Audio differential bus receiver for audio/video interconnection |
摘要 |
Audio bus receiver includes a pair of bipolar transistors each having a base coupled via a respective resistor to a respective bus receiver input terminal, each having an emitter that is diode coupled to a respective current source and each having a collector coupled via a respective load resistor to a source of reference potential. The emitters are coupled together via a gain control resistor and the collectors are coupled to an output terminal via a differential amplifier. Advantageously, the receiver avoids loading the bus under power-down conditions without requiring the use of stand-by power supplies. Additionally, high common mode rejection is achieved without need for precision matching of components and only a single supply voltage is required for operation.
