MCP3221  
Low-Power 12-Bit A/D Converter with I2C Interface  
Features  
General Description  
• 12-bit Resolution  
Microchip’s MCP3221 is a successive approximation  
A/D converter (ADC) with a 12-bit resolution. Available  
in the SOT-23 package, this device provides one sin-  
gle-ended input with very low-power consumption.  
Based on an advanced CMOS technology, the  
MCP3221 provides a low maximum conversion current  
and standby current of 250 µA and 1 µA, respectively.  
Low-current consumption, combined with the small  
SOT-23 package, make this device ideal for battery-  
powered and remote data acquisition applications.  
• ±1 LSB DNL, ±2 LSB INL maximum  
• 250 µA Max Conversion Current  
• 5 nA Typical Standby Current, 1 µA maximum  
• I2C Compatible Serial Interface  
- 100 kHz I2C Standard mode  
- 400 kHz I2C Fast mode  
• Up to 8 Devices on a Single 2-wire Bus  
• 22.3 ksps in I2C Fast mode  
Communication to the MCP3221 is performed using a  
2-wire, I2C compatible interface. Standard (100 kHz)  
and Fast (400 kHz) I2C modes are available with the  
device. An on-chip conversion clock enables  
independent timing for the I2C and conversion clocks.  
The device is also addressable, allowing up to eight  
devices on a single 2-wire bus.  
• Single-Ended Analog Input Channel  
• On-Chip Sample and Hold  
• On-Chip Conversion Clock  
• Single-Supply Specified Operation: 2.7V to 5.5V  
Temperature Range:  
- Extended: -40°C to +125°C  
• Small SOT-23-5 package  
The MCP3221 runs on a single-supply voltage that  
operates over a broad range of 2.7V to 5.5V. This  
device also provides excellent linearity of ±1 LSB  
differential nonlinearity (DNL) and ±2 LSB integral  
nonlinearity (INL), maximum.  
Applications  
• Data Logging  
• Multi-Zone Monitoring  
• Handheld Portable Applications  
• Battery-Powered Test Equipment  
• Remote or Isolated Data Acquisition
