TA8261AH
Max Power 40 W BTL × 4CH Audio Power IC
TA8261AH
The TA8261AH is 4 ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: POUT MAX = 40 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
· High power
: POUT MAX (1) = 40 W (typ.)
(VCC = 14.4 V, f = 1 kHz, EIAJ max, RL = 4 Ω)
: POUT MAX (2) = 37 W (typ.)
(VCC = 13.7 V, f = 1 kHz, EIAJ max, RL = 4 Ω)
: POUT (1) = 27 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
: POUT (2) = 22 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
Weight: 9.8 g (typ.)

· Built-in AUX. amplifier from single input to 2 channels output (pin 16)
· Low distortion ratio
: THD = 0.02% (typ.)
(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)
· Low noise
: VNO = 0.10 mVrms (typ.)
(VCC = 13.2 V, Rg = 0 Ω, GV = 26dB, BW = 20 Hz~20 kHz)
· Built-in stand-by switch function (pin 2)
· Built-in muting function (pin 24)
· 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) = 9~18 V

3. Muting function (pin 24)
By means of controlling pin 24 less than 0.5 V, it can make the audio muting condition.
The muting time constant is decided by R1 and C4 and these parts is related the pop noise at power
ON/OFF.The series resistance; R1 must be set up less than 15 kΩ, we recommend 10 kΩ.
The muting function have to be controlled by a transistor, FET and µ-COM port which has IMUTE ≥ 250 µA
ability.
Terminal 24 must not be pulled up and it shall be controlled by OPEN/LOW.

4. AUX. input (pin 16)
The pin 16 is for input terminal of AUX. amplifier.
The total gain is 0dB by using of AUX. amplifier.
Therefore, the µ-COM can directly drive the AUX. amplifier.
BEEP sound or voice synthesizer signal can be input to pin 16 directly.
