Answer 1

4-bit D/A converters.....

Answer 2

The practical use of binary-weighted digital-to-analog converters is limited to 4-bit D/A converters.

• The paired weighted DAC, which contains individual electrical components for each piece of the DAC connected to a summing point.
• These exact voltages or flows sum to the right result esteem.
• This is one of the quickest conversion techniques yet experiences unfortunate exactness in light of the great accuracy expected for every individual voltage or current.
• Such high-accuracy components are costly, so this kind of converter is typically restricted to an 8-digit goal or less.
• As you increment the number of pieces the resistor esteems likewise get multiplied.
• At higher reach, you can't find exact resistor values which would amount to critical blunder because of the resilience of resistors.
• Consequently, it isn't recommended to utilize the R-2R organization past 4 pieces.
