TS4962 Electrical characteristics
Doc ID 10968 Rev 8 19/44
3.1 Electrical characteristics curves
The graphs shown in this section use the following abbreviations.
● R
L
+ 15 μH or 30 μH = pure resistor + very low series resistance inductor
● Filter = LC output filter (1 µF + 30 µH for 4 Ω and 0. 5µF + 60 µH for 8 Ω)
All measurements are done with C
S1
= 1 µF and C
S2
= 100 nF (see Figure 2), except for the
PSRR where C
S1
is removed (see Figure 3).
