The subsequent voltage-source multiplying DAC is to be utilized to convert the digital data stream "11" and "01" to an analog signal. It has 2-bit inputs and hence is capable of converting two bits of digital data into analog voltage in a single cycle. Determine the expected voltage levels at the output? (Digital control operates such that logical "1" makes a connection to Vcc and logical 0 makes a connection to ground.)
A) - Vcc and - (3/2) Vcc
B) - (3/2) Vcc and -Vcc
C) - (1.5) Vcc and - (0.5) Vcc
D) - Vcc and - (0.5) Vcc
