... Optical disc ICs FOperation notes (1) The BA6397FP has an internal thermal shutdown circuit. Output current is muted when the chip tempera- ture exceeds 175_C (typically). (2) If the mute pin (pin 7) voltage is opened or lowered below 0.5V, the output current will be muted. Pin 7 should be pulled up above 2.0V during normal use. ...
