The Inverting Operational Amplifier
The Open Loop Gain, ( Avo ) of an operational amplifier can be very high, as much as
1,000,000 (120dB) or more. However, this very high gain is of no real use to us as it
makes the

Weighted Summing Amplifier
R-2R Network Approach
Weighted Sum DAC
One way to achieve D/A conversion is to use a
summing amplifier.
This approach is not satisfactory for a large
number of bits because it
