Hi,
I am going to use an ADS8556 EVM to get an analog input , pass it to DSP C6713 DSK through 5-6K Interface. The DSK will run a PID controller and pass the analog output through a DAC7741 EVM. My question is, what is the input impedance of the EVM? Will it be the input impedance of the THS4032 opamp and if so what is it.
On the output side the analog voltage from the DAC will drive the input for a piezo amplifier. The DAC7741EVM manual mentions an output buffer module. Would this module be suitable for diving external amplifier inputs as is in my case?
