ABSTRACT:
An output driver (100) for driving an external impedance load (160) comprising an output stage (110) and an impedance element (120). An input signal to the output stage (110) is controlled to provide an output signal that then drives the external impedance load (160).
The output stage (110) comprises an input controller (112) that couples to a current generator (114) and a current replicator (116). A voltage reference source (150) determines a quiescent output current level of the current generator (114). The impedance element (120) comprises a current modulating resistor (230) that couples a two polarity voltage supply (130) to the output stage (110).
Operations of the output driver (100) depends on the external load impedance (160). For a high external impedance load, the output driver (100) functions as a simple voltage follower. For a low external impedance load, the output driver (100) functions as a single-ended push-pull circuit and provides a low distortion output signal under low voltage supply conditions.
