... Philips Semiconductors Speech and listening-in IC Dynamic limiter/loudspeaker amplifier disabling; pin DLL/DIL The dynamic limiter in the loudspeaker channel of the TEA1096/TEA1096A prevents clipping of the loudspeaker output stage and protects the functioning of the circuit when low supply conditions are detected. Hard clipping of the loudspeaker output stage is prevented by rapidly reducing the gain when the output stage starts to saturate ...
