TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8251AH
Max Power 30W BTL × 4ch Audio Power IC
The TA8251AH is 4ch BTL audio power amplifier for consumer
application.
It is designed low distortion ratio for 4ch BTL audio power
amplifier, builtin standby function, muting function and
junction temperature detection circuit. Additionally, the AUX.
amplifier is builtin, it can make the beep signal etc. Output to 2
channels (out1 and 4).
It contains various kind of protectors for car audio.
Features
High power
: POUT (max) = 30W (typ.)
(VCC = 13.7V, f = 1kHz, RL = 4)
: POUT (1) = 21W (typ.)
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4)
: POUT (2) = 18W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4)
Low distortion ratio
: THD = 0.02% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 3W, RL = 4)
Low noise
: VNO = 0.10mVrms (typ.)
(VCC = 13.2V, Rg = 0, GV = 34dB, BW = 20~20kHz)
Builtin standby switch function (pin(2))
Builtin muting function (pin(1), (25))
Builtin AUX. amplifier from single input to 2 channels output (pin(16))
Builtin junction temperature detection circuit (pin(24))
: Pin(24) DC voltage rises at about +10mV / °C in proportion to junction temperature.
Builtin various protection circuit
: Thermal shut down, Over voltage, Out to GND, Out to VCC, Out to Out short
Operating supply voltage
: VCC (opr) = 9~18V
Weight: 9.8g (typ.)
