TDA7535

4/9

Note1:

It is the ratio between the maximum input signal and the integration of the in-band noise after deducing the power of signal funda-

mental. It depends on the input signal amplitude. In this case 0dB means full scale digital, 1kHz frequency used.

Note 2:

It is the ratio of the rms value of the signal fundamental component at 0dB (full scale digital) to the rms value of all of the harmonic

components in the band.

Note 3:

measured using the SNR at -60dB input signal, with 60dB added to compensate for small input signal.

Note 4:

Left channel on with 0dB/1kHz input signal, Right channel on with DC input signal.

Note 5

by correlation to beuch results. ATE limits are 60dB

Note 6

by correlation to beuch results. ATE limits are 80dB
