BD8203EFV
No.10011EAT02
●Description
BD8203EFV is 5ch system motor driver for CD/DVD. A linear BTL method can be adopted for all 5ch and a low noise be
designed. Built-in 5V regulator, a changeable regulator, and a general-purpose operational amplifier , and it is the best for the
system design for car audio.
●Features
1) Linear BTL method is adopted for the actuator driver and the DC motor driver and a low noise is achieved.
2) Loading driver 1CH
3) Built-in regulator 2CH (1ch output changeability)
4) MUTE function and Standby function
5) Built-in general-purpose operational amplifier 1CH
6) Built-in internal operational amplifier for the voltage detection between driver outputs and for Vc standard
●Applications
