6 / 18 page 1998 Feb 23 6 NXP Semiconductors Product specification 3 W mono BTL audio amplifier with DC volume control TDA7056AT CHARACTERISTICS VP =12V; VDC = 1.4 V; f = 1 kHz; RL =16 Ω; Tamb =25 °C; unless otherwise specified (see Fig.14). Notes 1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being equal to the DC output offset voltage divided by RL. 2. The noise output voltage (Vn(o)(rms)) at f = 500 kHz, is measured with Rs =0 Ω and B = 5 kHz. 3. The ripple rejection is measured with Rs =0 Ω and f = 100 Hz to 10 kHz. The ripple voltage (Vripple =200 mV RMS) is applied to the positive supply rail. 4. The noise output voltage (Vn(o)(rms)) is measured with Rs =5kΩ unweighted. SYMBOL PARAMETER CONDITIONS MIN. TYP.
