    Some ADC questions...

    how to get the sampling rate of the ADC from datasheet??? What is SPS??is it same as sampling rate? what is throughput???

    What is function of CA3130 and 40106 schmitt trigger here ?

    HELP HELP!!!!! anyone know what is function of CA3130 and 40106 schmitt trigger(NOT gate) in the circuit?? if CA3130 is comparatot, then how it compare the digital ouput from ADC with the reference voltage??? can state the condition??? thank you

    doubt with the component function~

    since the digital output is from ADC, so u means the CA3130 comparator is used to compare the digital signal with the reference voltage??? can state down the condition to compare???

    Questions about NAND gate at WR in this ADC

    Re: some question to ask so in the design i attached, what is the function of the NAND gate to control the ADc?? Another design is attached, what is the function and operation of the CA3130 and 40106???

    Questions about NAND gate at WR in this ADC

    some question to ask "the nand gate with resistor and capacitor form an oscillator" means the 4093 NAND gate is used as oscillator????

    Questions about NAND gate at WR in this ADC

    some question to ask from the file i attached, anyone know about how does this ADC work?? and what is the use of the NAND gate at WR??? then what is the voltage that used at pin 9 (is it 6V) if VSS is 12V??? thank you~~

    doubt with the component function~

    from the figure that i posted, anyone know what is function of CA3130 and 40106 schmitt trigger(NOT gate) in the circuit????/ thank you~~

    Digital Audio Amplifier~~need help!!

    Does anyone know about digital amplfier??? If do, i need for the schematics circuits and design circuits.....Is it need to use microcontroller in circuits? thank you~~~
