how can I wire a DS1809 digital pot to a AN7510 stereo amp ? Answered
How can I wire a DS1809 digital pot to a AN7510 stereo amp ? I am trying to boost a left and a right audio signal to produce fairly significant sound through 2x 8ohm speakers. i currently have it running off of 2x LM386's and a wheel potentiometer with 5 pins. as you know, LM386's dont have the best sound. and who likes wheel pots and trimmers when you can use tact switches. so heres where I am.(Datasheets can be accessed by clicking on the IC's)
o This is to run sound directly from an N64 game console being converted to a portable, to a pair of 8 ohm speakers approx 1".
o I want to be able to have a P.B. volume up and down, and mute if possible.
o Power is 14.8 VDC, or 5VDC
o Was going to follow this schematic and use a TDA7053A Stereo Amp(By Phillips), with a DS1669 Digital Pot (By Dallas), but the IC's are hard
to get and pricey.
o Want use a AN7510 Stereo Amp w/ Volume control (By Panasonic) and a DS1809 Digital Pot w/ Storage(By Dallas)
PROBLEMS THUS FAR:
o Whilst designing the circuit i couldn't figure out where to connect PIN 6 on the Dallastat to on the amp. it claims it has volume control.???
o I also dont know how to use the MUTE PIN feature or the STANDBY PIN feature. Are the Tact Switches???
I am still just a begginner at low voltage electronics. I have done a lot of reading and tinkering. I do understand the basic principles of electricity, ohms law, working with resistors, LEDS, and the basic functionality of capacitors, transistors, and the like. I am a quick study so if anyone can help me to make this work and understand why it will work, that would be great. I have attached some pictures to help my cause and will supply whatever other information may be needed to accomplish this. The first picture is the schematic that gave me the idea, the second is a perfboard layout i was working on for this idea. Thankyou all in advance for your time and help
So Im going to go with a AN7510 from panasonic and a MAX5456 from maxim. and i have added a new diagrahm. can anyone tell me if it will or if it wont work. If it wont, can you advise me on what to fix.
o Not worried about the mute button, or the standbye, Balance or shutdown features
the cluster at the top of the circuit would be a 12-pin header for a connection containing the
audio left and right in, +5v, grd, speaker left +/- and right +/-, and tact switches leads for vol up +/-, and vol dn +/-
