TB2903HQ - Maximum Power 47W BTL x 4-Ch Audio Power-IC

General Description

is made only on the single channel.) 1.

This IC has no NF (negative feedback) Pins.

Therefore, the voltage gain can not be adjusted, but it makes the device a space and total costs saver.

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 =.

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.) 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.
