Selecting IC chips for MSP430 design

[Hyunsoo166]

first of all, i'm sorry to my unskilled Eng grammar.

i'm using MSP430 (ti) mcu,

and i developed dc-dc converter circuits and etc(led, buzzer...) for my device.

now i want to make 1.3V ac signal which frequency is 10kHz ~ 100kHz.


i don't know which ic chip can be used.

plz help me ....

Use Digital to Analog Converter..

Hello!

If it's only a matter of having a buzzer signal, you don't need an ADC, you can put it directly
at at GPIO output. At least if it's a piezo device, it will work.
But I don't understand the DCDC stuff. Is there any relation with the buzzer?

Hi,

* Waveform? (precision)
* current?
* frequency: You need to adjust? or is any frequency between 10k and 100kHz good?
If adjustable: what frequency steps?
