Analog DAC output voltage swing is not raising above 4V. I used voltage DAC and PGA with gain of 4. I set 1V from DAC output to PGA input I am getting 4V. When I increase the PGA input to 1.2V I am still getting 4V. Do I need to add a pull down resistor is 10k at the  analog output pin driven by PGA

I believe that PGA needs at least 0.6V headroom to operate. It will not produce 4.8V.
