TB2904HQ Product details

Description

is made only on the single channel) 1. Voltage Gain Adjustment 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.Amp.2A Amp.1 Input Amp.2B Figure 1 Block Diagram The voltage gain of amp.1 : GV1 = 0dB The voltage gain of amp.2A, B : GV2 = 20dB The voltage gain of BTL connection : GV (BTL) = 6dB Therefore, the total voltage gain is decided by expression below.GV = GV1 + GV2 + GV (BTL) = 0 + 20

Features

High power output : POUT MAX (1) = 43 W (typ. ) P (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 39 W (typ. ) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT (1) = 26 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 23 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 = 90 µVrms (typ. ) (VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL =.
