hey, i need your help for making a differential amplifier using op-amp LM741.
I'm currently working on my finals creating an OQPSK modulator using IC AD8345. in the datasheet it is said that the input should be differential amplified and dc biased by 0.7 volt for 1.2Vpp (the maximum input for the modulator).
my bit stream for the input is currently 5-6vpp with 600KHz frequencies , and i need to convert it as i mentioned above. (in the datasheet, it is mentioned that diff. amplifier such as AD8132 can be used but it's hard to find in my country. nb: i bought the modulator from china and forget to buy the diff. amplifier).
pls help me, your answer is really appreciated.
