    Part Number: LM4675 We have a LM4675 design that we had TI review. So far we can't get any audio out of it. I tied it's shutdown pin to VDD and hooked up a signal generator at the speaker_mono signal. I'm putting in a 1Vpp 1kHz sine wave. If I measure…

    We have some issue. We connect the shutdown pin to VCC by 10K Ohm. When we remove the power maybe 2~3 second that depend on Vcc Cap. If they VCC voltage drop above 0.2~0.3V then plug in again, we would easy to duplicate this issue. If we only short the…
