Max Power 45 W BTL × 2 ch Audio Power IC

The TA8254BHQ is BTL stereo audio power amplifier for car audio application, especially for 2 Ω load impedance. It is built-in Stand-by Function, Muting Function, diagnosis circuit output clipping detector and various kind of protections.

Features:
  • High power
    - POUT (1) = 45 W (typ.) /channel
    (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 Ω)
    -  POUT (2) = 35 W (typ.) /channel
    (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 2 Ω)
    -  POUT (3) = 21 W (typ.) /channel
    (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
  • Low distortion ratio
    - THD = 0.02% (typ.)
    (VCC = 13.2 V, f = 1 kHz, POUT = 10 W, RL = 4 Ω)
  • Low noise
    - VNO = 0.10 mVrms (typ.)
    (VCC = 13.2 V, RL = 4 Ω, Rg = 0 Ω, BW = 20 Hz to 20 kHz)
  • Built-in stand-by function :  (with pin set at LOW, power is turned OFF) ISB = 1 μA (typ.)
  • Built-in output clipping detection and diagnosis circuit :  (open collector (active LOW))
  • Built-in various protection circuits : Thermal shut down, over voltage, OUT → VCC short, OUT → GND short and OUT-OUT short.
  • Operating supply voltage: VCC (opr) = 9 to 18 V
