TA8238K

The TA8238K is a kind of 7.3W*2CHdual audio power amplifier for consumer application. It contains various kind of protectors and the function of stand-by switch.

The features of TA8238K can be summarized as (1)output power: POUT (1)=7.3W(typ.) (VCC=13.2V, f=1KHz, THD= 10%, RL= 2) : POUT =6.4W (VCC= 14.4V, f=1KHz, THD= 10%, RL= 4): POUT =5.3W(VCC=13.2V, f==1KHz, THD= 10%, RL= 4); (2)total harmonic distortion: THD=0.1% (VCC=13.2V, f=1kHz, POUT=1W, RL=4); (3)built in stand-by switch function: I STBY=1A (with Pin set at High, power is turned ON.); (4)built in junction temperature detection function: 10mV/°C; (5)built in various protection circuits: over voltage, thermal shut down out to GND, out to VCC; (6)operating supply voltage: VCC(opt) =6~18V.

The absolute maximum ratings of TA8238K are (1)peak supply voltage VCC(surge): 50V; (2)DC supply voltage VCC(DC): 20V; (3)operating supply voltage VCC(opr): 18V; (4)output current (peak) lOpeak: 4.5A; (5)power dissipation PD: 15W; (6)operating temperature Topr: -30~85°C; (7)storage temperature Tstg: -55~150°C.
