0025 Description
0026 -----------
0027
0028 This driver implements support for the Microchip Technology MCP3021 and
0029 MCP3221 chip.
0030
0031 The Microchip Technology Inc. MCP3021 is a successive approximation A/D
0032 converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution.
0033
0034 These devices provide one single-ended input with very low power consumption.
0035 Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C
0036 compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are
0037 available. The default I2C device address is 0x4d (contact the Microchip
0038 factory for additional address options).
