TA8255AHQ 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.The voltage gain of amp.1: GV1 = 0 dB The voltage gain of amp.2A, B: GV2 = 28 dB The voltage gain of BTL connection: GV (BTL) = 6 dB Therefore, the total voltage gain is decided by expression below.GV = GV1 + GV2 + GV (BTL) = 0 + 28 + 6 = 34 dB 2. Stand by SW function By mea

Features

Weight: 9.8g (typ. ).
High power : POUT (max) = 22 W (typ. ) (VCC = 13.7 V, f = 1 kHz, RL = 4 Ω) : POUT (1) = 17 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 14 W (typ. ) (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 = 3 W, RL = 4 Ω).
Low noise : VNO = 0.10 mVrms (typ. ) (VCC = 13.2 V, Rg = 0 Ω, GV = 34 dB, BW = 20~20 kHz).
