^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) This driver implements support for the Microchip Technology MCP3021 and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) MCP3221 chip.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) The Microchip Technology Inc. MCP3021 is a successive approximation A/D
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) These devices provide one single-ended input with very low power consumption.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) Communication to the MCP3021/MCP3221  is performed using a 2-wire I2C
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) available. The default I2C device address is 0x4d (contact the Microchip
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) factory for additional address options).
