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.
