Note 34. 0dB is the output level when a 1kHz 25% ~ 75% duty sibne wave is input.
Note 35. The frequency(20 k,100 k,150 kHz) is doubled in 128 fs(DSDSEL[1:0] bits = “01”), and it is four
times in 256 fs(DSDSEL[1:0] bits = “10”).

Note 36. The TESTE, TDMO, PSN, DIF0 and DIF1 pins have internal pull-down. The value of resistance
is 100 kohm(typical).Therefore the TESTE, TDMO, PSN, DIF0 and DIF1 pins are not included in
this specification.
