A digital-to-analog converter (DAC) circuit includes a first DAC that produces a first analog output signal based upon a received multi-bit digital signal and upon a received clock. A second DAC that produces a second analog output signal based upon the received multi-bit digital signal and upon the received clock, wherein the first and second DACs are connected in parallel and process the same multi-bit digital signal. In one embodiment, the DACs produce differential signals. A low pass filter connected to receive the first and second analog outputs is configured to sum the first and second analog outputs and to filter the summed first and second analog outputs to produce an ingoing analog signal. An amplifier is connected to receive the ingoing analog signal to produce an amplified ingoing analog signal.
