TS4962M
In the graphs that follow, the following abbreviations are used:
● RL + 15µH or 30µH = pure resistor+ very low series resistance inductor
● Filter = LC output filter (1µF+30µH for 4Ω and 0.5µF+60µH for 8Ω)
● All measurements done with Cs1=1µF and Cs2=100nF except for PSRR where Cs1 is
removed.
