Part Number: LM48560
Hi Team,1)Could you tell me recommended piezo driver for the following piezo speaker?> PHUA3030-049B-00-000I found LM48560 and LM48580. Are these recommended device?2)My customer also looking for piezo haptics driver for the following piezo actuators.> PHUA8060-35A-33-000> PHUA3015-30A-21-000Could you tell me recommended devices?Best Regards,Yaita
Do you have the capacitance value for each device? Usually, our piezo drivers are selected depending of the piezo capacitance. If you could get this value, it would be helpful to recommend a piezo driver for you. Otherwise, I could only say that the DRV2700 is the piezo driver with more capabilities an wider accepted capacitance range.

Hi Luis-san,1)> PHUA3030-049B-00-000capacitance value: 4.8uF±15%https://media.digikey.com/pdf/Data%20Sheets/TDK%20PDFs/PiezoListen_DS.pdfThe datasheet shows operating voltage range is 0±12V, is it possible for DRV2700 to drive the piezo speaker?DRV2700 datasheet shows recommended VBST is 15V(min).2)> PHUA8060-35A-33-000> PHUA3015-30A-21-000Regarding two device above, I couldn't find the capacitance value in datahsheet.https://product.tdk.com/info/en/catalog/datasheets/piezohapt_commercial_phu_en.pdfShould we ask the capacitance to TDK?Best Regards,Yaita
In reply to K.Yaita:
1) Unfortunately, the capacitance value of this load is too high for our piezo drivers. I would say that probably the LM48580 would be the best option, but I don't think it will have good performance due to the high capacitance level.
2) For these piezo actuators, could you get the capacitance value, please? Otherwise, we cannot suggest a piezo driver.
