A company tried to develop an ECG device. They have no experience in ECG signal detection and digital signal acquisition/processing. They tried to use an 8-bit ADC (with 100 Hz sampling rate and 0 to 5 V output) to detect the ECG signal and found that all they got is noise. They hire you to help them find out the issue. You found an ADC of 12 bit, 1 V output, and 1000 Hz sampling rate. For AD624 amplifier, explain to the company what gain setting would you use to work with the ADC?
