MCP3221  
Low Power 12-Bit A/D Converter With I2C™ Interface  
Features  
Description  
• 12-bit resolution  
The Microchip Technology Inc. MCP3221 is a  
successive approximation A/D converter with 12-bit  
resolution. Available in the SOT-23-5 package, this  
device provides one single-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 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  
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.  
• 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-23-5 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 non-linearity and ±2 LSB integral non-lin-  
earity, maximum.
