OPA333 has three PSRR parameters
1、Power supply rejection ratio : 1uV/V;
2、Long-term stability : 1uV;
3、Channel separation, DC :0.1uV/V.
My understanding
1. For example, if the input voltage is 5V, is the output ripple 5uV?
2. The long-term stable parameter means that, no matter how big the power supply ripple, can it maintain a 1uV ripple with this op amp?
3. How to understand channel separation, does the ripple rejection ratio not refer to the AC parameters?
