8 / 100 page  WM8953 Production Data w PD, January 2009, Rev 4.0 8 ELECTRICAL CHARACTERISTICS Test Conditions DCVDD = 1.8V, DBVDD = 3.3V, AVDD = 3.3V, TA = +25 oC, 1kHz signal, fs = 48kHz, PGA gain = 0dB, 24-bit audio data unless otherwise stated. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Analogue Input Pin Maximum Signal Levels (LIN1, LIN2, LIN3, LIN4, RIN1, RIN2, RIN3, RIN4) Single-ended PGA input on LIN1, LIN3, RIN1 or RIN3, output to INMIXL or INMIXR 1.0 0 Vrms dBV Maximum Full-Scale PGA Input Signal Level Note 1; Note 2; Note 3 Differential PGA input on LIN1/LIN2, LIN3/LIN4, RIN1/RIN2 or RIN3/RIN4, output to INMIXL or INMIXR 1.0 0 Vrms dBV Maximum Full-Scale Line Input Signal Level Note 1; Note 2; Note 3 Line input on LIN2, LIN4, RIN2 or RIN4 to INMIXL or INMIXR 1.0 0 Vrms dBV Notes 1. Maximum full scale signal changes in proportion to AVDD (AVDD/3.3). 2. When mixing input PGA outputs and line inputs, the total signal must not exceed 1Vrms (0dBV). 3. A 1.0Vrms differential signal equates to 0.5Vrms/-6dBV per input. |
