LMC6042IN/NOPB Working Principle

The LMC6042IN/NOPB consists of two operational amplifiers, each with a gain-setting resistor and a common feedback resistor. The input signals are applied to the non-inverting (or inverting) inputs of the op-amps, and the output is taken from the outputs of the op-amps. The gain is set by the ratio of the gain-setting resistor and the feedback resistor. The device also contains a chopper-stabilization circuit, which ensures low offset and miniscule drift. The chopper-stabilization circuit operates by alternating the bias current to the op-amps. This reduces the DC offset of the amplifiers, enabling them to maintain high precision over long periods of time.
