Low Power 12-Bit A/D Converter With I2C™ Interface  
Features  
Description  
• 12-bit resolution  
The Microchip Technology Inc. MCP3221 is a succes-  
sive approximation A/D converter with 12-bit resolu-  
tion. Available in the SOT-23 package, this device  
provides one single-ended input with very low power  
consumption. Based on an advanced CMOS technol-  
ogy, the MCP3221 provides a low maximum conver-  
sion 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.  
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 indepen-  
dent timing for the I2C and conversion clocks. The  
device is also addressable, allowing up to eight devices  
on a single 2-wire bus.  
• ±1 LSB DNL, ±2 LSB INL max.  
• 250 µA max conversion current  
• 5 nA typical standby current, 1 µA max.  
• 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  
• 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:  
- Industrial: -40°C to +85°C  
- Extended: -40°C to +125°C  
• Small SOT-23 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 differ-  
ential non-linearity and ±2 LSB integral non-linearity,  
maximum.  
Applications  
• Data Logging  
• Multi-zone Monitoring  
• Hand-Held Portable Applications  
• Battery-Powered Test Equipment  
• Remote or Isolated Data Acquisition
