PGA | Cypress Semiconductor
I went into sample project of Programmable Gain Amplifier(PGA) in PSoC creator, when i give input as
Freq:500 hz,,input voltage=.2v,,Gain =1,,Medium power,Offset=0,,Vref=internal vss the output obtained is not exact as input as i shown in Pic..
But when i Increase the Offset to 1v its giving the correct output .
Later i increased the gain to "2" and for every offset value(0,1,2,3) the output voltage i am getting is equal to the input voltage.....plz help me in getting the correct output....
