BA5826FP-E2 ROHM

1/5 Structure : Silicon Monolithic Integrated Circuit Product Name : Power Driver For Compact Disc Players Device Name : BA5826FP Features : 4-ch BTL driver Use of an HSOP28 power package can achieve downsizing of the set. Gain can be controlled by attaching an external resistance. A built-in thermal shutdown circuit installed. A built-in 3.3V regulator installed. (External PNP Tr must be installed.) A built-in general operational amplifier installed. A built-in 2.7V reset circuit installed. Using an external capacitor, the reset delay time can be changed.
