PCM1754-Q1: VCOM cap

Part Number: PCM1754-Q1

Hi team,

Regarding to the bypass capacitor of PCM1754-Q1, it is described as

"Proper power supply bypassing is shown in Figure 30. The 10-μF capacitors should be tantalum or aluminum electrolytic."

Is it OK to use MLCC X7R 10uF capacitor for VCOM instead of tantalum or aluminum electrolytic?

regards,

    Hi Tsuji,

    Yes, you can use ceramic caps for the VCOM and supply pins.  When this datasheet was originally written, there were less low-ESR ceramics on the market.  Now there are many very good ceramics for this application.

    Thanks,

    Paul
