Electrical characteristics

3.1

Electrical characteristic curves

The graphs shown in this section use the following abbreviations.

● RL+ 15 µH or 30 µH = pure resistor + very low series resistance inductor.

● Filter = LC output filter (1 µF+ 30 µH for 4 Ω and 0.5 µF+15 µH for 8 Ω).

All measurements are done with CSL= CSR=1 µF and CS = 100 nF (see Figure 2), except

for the PSRR where CSL, CSR is removed (see Figure 3).
