1 Kernel driver MCP3021 2 ====================== 3 4 Supported chips: 5 * Microchip Technology MCP3021 6 Prefix: 'mcp3021' 7 Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/21805a.pdf 8 * Microchip Technology MCP3221 9 Prefix: 'mcp3221' 10 Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/21732c.pdf 11 12 Authors: 13 Mingkai Hu 14 Sven Schuchmann <schuchmann@schleissheimer.de> 15 16 Description 17 ----------- 18 19 This driver implements support for the Microchip Technology MCP3021 and 20 MCP3221 chip. 21 22 The Microchip Technology Inc. MCP3021 is a successive approximation A/D 23 converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution. 24 25 These devices provide one single-ended input with very low power consumption. 26 Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C 27 compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are 28 available. The default I2C device address is 0x4d (contact the Microchip 29 factory for additional address options).
