![]() The opamp I used in multisim is OP497 (this was the first one I found in the multisim catalog that had a DIP package)Įdit: I flipped the op amp and now the output seems linear but the peak to peak output voltage is only 45mV. Is there an easier way to do this with only a few parts? This module can be connected to a microcontroller on one side and. Analyzing these signals prepares useful information about heart function, such as heartbeat rate, heart rhythm, and other information regarding the heart’s condition. You can use Arduino in Multisim by installing the Multisim Arduino Library, which allows you to simulate and analyze Arduino circuits using Multisim. ![]() I am trying to amplify a 10µV to 100 µV differential signal to at least 1V using an analog amplifier so that I can measure it using an ADC such as the one on an arduino. The AD8232 sensor can provide you to monitor electrocardiographic or ECG signals. Is the output of this op-amp circuit linear in input voltage? The last equation \$A = \frac\$ seems to imply the output is linear but when I simulated it in multisim with a sine wave input, the output was either a sine with an amplitude of 0.1V or a square wave with amplitude of 4V for small changes in input amplitude. NI Multisim Live lets you create, share, collaborate, and discover circuits and electronics online with SPICE simulation included. ![]() ![]() Now if only I could accept multiple answers. ![]()
