hi
i am using ADc0804 & 0808 in my application ,while testing ADc0804...i applied 5 volts on V+,V- i got stable o/p on two pins but pulses on other o/ps....what can be th ereason???? I believe this thread is in continuation to your answering machine project. In one of other threads, you said that you are restricted to use 8051 only. Is there any restriction on the use of ADC0804 and DAC08 as well? If not what is wrong with ISD chips? you don't need RAM, you don't need ADC, you don't need DAC and you can interface it to 8051 as well. Regarding current question, you should provide more details like the schematic of your test circuit, what values are you getting at the output against some known inputs, what is clock frequency of ADC0804 etc. Only then someone can answer your question. |
