This application note discusses a design for a phantom antenna power-supply system compatible with the Digital Satellite Equipment Control (DiSEqC) communication standard, using the MAX16948 ...
48 V ‘phantom’ powering has become the standard for professional condenser microphones. The supply (or rather bias) voltage is applied over both wires of the balanced screened cable via two 6k8 ...
Professional condenser microphones require a 48-V supply to charge the internal capacitive transducer and power the internal buffer for the high-impedance transducer output. You can use a simple boost ...
