 | 12 | ----------- | 
 | 13 |  | 
 | 14 | This driver implements support for the Microchip Technology MCP3021 chip. | 
 | 15 |  | 
 | 16 | The Microchip Technology Inc. MCP3021 is a successive approximation A/D | 
 | 17 | converter (ADC) with 10-bit resolution. | 
 | 18 | This device provides one single-ended input with very low power consumption. | 
 | 19 | Communication to the MCP3021 is performed using a 2-wire I2C compatible | 
 | 20 | interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are available. | 
 | 21 | The default I2C device address is 0x4d (contact the Microchip factory for | 
 | 22 | additional address options). |
