The thermal resistance θj−T of TA8220HQ 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.

Features
•  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= 0.30mVrms(typ.)
                (VCC= 13.2V, RL= 4Ω, GV= 50dB, Rg= 0Ω, BW = 20Hz~20kHz)
•  Built−in stand−by function (with (4)pin set at low, power is turned off.): ISB= 1µA (typ.)
•  Built−in output short detection circuit ((9)pin: Open collector)
•  Built−in output clip detection circuit ((1)pin: Open collector)
•  Built−in various protection circuits
   Protection circuits: Thermal shut down, Over voltage, Out→VCCshort, Out→GND short and
   Out−Out short.
•  Operating supply voltage: VCC= 9~18V
