MCP4821/MCP4822  
12-Bit DACs with Internal VREF and SPI™ Interface  
Features  
Description  
• 12-Bit Resolution  
The Microchip Technology Inc. MCP482X devices are  
2.7V–5.5V, low-power, low DNL, 12-bit Digital-to-Analog  
Converters (DACs) with internal band gap voltage  
reference, optional 2x-buffered output and Serial  
Peripheral Interface (SPI™).  
• ±0.2 LSb DNL (typ.)  
• ±2 LSb INL (typ.)  
• Single or Dual Channel  
• Rail-to-Rail Output  
The MCP482X family of DACs provide high accuracy  
and low noise performance for industrial applications  
where calibration or compensation of signals (such as  
temperature, pressure and humidity) are required.  
• SPI™ Interface with 20 MHz Clock Support  
• Simultaneous Latching of the Dual DACs  
with LDAC pin  
• Fast Settling Time of 4.5 µs  
The MCP482X devices are available in the extended  
temperature range and PDIP, SOIC and MSOP  
packages.  
• Selectable Unity or 2x Gain Output  
• 2.048V Internal Band Gap 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 MCP482X 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. The MCP482X family  
includes double-buffered registers, allowing simulta-  
neous updates 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
