    Hi everyone

    I was hoping some one may be able to advise me on an ic i am proposing to code for. I only have one and would not like to make any errors before i plug it up.
    the ic is the maxim 261 http://www.maximintegrated.com/en/products/analog/analog-filters/MAX261.html

    I would like to drive logic high 5v logic low 0v
    on pins 6 ,7 ,10, 14, 15, 19

    and the same for the clock on pin 11 ,12

    am i correct in assuming this is ok with a +5v -5v power supply

    thank you for reading

    cheers

    thanks

    Yes i have read through the datasheet

    I just wanted confirmation as the sheet has many versions using + and minus voltages...

    thank you

    Hello,

    Basicaly the + Volts and - 5 Volts are needed for the analog part of the chip.
    There is however an example for single supply voltage in fig 16 on page 21.

    hi
    thanks again for the reply

    sorry maybe i am being confusing

    I understand the +5 -5 power supply but just wanted to confirm
    i send high and lows to logic pins at 5v high 0v low
    thanks again
