Product specification

2 x 1.4 W BTL audio amplifiers with digital

volume control and headphone sensing

TDA8552T; TDA8552TS

(maximum gain = 20 dB); according to Fig.4.

Notes

1. Volume setting at maximum.

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

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

positive supply rail, gain select pin is LOW (0 V).

frequency of 1 kHz. The output level in the operating single-ended channel (OUT+) is set at 2 V (RMS).
