Conditions: Analog system: 5 V, digital system: 3.3 V, fs: 44.1 kHz, signal frequency: 1 kHz, from the analog source selector input to the
volume control circuit output.
Measurement band: 10 Hz to 20 kHz, using the SANYO-specified DSP evaluation board.
Test circuit: LC75010W external circuit structure with the DSP operating in through mode (4-bit shiftup), room temperature
Test equipment: Audio analyzer (Rohde & Schwarz UPD)
LC75010W Analog Characteristics
Note: THD+N shows the optimal characteristics for an input (1.5 Vp-p) that is 3 dB lower than the full-scale input level.
