Question

In a 4 bit weighted register D/A converter, the register value corresponding to LSB is $32K\Omega$ the register value corresponding to MSB will be _________________.

• A. $32\Omega$
• B. $16\Omega$
• C. $8\Omega$
• D. $4\Omega$

Answer 1

The correct option is D $4\Omega$

In a 4 bit weighted register D/A converter, the register value corresponding to LSB is 32KΩ the register value corresponding to MSB will be 4Ω.

In the weighted resistor type DAC, each digital level is converted into an equivalent analog voltage or current.

DAC converter produces an output current of voltage proportional to digital quantity to its output. In the circuit op-amp is used as current to voltage converter.

Signals can easily be stored and transmitted in digital form; a DAC is used for the signal to be recognized by human senses or non-digital systems.
