TB2921HQ - Maximum Power 50 W BTL X 4-ch Audio Power-IC
is made only on the single channel.) 1.
Standby SW Function (pin 4) By means of controlling pin 4 (standby pin) to High and Low, the power supply can be set to ON and OFF.
The threshold voltage of pin 4 is set at about 3VBE (typ.), and the power supply current is about 2 µA (typ.) in the standby st
TB2921HQ TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic TB2921HQ (preliminary) Maximum Power 50 W BTL × 4-ch Audio Power IC The TB2921HQ is 4-ch BTL audio amplifier for car audio applications.
This IC can generate higher power: POUT MAX =50 W as it includes the pure complementary P-ch and N-ch DMOS output stage.
It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors.
