Preliminary TCB503HQ CDMOS Linear Integrated Circuit Silicon Monolithic TCB503HQ
Maximum Power 50 W BTL × 4ch Audio Power Amp IC 1. Description The TCB503HQ is a power IC with built-in four-channel BTL
amplifier developed for car audio application. The maximum
output power POUT is 50 W using a pure complementary
P-ch and N-ch DMOS output stage.
In addition, a standby switch, a mute function, output DC offset
voltage detection, various protection features are included. 2. Applications
