Description

Max Power 37 W BTL × 4CH Audio Power IC

The TA8259H is 4 ch BTL audio power amplifier for car audio application.
This IC can generate more high power: POUT MAX = 37 W as it is included the pure complementary PNP and NPN transistor output stage. It is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in Stand-by Function, Muting Function, Clip detector, and diagnosis 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 use.

Features

     (VCC = 13.7 V, JEITA max, RL = 4 Ω)
   : POUT (1) = 24 W (typ.)
     (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
   : POUT (2) = 21 W (typ.)
     (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
• Built-in clip detector & diagnosis circuit. (pin 25)
• Low distortion ratio
   : THD = 0.02% (typ.)
     (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)
• Low noise
   : VNO = 0.16 mVrms (typ.)
     (VCC = 13.2 V, Rg = 0 Ω, GV = 34dB, BW = 20 Hz~20 kHz)
• Built-in stand-by switch function (pin 2)
