The thermal resistance θj−T of TA8210AHQ, TA8210ALQ package designed for low thermal resistance, has a 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.
In addition, the functions of stand−by and muting, and a variety of protection circuits are involved.
Features
• Low thermal resistance
: θj−T = 1.5°C / W (infinite heat sink)
• High power
: POUT (1) = 22W (typ.) / channel
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω)
POUT (2) = 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 pin(4) set at low, power is turned off.): ISB = 1μA (typ.)
• Built−in muting function (with pin(1) set at low, power is turned off.): V (mute) = 1V (typ.)
• Built−in various protection circuits Protection circuits: Thermal shut down, Over voltage, Out→VCC short, Out→GND short and Out−Out short.
• Operating supply voltage: VCC = 9~18V
