MCP4801/4811/4821  
8/10/12-Bit Voltage Output Digital-to-Analog Converter  
with Internal VREF and SPI Interface  
Features  
Description  
• MCP4801: 8-Bit Voltage Output DAC  
• MCP4811: 10-Bit Voltage Output DAC  
• MCP4821: 12-Bit Voltage Output DAC  
• Rail-to-Rail Output  
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.  
• 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 DAC Output  
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  
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  
load (500 k typical.  
The devices include double-buffered registers,  
allowing a synchronous update of the DAC output  
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).
