TB2902HQ Product details

Description

is made referring 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 (except by software).However, this feature makes possible space and cost saving.Amp.2A Amp.1 Input www.DataSheet4U.com Amp.2B Figure 1 Block Diagram The amplifier gain, GV = 26dB, is calculated using the expression below: The voltage gain of amp.1: GV1 = 0dB The voltage gain of amp.2A, B: GV2 = 20dB The voltage gain of BT

Features

High power output : POUT MAX (1) = 41 W (typ. ) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 37 W (typ. ) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (3) = 70 W (typ. ) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω) : POUT (1) = 27 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) : POUT (3) = 45 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 Ω) Low distortion ratio: THD =.
