Optical disc ICs
4-channel BTL driver for CD players
BA6797FP / BA6797FM
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-
age, ideal for application miniaturization.
2) Wide dynamic range.
3) Internal thermal shutdown circuit.
4) Internal level shifting circuit reduces the number of
external components.
5) Dual positive and negative input pins, for adaptability
for a wide range of inputs (including negative phase
input). Also simplifies filter configuration.
