TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7280P,TA7281P
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 caraudio power amplifier with high
performance.
The kinds of pin configuration are available: Normal (TA7280P)
and reverse (TA7281P) for easier layout design of PCboard when
used in BTLstereo application.
Features
Weight: 4.04g (typ.)
· High power
: POUT (1) = 22W (typ.)
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4, BTL)
POUT (2) = 19W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4, BTL)
POUT (3) = 15W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 1%, RL = 4, BTL)
POUT (4) = 5.8W (typ.) / ch
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4, DUAL)
· Low distortion
: THD (1) = 0.03% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 4W, RL = 4, GV = 40dB, BTL)
THD (2) = 0.06% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4, GV = 52dB, DUAL)
· Low noise
: VNO (1) = 0.14mVrms (typ.)
(VCC = 13.2V, RL = 4, GV = 40dB, Rg = 0, DIN noise: DIN45405, BTL)
VNO (2) = 0.7mVrms (typ.)
(VCC = 13.2V, RL = 4, GV = 52dB, Rg = 10k, BW = 20Hz~20kHz, DUAL)
· Protector circuit
: Thermal shout down, Over voltage protection, OutVCC short, OutGND short and OutOut short
protection.
· Operating supply voltage range
: VCC (opr) = 9~18V

TA7280,81P
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) .
