This circuit will convert differential sources single ended unbalanced RCA signal. It is useful to connecting DAC with balanced outputs such as PCM1794, PCM1798, PCM1730 to an amplifier that only have RCA audio inputs. INA134 is used as a XLR differential digital receiver or buffer for RCA inputs.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
