Are topping DACS any good?
Absolutely clean and transparent sound quality with plenty of detail. Bluetooth 5.0 input accepts AAC, aptX HD, and LDAC codecs. Some of the best-measured performance of any DAC I have reviewed. DAC can decode almost any bitrate and format.
How does R 2R ladder DAC work?
The R-2R resistor ladder network directly converts a parallel digital symbol/word into an analog voltage. Each digital input (b0, b1, etc.) adds its own weighted contribution to the analog output. This network has some unique and interesting properties.
What are the disadvantages of R-2R ladder DAC?
An alternative to the binary weighted input DAC is the R-2R Ladder, which uses fewer unique resistor values thus does not require precision resistors. A disadvantage of the former DAC design was its requirement of several different precise input resistor values: one unique value per binary input bit .
