    Excellent idea!
    Here’s another one that I’ve been using:
    PCF8563 (RTC) – 0x51

    I needed this the other night. Just two I2C devices but of course they both happened to be using 0x68. Luckily the MCP3424 can be configured to use a different address.

    18 bit ADC
    MCP3422 0x68
    MCP3423 0x68-0x6F
    MCP3424 0x68-0x6F

    16 bit ADC
    MCP3426 0x68
    MCP3427 0x68-0x6F
    MCP3428 0x68-0x6F
