11 | Description | |
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). |
