Product specification

1 W BTL audio amplifier with digital volume control

TDA8551

Notes to the Characteristics

1. With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal

3. Output voltage in mute position is measured with an input of 1 V (RMS), including noise, in a bandwidth of 20 kHz.

4. Total gain setting at +20 dB.

5. The noise output voltage is measured at the output in a frequency band from 20 Hz to 20 kHz (unweighted), input

The ripple voltage is a sine wave with frequency of 1 kHz and an amplitude of 100 mV (RMS) is applied to the positive

supply rail.
