• Analog sig processing using AD8236 and AD8609

    Hi, 

    I am hoping someone can help?

    I have designed a simple ECG analog processing path feeding in to one of the available A/D modules of a PIC microcontroller (24FJ128GA310).

    My issue is that one of my analog rails for the analog path and the PIC A/D module…

  • issue with my design using AD8236 op-amp

    Hello everyone,

    I am designing a circuit to measure the current passing through a load using a shunt resistor and an instrumental amplifier AD8236, but i am obtaining a wrong output value in my circuit but i don't know where is my mistake. I attached my…

  • Why the inputs of AD8236 need to be pulled to VDD and VCC in application of ECG measurement

    Hi everyone,

    Now I made a circuit to measure ECG based on the AD8236. I followed the example in the AD8236 manual as shown below.

    But when I test with electrodes connected to the human body, I found the output of AD8236 remained 2.5v. I cannot see the…

  • AD8236 REF not passing to output

    Hi I've simple differential configuration amplifier with ref powered from 1/2VCC VCC is 3.3V. Differential signal is output from AMC1200. When I tried to power it up I have nothing on output.

  • AD8236 Level-Shift Output (pin 7) offset

    Our AD8236 level-shift output at p7 has an offset relative to a stable and accurate Vref at pin 6. What conditions or issues could cause the AD8236 to (pin 7) output level shift to not match the provide REF at pin6? Could capacitive loading on the AD8236…

  • AD8236/AD8235

    Hi,

    I've been using the AD8236 to make an EMG amplifier. I connected a second order low pass MFB butterworth filter at @20Hz cutoff , which filters the AD8236 output and feeds it to the reference pin. I am not pleased with the results. while the DC correction…

  • Instrumentation Amplifier

    previously  I'm  using  more than 40 numbers  AD8236 in a  instrument , the reason for choosing this  Low power consumption ,so the battery charge can stand up to our requirement time ,  but now AD8236 is out of stock , I'm searched for other IN-amp which…

  • OP90 used as inamp

    Q 

    Please explain how to use OP90 as instrumentation amplifier as shown in figure
    11 of it's datasheet Rev C.

    This is a funky application where they use the Vos pins to unbalance the front
    end and then provide feedback on the other Vos pin.
