  • INA146: High-Voltage (0-24vdc) Signal Conditioning for Low-Voltage ADCs (3.3vdc)

    Part Number: INA146
    Other Parts Discussed in Thread: LM7705

    Hi everyone,

    I'm trying to seek a simple method to condition high voltage signal (0-24vdc) for low voltage ADC (0-3.3v).

    Specifially, I'll like to scale input  signal of 0-10vdc linearly…

  • ADS1220: High impedance output pH sensor

    Part Number: ADS1220

    Hi,

    I am working with a pH sensor which I would like to connect directly to the ADS1220. The output voltage varies between -414mV and +414mV to represent the 0-14 pH scale. Usually, a buffer amp is required in order to provide necessary…

  • “I Need High Input Impedance!”

    Other Parts Discussed in Post: OPA211, OPA320

    In helping to select op amps and instrumentation amps I frequently hear the comment, “I need really high input impedance.” Oh really?… are you sure?

    It’s rare that input impedance, or more…
