Dual Audio Power Amplifier 6 W × 2 Ch

TA8246AH is dual power amplifier for Consumer applications. This IC provides an output power of 6 watts per channel (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 Ω). It is suitable for power amplifier of TV and home Stereo.  Circuit diagram:

30W BTL × 2ch Audio Power Amplifier

General Description: The thermal resistance θj−T of TA8220H package designed for low thermal resistance, has high efficiency of heat radiation. The temperature rise of chip can be reduced, and the influence from the degradation of the features due to the temperature rise at the high output can also be reduced. This stereo audio power IC, designed for car audio use, has two  built−in channels to reduce the characteristic difference between L and R channels. It also contains output short detection circuit, output clip detection and various kind of protection. 
Low thermal resistance: θj−T = 1.5°C / W (infinite heat sink)  High power: POUT (1) = 30W (typ.) / channel (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2Ω) : POUT (2) = 26W (typ.) / channel (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2Ω) : POUT (3) = 19W (typ.) / channel (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)  Low distortion ratio: THD = 0.04% (typ.) (VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 50dB)  Low noise: VNO = …
