An integrated circuit (100) may provide a high current, wide band, high fidelity output by providing a digital signal source (101) coupled to a first digital to analog source (102) and a second digital to analog source (103). The first digital to analog source (102) has a first power factor and a first fidelity factor, while the second digital to analog source (103) has a second power factor and a second fidelity factor, wherein the first power factor is greater than the second power factor. The outputs of the first and second digital to analog sources (107 and 108) are combined to provide a resultant (109), wherein the resultant (109) has a third power factor which is in the range of the first power factor and has a third fidelity factor which is greater than either the first fidelity factor the second fidelity factor.
