TB2905HQ - Low-Frequency Power Amplifier IC

General Description

1.

The TB2905HQ has no NF (negative feedback) pins.

Therefore, the voltage gain (GV) is determined within the IC.

Key Features

  • High output power : 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 Pout MAX (3) = 80 W (typ. ) (VCC = 14.4V, 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) : POUT (3) = 55 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%,RL = 2 Ω) Low distortion ratio : TH.

ency, Low-Frequency Power Amplifier IC Maximum Power: 47 W × 4 Channels The TB2905HQ is a high-efficiency class KB power amplifier IC developed for car audio applications that incorporates four BTL amplifier channels. It employs a pure complementary DMOS output stage www.DataSheet4U.com consisting of P-ch upper and N-ch lower sections, offering a maximum output power (POUT) of 47 W. Class KB (keyed BTL) amplifiers exhibit less than half the heat generation of comparable class AB solutions under normal operating conditions. Therefore, it is possible to design a smaller Weight: 7.7 g (typ.) heatsink and maintain lower intern
