The BA6797FP and BA6797FM are 4-channel BTL power drivers for CD players and each have an internal 5V regulator
(requires attached PNP transistor). Because the input stage of each driver channel connects to an operational amplifier,
and there are both positive and negative input pins, making these ICs adaptable for a wide range of inputs and greatly
simplify filter configuration. In addition, the internal level shifting circuit reduces the number of external components.
FApplications
CD players, CD-ROM drives and other optical disc devices
FFeatures
1) 4-channel BTL driver in a HSOP 28-pin power pack-
2) Wide dynamic range.
3) Internal thermal shutdown circuit.

... Optical disc ICs FApplication example FOperation notes (1) The BA6797FP and BA6797FM have an internal thermal shutdown circuit. Output current is muted when the chip temperature exceeds 175_C (typically). (2) If the mute pin (pin 9) voltage is opened or lowered below 0.5V, the output current will be muted. Pin 15 should be pulled up above 2 ...
