NOTES:
1. Package parasitic capacitance amounts to about 0.2pF.
2. PSRR is output referenced and is circuit board layout dependent at higher frequencies. For best performance use RF filter in V_CC line.
3. Guaranteed by linearity and over load tests.
4. t_R defined as 20-80% rise time. It is guaranteed by -3dB bandwidth test.
5. As in all high frequency circuits, a supply bypass capacitor should be located as close to the part as possible.
