max: 125°CProduct Range: MCP4802/4812/4822MSL: MSL 1 - Unlimited
