In signal theory the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system where noise is defined as any signal other than the one being monitored.

Dac noise floor. In radio communication and electronics this may include thermal noise black body cosmic noise as well as atmospheric noise from distant thunderstorms and. The most common real reason to need a dac outside of a high noise floor is because of clocks being out of sync. Snr process gain and fft noise floor relationships. 24 bit lsb noise floor voltage 0 3uv.

18 bit lsb noise floor voltage 19uv. Rms noise voltage or power is specified along with a bandwidth. 16 bit lsb noise floor voltage 76uv. I would feed my dac a 24 96 album then pause the song and crank up my amp volume to see where the noise floor was at.

The first item tells me this dac is likely not using any dither or noise floor modulation scheme which would certainly help contribute to the extraordinarily quiet signal to noise ratio mola mola specifies on their page. 20 bit lsb noise floor voltage 4 75uv. Figure 6 shows the fft output for an ideal 12 bit adc. It is preferable to use a fft and compare noise floors this is the best if you know what the fft noise floor actually is and how it is computed.

It was at least twice as loud when i did this with a 24 96 track versus a 16 44 or 24 48. Then you can compute the rms power digitally and compare. Apart from quantization noise that defines the theoretical noise minimum for an ideal dac nonlinearity is the major contribution. The rf dac s ability to synthesize multiple bands improves the overall performance of the system in addition to reducing complexity and therefore size and cost.

Note that the average value of the noise floor of the fft is approximately 107 db below full scale but the theoretical snr of a 12 bit adc. To my opinion spurious free dynamic range sfdr would be a common measure to describe the noise floor. In your source your cd blu ray player portable device etc there is what s known as a digital clock this tells your dac in the same device or in another like a receiver the timing of the content. When i was testing last night the noise floor i m talking about isn t in the recording it s in the dac itself.

Based on a 2 5v output on a dac higher than average below are the voltages power supply noise must be below in order to hear the lsb. The second reason for better noise floor is reduction of the insertion loss for the antenna when transmitting in multiple bands since no combiner is needed. Turn dac off then acquire to measure soundcard noise floor. The exact same precautions apply to measuring dac distortion with an analog spectrum analyzer.
