TDA8767
Notes to the characteristics
1.
The
3 dB (or
1 dB) analog bandwidth is determined by the 3 dB (or 1 dB) reduction in the reconstructed output,
the input being a full-scale sine wave.
2.
THD (total harmonic distortion) is obtained with the addition of the first five harmonics:
(2nd)2
+
+
+
F being the fundamental harmonic referenced at 0 dB for a full-scale sine wave input.
The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale
input (square wave signal) in order to sample the signal and obtain correct output data (see Fig.5).
Output data acquisition: the output data is available after the maximum delay of t
d
.
