MCP4901/4911/4921  
8/10/12-Bit Voltage Output Digital-to-Analog Converter  
with SPI Interface  
Features  
Description  
• MCP4901: 8-Bit Voltage Output DAC  
• MCP4911: 10-Bit Voltage Output DAC  
• MCP4921: 12-Bit Voltage Output DAC  
• Rail-to-Rail Output  
The MCP4901/4911/4921 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 user  
can configure the full-scale range of the device to be  
VREF or 2*VREF by setting the gain selection option bit  
(gain of 1 of 2).  
• SPI Interface with 20 MHz Clock Support  
• Simultaneous Latching of the DAC Output  
with LDAC Pin  
• Fast Settling Time of 4.5 µs  
The user can shut down the device by setting the Con-  
figuration Register bit. In Shutdown mode, most of the  
internal circuits are turned off for power savings, and  
the output amplifier is configured to present a known  
high resistance output load (500 ktypical.  
• Selectable Unity or 2x Gain Output  
• External Voltage Reference Input  
• External Multiplier Mode  
• 2.7V to 5.5V Single-Supply Operation  
• Extended Temperature Range: -40°C to +125°C  
The devices include double-buffered registers,  
allowing synchronous updates 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  
• Precision Selectable Voltage Reference  
• Motor Control Feedback Loop  
The devices utilize a resistive string architecture, with  
its inherent advantages of low Differential Non-Linear-  
ity (DNL) error and fast settling time. These devices are  
specified over the extended temperature range  
(+125°C).  
• Digitally-Controlled Multiplier/Divider  
• Calibration of Optical Communication Devices  
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.
