Other Parts Discussed in Thread: ADC3244
Support Path: /Reference designs/Help finding technical applications collateral/
All the examples for the ADC32J45 (and the EVM) show transformer coupling to INA and INB. We are planning to use this as an ADC for a zero-IF receiver, so we need the input frequency range to extend to DC. Is this possible with this part? If so, is there an example circuit of how to do this, using Vref? Is there a recommended differential driver chip? We are sampling at 160 MHz, the signal bandwidth is 0-50 MHz approximately.
