Hi，

I have a question when i use the EVM430-FR6047 and TIDA-01486，

1，how to generate - 15V voltage？and guarantee the driving ability of -15V？

2，how to chose the voltage of VBIAS？can i keep it float？

Hello,

For the TIDA-01486 -15V are supplied with an external power supplier.

You cannot keep the Vbias floating. Either you provide it externally for example with an external power supply or internally if you have connected the TIDA-01486 to the MSP430 EVM. In this case you have to place a jumper between pin 2 and 3 of the connector J6.

Best regards

Giovanni

Hi，

Can you recommend an IC to supply the voltage of -15V？ What i found can only supply 100mA current，can not drive the PZT。

Thank you

Hi,

What is the needed output current?

Thanks

Hi，

I just want to drive 1Mhz ±12V PZT，what can be used in TIDA-01486，I‘m not sure what output current is needed，can you recommend me some usual IC can output -15V？

Thanks

Hi,

What is going to be the input voltage of your application?

Thanks
