    Arun started the topic Analog input handling in Dataloggers in the forum Other Data Loggers 8 years, 7 months ago

    While designing multi-channel dataloggers (8 to 16 differential analog inputs or even 3-wire RTD input), what is the best approach for ADC – Analog to Digital Conversion?

    In general, we see
    1) Multiplexed input (lesser cost, lesser sampling rate)
    2) Dedicated ADC circuit for each input

    Considering just 1Hz sampling rate (record 1 digital…[Read more]
