TA8260AH

Max Power 40 W BTL × 4CH Audio Power IC

TA8260AH

The TA8260AH 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

Weight: 9.8 g (typ.)

· High power

: POUT MAX (1) = 40 W (typ.)

(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)

: POUT MAX (2) = 37 W (typ.)

(VCC = 13.7 V, f = 1 kHz, JEITA 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)

· Built-in clip detector & diagnosis circuit. (pin 3)

· 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 AUX. amplifier from single input (pin 16) to 2 channels output ; OUT1 and 4

· Built-in junction temperature detection circuit (pin 23)

: Pin 23 DC voltage rises at about +5 mV/°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) = 9~18 V
