4.2 Single-Ended Approach

If the processor/FPGA have only a single-channel input into the ADC, a single-ended operational amplifier such as the TLV365 can be used instead of a fully differential amplifier and the same implementation can be followed with an external single-ended ADC such as ADS7042.
