| | 16 | Description |
| | 17 | ----------- |
| | 18 | |
| | 19 | This driver implements support for the Microchip Technology MCP3021 and |
| | 20 | MCP3221 chip. |
| | 21 | |
| | 22 | The Microchip Technology Inc. MCP3021 is a successive approximation A/D |
| | 23 | converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution. |
| | 24 | |
| | 25 | These devices provide one single-ended input with very low power consumption. |
| | 26 | Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C |
| | 27 | compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are |
| | 28 | available. The default I2C device address is 0x4d (contact the Microchip |
| | 29 | factory for additional address options). |
