Troubleshooting—What to Do When Things Go Wrong
Abstract
Troubleshooting op amp circuits sometimes involves correcting commonly made, simple mistakes. Checking power connections, enabling pin requirements, checking the DC operating point are the simplest. A designer oftentimes tries to get too much gain out of a single amplifier. Fixing noisy circuits is more involved. Noise conducted and radiated into and out of the circuit need to be checked. DC offset is also addressed.
