LC75051E
No.A0178-5/9
Analog Characteristics
Conditions: AVDD = 5V, BVDD = CVDD = 3.3V, DVDD = 1.8V, fs = 48kHz, audio signal frequency = 1kHz
Frequency bandwidth measured from A/D input to volume output: 10Hz to 20kHz, with a SANYO DSP evaluation
board used
Test circuit configured with circuits externally attached to LC75051E; tested with signals passed straight through the
DSP at room temperature using an audio analyzer (System 2) as the test device
