com TA8251AHQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8251AHQ Max Power 30W BTL × 4ch Audio Power IC The TA8251AHQ is 4ch BTL audio power amplifier for consumer application.
It is designed low distortion ratio for 4ch BTL audio power amplifier, built−in stand−by function, muting function and junction temperature detection circuit.
Additionally, the AUX.
amplifier is built−in, 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 = 4Ω) : POUT (1) = 21W (typ.
) (VCC = 14.
4V, f = 1kHz, THD = 10%, RL = 4Ω) Weight: 9.
8g (typ.
) • Low distortion ratio : THD = 0.
02% (typ.
) (VCC = 13.
2V, f = 1kHz, POUT = 3W, RL = 4Ω) • Low noise : VNO = 0.
10mVrms (typ.
) (VCC = 13.
2V, Rg = 0Ω, GV = 34dB, BW = 20~20kHz) • • • • • • Built−in stand−by switch function (pin(2)) Built−in muting function (pin(1), (25)) Built−in AUX.
amplifier from single input to 2 channels output (pin(16)) Built−in junction temperature detection circuit (pin(24)) : Pin(24) DC voltage rises at about +10mV / °C in proportion to junction temperature.
Built−in 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 ww.
