5 channel BTL Driver for CD
BA5814FM
Description
The BA5814FM is 5ch BTL driver for CD applications.
Separating Vcc into PREVCC and POWTr
(Power divides into CH1/2 and CH4/5) can make for
better power efficiency.
Dimension (Units : mm)
Features
1) Small surface mounting power package HSOP-M28
2) Internal thermal shut down circuit
3) Wide dynamic range
4) Built-in variable 2 channel regulator
(External PNPTr is necessary.)
