TA7280,81P
5.8W Dual Audio Power Amplifier.
22W BTL Audio Power Amplifier.
The TA7280P, TA7281P are dual audio power amplifier for
consumer applications.
It is designed for high power, low distortion and low noise.
It also contains various kind of protectors.
It is suitable for car−audio power amplifier with high
performance.
The kinds of pin configuration are available: Normal (TA7280P)
and reverse (TA7281P) for easier layout design of PC−board when
used in BTL−stereo application.
Features
Weight: 4.04g (typ.)
· High power
: POUT (1) = 22W (typ.)
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω, BTL)
POUT (2) = 19W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω, BTL)
POUT (3) = 15W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 1%, RL = 4Ω, BTL)
POUT (4) = 5.8W (typ.) / ch
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω, DUAL)
· Low distortion
: THD (1) = 0.03% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 4W, RL = 4Ω, GV = 40dB, BTL)
THD (2) = 0.06% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 52dB, DUAL)
· Low noise
: VNO (1) = 0.14mVrms (typ.)
(VCC = 13.2V, RL = 4Ω, GV = 40dB, Rg = 0, DIN noise: DIN45405, BTL)
VNO (2) = 0.7mVrms (typ.)
(VCC = 13.2V, RL = 4Ω, GV = 52dB, Rg = 10kΩ, BW = 20Hz~20kHz, DUAL)
· Protector circuit
: Thermal shout down, Over voltage protection, Out−VCC short, Out−GND short and Out−Out short
protection.
· Operating supply voltage range
: VCC (opr) = 9~18V

The popping time at power supply on / off varies according to the rise and fall times.
The condition in which the power supply is rapidly and repeatedly mode on / off, that is, the condition in which
the charge is made on the external capacitor of IC is different from the conditions shown in (Fig. 5) and (Fig. 6) .
