HI all,
I am doing a DDS function generator by using ARDUINO microcontroller and AD 9850 chip module,the output waveform according to data sheet of DDS chip module is 1 V which is too low,therefore I need to design an amplifier for it which can generate output sinewave within 1-20 V.And the problem I am facing right now is when frequency up to MHZ,the output from DDS chip module begin to decrease,when frequency is 38.5 MHz, the output amplitude equal to 250mV.
I am planning to use LM741 opamp to implement it, so do it possible to implement by using LM 741 ?or have any suggestion?
THanks
