Abstract
The present disclosure provides for improved DAC circuits and methods. In one embodiment, a digital-to-analog converter receives a digital signal and outputs a first analog output signal corresponding to the digital signal. A current buffer receives the first analog output signal and generates an analog output current. The current output digital-to-analog converter and the current buffer are constructed on an integrated circuit, and the analog output current is coupled to a pin of the integrated circuit. The pin of the integrated circuit receives the analog output current and provides the analog output current to additional circuitry external to the integrated circuit.
