Electrical characteristics

3.1

Electrical characteristics 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. 5µF + 60 µH for 8 Ω)

All measurements are done with CS1 = 1 µF and CS2 = 100 nF (see Figure 2), except for the

PSRR where CS1 is removed (see Figure 3).
