    MCP3004 features 200 ksps sample rate at 5V

    Hi

    I need help to understand speed of SPI Ic MCP3004

    Features:
    10-bit resolution
    Four single-ended channels
    SPI interface
    ±1 LSB DNL
    ±1 LSB INL
    200 ksps sample rate at 5V

    I do not understand meaning of 200 ksps sample rate at 5V. does it means mcp3004 can send one bit to slave at speed of 200 ksps ? Each bit take minimum 200 ksbs for transmission ?

    Look at the data sheet
    SPI runs at 3.6 MHz max (at 5V supply) and ten bits are transferred per sample.
    This gives a conservative 200,000, ten-bit samples per second
