    PGA output pin voltage not rising above 4V with change in input voltage

      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
