Hello everyone,
I wanted some feedbacks/suggestions/corrections/alternatives, or whatever it might be that would help me with my project.
My project is to build a speaker board.
I know the basic gist of what to do, but what I am having trouble with is choosing the right chips!
power supplies i have are : 5v and 3.3v
I got 8 bits in parallel, V_H = 3.3V
frequency range : 250Hz to 4.5 Khz
For the DAC I found two chips, AD7801 and AD7302
For the OPamp, I found LM4990 (If you know any other op amp chip that works in +5v range please do let me know, also I want an output power of 2W)
For Speaker I found CMS0361KLX (Link: http://products.cui.com/CUI_CMS0361KLX_Datasheet.pdf?fileID=1113)
I also found another speaker AS06608PS-WR-R but this needs about 4W of power so i would have to change the op amp.
I would really appreciate if anyone can tell me if i got the chips right.. Or if anyone could suggest different chips. This is a very small projects, i do not need high performance chips, cheaper the better. All I need is for the speaker to output the sound in the given frequency range and a potentiometer to control the volume.
Any help appreciated!
Thank you so much!
