TA8210AH - 20W BTL × 2ch Audio Power Amplifier

20W BTL × 2ch Audio Power Amplifier 

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 = 4?) 

 POUT (2) = 19W (typ.) / channel 

 (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4?) 

• Low distortion ratio: THD = 0.04% (typ.) (VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4?, GV = 50dB) 

• Low noise: VNO = 0.30mVrms (typ.) (VCC = 13.2V, RL = 4?, GV 50dB, Rg = 0?, 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
