WebIt is also observed that the gain of the Op amp was determined by the external components for example resistors. We were able to work with amplifiers and prove the theoretical … Webanalogue voltage is to use an op-amp as a summing amplifier with a weighted resistor ``ladder'', as shown in Figure (36). Figure 36: A 4-bit DAC based upon summing the current through weighted resistors. At the start of the conversion process, a 4-bit input code, is applied to control the corresponding switches .Each switch
