TA8215LQ Datasheet

18W BTL ×2CH Audio Power Amplifier


The thermal resistance θj−T of TA8215HQ and TA8215LQ 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.

•  High power
: POUT (1)= 18W (typ.) / channel
   (VCC= 14.4V, f = 1kHz, THD = 10%, RL= 4Ω)
 : POUT (2)= 15W (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, GV50dB, 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→VCCshort, Out→GND short and Out−Out  short. 
•  Operating supply voltage : VCC= 9~18V
