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