TB2903HQ Datasheet Maximum Power 47w Btl X 4-ch Audio Power-ic

Manufacturer: Toshiba

Overview: TB2903HQ TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2903HQ Maximum Power 47 W BTL × 4-ch Audio Power IC The TB2903HQ is 4-ch BTL audio amplifier for car audio applications. This IC can generate higher power: POUT MAX = 47 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. Additionally, Off-set detector is built in. Weight: 7.7 g (typ.

Key Features

  • High power output : POUT MAX (1) = 47 W (typ. ) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 43 W (typ. ) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT (1) = 29 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 25 W (typ. ) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω).
  • Low distortion ratio: THD = 0.015% (typ. ) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω) Low noise: VNO =.
