TA8254BHQ Product details

Description

is made only on the single channel) 1. Voltage Gain Adjustment This IC has no NF (negative feedback) terminals.Therefore, the voltage gain can’t 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 BLT Connection: GV (BTL) = 6dB Therefore, the total voltage gain is decided by expression below.GV = GV1 + GV2 + GV (BTL) = 0 + 20 +

Features

High power : POUT (1) = 45 W (typ. ) /channel (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 Ω) : POUT (2) = 35 W (typ. ) /channel (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 2 Ω) : POUT (3) = 21 W (typ. ) /channel (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω) Low distortion ratio : THD = 0.02% (typ. ) (VCC = 13.2 V, f = 1 kHz, POUT = 10 W, RL = 4 Ω) Low noise : VNO = 0.10 mVrms (typ. ) (VCC = 13.2 V, RL = 4 Ω, Rg = 0 Ω , BW = 20 Hz to 20 kHz) Built-in stand-by function : (with pin set at LOW,.
