Other Parts Discussed in Thread: DAC3283EVM, , THS4509, DAC3283
Hi,
I want to make loopback environment of DAC3283EVM & ADS4149EVM for test.
So, I will revise DAC3283EVM and ADS4149EVM.
R1 & R3 resistive network will use 25-ohm resistor not 100-ohm. Then DAC output is directly connected to ADC input through SMA cable.
ADC EVM is revised so that ADC analog input specification is met. (Vcm = 1V , differential swing = 2Vpp)
Does this circuit revision make sense?
Is R8-R9-C1 for termination around Vcm necessary? or Is it possible with AMP(THS4509) only?
I'll wait for your response.
Best regards.
