Das Startup kommt m.E. hiervon:
"During startup,
or power-up, the input amplifiers are muted and an
internal loop sets the modulator bias voltages to the correct
levels, preventing clicks and pops when the Hbridge
is subsequently enabled. Following startup, a
soft-start function gradually unmutes the input amplifiers."
Die gezeigten Messungen wurden bei einem funktionieren Verstärker gemessen.
Der Reliabilty Test sagt:
"E.S.D. and Latch-Up Testing
The AU19-3 die type has been found to have all pins able to withstand a transient pulse of ±800V, per Mil-
Std-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device
withstands a current of ±250mA."
