TB2921HQ - Maximum Power 50 W BTL X 4-ch Audio Power-IC

Description

1.

By means of controlling pin 4 (standby pin) to High and Low, the power supply can be set to ON and OFF.

Features

  • High power output : POUT MAX (1) = 50 W (typ. ) (VCC = 15.2 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 MAX (3) = 80 W (typ. ) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 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 = 0.01.

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. Additionally, high-side switch is built in. Weight: 7.7 g (typ.) Features • High power output : POUT MAX (1) = 50 W (typ.) (VCC = 15.2 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 MAX (3) = 80 W (typ.) (VCC = 14.
