i will run it to 3 meters, i need flat up to 16khz, im gonna use pots low to high levelCombined with a (long)cable capacitance you will recognice an attenuation of high frequencies.
i thought opamp was best at unity, by the way i gonna change my feedback to 20kNE5534 are stable with a gian >=3. They are not stable at unity gain, or gain of 2
i dont understand, but my pwero supply is bipolar -/+9 volts 500mA regulated by 337 and 317the high input bias current of the NE5534 will produce a noticeable output DC voltage (first stage, 100k input, gain of 2, 500nA --> 100mV !!!
can he drive heaphone? im just want volume in headphone even its is not linear or goodi´d perfer a single OPAMP(or dedicated headphone Amp) instead of paralleling two OPAMPs.
living in the 3rd world country is adding the problemIt looks like the NE5534 is too old for your circuit
Yes, but especially this is a bad solution is you use standard electrolytics instead of high quality audio components.can back to back electronlytic sub to bipolar?
:?: Yes, a dedicated headphone amp can drive headphones. ;-) , or you use an OPAMP with high current drive ability.can he drive heaphone? im just want volume in headphone even its is not linear or good
The bias current of the OPAMP and the resulting DC at the output has nothing to do with your power supply.i dont understand, but my pwero supply is bipolar -/+9 volts 500mA regulated by 337 and 317
