... AIN 3 2003 Microchip Technology Inc. Description 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 µ ...
