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