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
