• AD7194: Voltage bias to thermocouple


    I working on Thermocouple amplifier based on AD7194.

    - 3 chanels, S-type, PT100 CJ compensation.

    - ADR421 reference, 2.5V

    - 5V power supply

    Could I use TC voltage biasing according picture below?


  • AD7194 Odd Behavior

    I'm confused by the behavior of my AD7194.

    I have the following configuration:
    - Channel to be measured at AIN1
    - 2.5V reference voltage at AIN9
    - 4.1V reference voltage at REFIN1(+)
    - GND at REFIN1(-)

    I have this configuration due to a separate upstream…

  • interfacing multiple ad7194

    helloo all,

    iam interfacing two AD7194 adc's to a single microcontroller using spi interface. And i use the same chip select pin from the microcontroller to select the two adc's using a MUX. And the steps for reading the data from the adc inc…

  • Recommended update over AD7194

    I'm selecting an ADC for an application measuring seven resistive load cells, using an amplifier gain of 128, in sequence (aiming for an individual rate of about 420 Hz, for a combined sample rate of 60 Hz). I've been using an AD7194 for prototyping,…

  • AD7194 0-10V (pseudo)-differential input

    I'm trying to build an add-on board to a data acquisition board, which has the following input filter:

    I want to attach a secondary board that can have an input between 0 - 10V. The AD7194 has a 5V reference connected to it and therefore the 0-10V…
