POP-AND-CLICK SUPPRESSION
Pop-and-Click is the noise which happens with
amplifier start and shutdown. IS31AP2036 integrates
Pop-and-Click suppression circuitry to decrease noise
effectively.
THERMAL AGC
IS31AP2036 adopts Thermal AGC techniques which
adjust output gain automatically by IC junction
temperature to decrease power dissipation. When the
junction temperature is over threshold value (150°C),
the IC will start up automatic control circuit to decrease
output gain. Thus, power dissipation will be decreased
and junction temperature stops rising. When the
junction temperature falls down to the operating
temperature (130°C), automatic control circuit will
resume output gain. If the junction temperature
continues rising to the OVP threshold (160°C), IC will
shut down untill junction temperature comes back to
130°C.
OVER CURRENT PROTECTION
IS31AP2036 integrates over current protection
function. IC will shut down when over current is
detected to prevent IC damage. As clean up
short-circuit, IC will resume operation without restart.
