Webtype DACs, sometimes called current-steering or ladder DACs. The architecture for the R-2R DAC is very similar to instrumentation-grade DACs, where all bits are converted simultaneously (although these DACs accept standard serial digital audio data, they utilize internal serial-to-parallel converters). This architecture is used in Burr-Brown ... Web27 de jun. de 2024 · Some listeners have called DS DACs cold and sterile compared to their R-2R counterparts while I personally find DS DACs to be a tiny bit less interesting, just a shade on the boring side. IIRC, DS DACs make a lot of guesses and approximations when decoding a digital signal, then use a series of filters after the fact to clean up the mess.

WebA basic R–2R resistor ladder network is shown in Figure 1. Bit a n−1 (most significant bit, MSB) through bit a 0 (least significant bit, LSB) are driven from digital logic gates. Ideally, the bit inputs are switched between V = 0 (logic 0) and V = V ref (logic 1). The R–2R network causes these digital bits to be weighted in their contribution to the output voltage V out.
