Zero-Drift Precision Op Amps: Advantages and Limitations of the Chopper-Stabilized Architecture
specialized op amps designed for applications that require high output accuracy due to small differential voltages. Not only do they feature low input offset voltage, but they also have high CMRR, high PSRR, high open loop gain, and low drift over temperature and time. These features make them ideal for applications such as low−side current sensing and sensor interface, particularly with very small differential signals.

Capacitive Loads and Phase Margin
Driving a capacitive load with an op amp can be tricky. If the load capacitance is too high, this can cause instability, making the op amp output oscillate. Having adequate phase margin is essential for stability. As load capacitance increases, phase margin decreases. If you are seeing an op amp output oscillate, the first thing to look at is the load.
