Characterization curves

Unless otherwise stated, measurements were made under the following conditions:

Note: Maximum output power must be derated according to case temperature.

Stereo configuration

The following characterization curves were made using the TDA7492E demonstration

board (Figure 7: "Application circuit"). The characterization curves were made under the

following test conditions:

= 6 Ω, Rosc = 33 kΩ, Cosc = 100 nF, Gain = 20.8 dB and Tamb = 25°C

unless otherwise specified.
