The first source of noise in this circuit is the internal DAC's resistive noise. An R-2R resistive ladder network provides a simple means of converting digital voltage signals into an equivalent analogue output.In this discussion, we consider the noise of the multiplying DAC (MDAC) in Figure 2. Open Circuit Circuit Description Circuit Graph *R-2R ladder* As its name implies, the 'ladder' description comes from the ladder-like configuration of the resistors used within the network.

The wave that comes from the DAC oscilates from 0 to 5V, the voltage follower is powered by 5V. Update: The pins are well conected and the signal is being well produced after the DAC, the problem seems to be the voltage follower.

If, as I understand, the DAC is an R/2R ladder then please show how this is connected to the processor.2, which has a similar three level reference selection to and. Ternary R2R DAC: One alternative to the traditional binary R2R structure for reduced power consumption in differential operation is the ternary R2R DAC shown in Fig.
