Abstract
A method for detecting a fault condition of an operational amplifier of an integrated circuit during operation includes operating an integrated circuit which includes an operational amplifier (op-amp) having a V+ input, a V− input and an op-amp output and an on-line fault detector electrically coupled to the V+ input and the V− input of the op-amp of the on-line fault detector, monitoring an operation of the op-amp with the on-line fault detector, and developing a fault signal at a fault detector output if the op-amp is in a fault condition as determined by the on-line fault detector.
