3. (4.28, p.100) A 12 bit A/D converter has an input range of ±10V and is connected to an input amplifier with programmable gain of 1, 10, 100, or 500. The connected transducer has a maximum output of 7.5 mV. Select the appropriate gain to minimize the quantization error, and compute the quantization error as a percent of the maximum input voltage. 4. An inverting μA741C based amplifier like figure.3.13 is to have a gain of 10 and an input impedance of 10KQ. What will be the cutoff frequency and the values of R1 and R2. Assume the gain bandwidth product for a μA741C is 1 MHz.
