MCP4802/4812/4822  
8/10/12-Bit Dual Voltage Output Digital-to-Analog Converter  
with Internal VREF and SPI Interface  
Features  
Description  
• MCP4802: Dual 8-Bit Voltage Output DAC  
• MCP4812: Dual 10-Bit Voltage Output DAC  
• MCP4822: Dual 12-Bit Voltage Output DAC  
• Rail-to-Rail Output  
The MCP4802/4812/4822 devices are dual 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 SPI compatible  
Serial Peripheral Interface.  
• SPI Interface with 20 MHz Clock Support  
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).  
• Simultaneous Latching of the Dual DACs  
with LDAC pin  
• Fast Settling Time of 4.5 µs  
• Selectable Unity or 2x Gain Output  
• 2.048V Internal Voltage Reference  
• 50 ppm/°C VREF Temperature Coefficient  
• 2.7V to 5.5V Single-Supply Operation  
• Extended Temperature Range: -40°C to +125°C  
Each DAC channel can be operated in Active or  
Shutdown mode individually by setting the Configuration  
register bits. In Shutdown mode, most of the internal  
circuits in the shutdown channel are turned off for power  
savings and the output amplifier is configured to present  
a known high resistance output load (500 k typical.  
The devices include double-buffered registers,  
allowing synchronous updates of two DAC outputs  
using the LDAC pin. These devices also incorporate a  
Power-on Reset (POR) circuit to ensure reliable power-  
up.  
Applications  
• Set Point or Offset Trimming  
• Sensor Calibration  
• Precision Selectable Voltage Reference  
• Portable Instrumentation (Battery-Powered)  
• Calibration of Optical Communication Devices  
The devices utilize a resistive string architecture, with  
its inherent advantages of low DNL error, low ratio  
metric temperature coefficient and fast settling time.  
These devices are specified over the extended  
temperature range (+125°C).

Related Products  
The devices provide high accuracy and low noise  
performance for consumer and industrial applications  
where calibration or compensation of signals (such as  
temperature, pressure and humidity) are required.
