AD8236 REF pins can be grounded? (Driver ADUC7060 ADC Applied to 4-20 mA electric current loop )
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…
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.
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…
You could check the ff ADI instrumentation amplifiers
AD8220
AD8224
AD8236
By the way, what is your intended application?
Hi Robnier,
What do you mean by "it is always grounded"? Referring to the output of the AD8236 or it is the voltage present on the reference pin? Also you should not use a supply voltage of +/- 5V to this chip since the absolute maximum rating of the…
Hi Chris,
In my experience with EM Flow sensors, the output resistance of the sensor can be very large, more than 1MegΩ in some cases, and a high input impedance amplifier can improve the performance in such cases. AD8236 has a very high input impedance…

Figure 42 in the AD8236 datasheet shows an ECG application circuit that I'd like to use. However the cutoff frequency of the low pass filter in the circuit is not what I'd like. How do I change it?
暂时没有 AD8853做为心率检测的资料， 主要的资料 使用了 AD620 AD8232 AD8421 AD8422 AD8236
