Driving Differential ADCs.pdfdesignfeature By Sally Paterson, Analog Devices Inc CONVERTING A SINGLE-ENDED SIGNAL TO A DIFFERENTIAL SIGNAL BEFORE THE ANALOG-TO-DIGITAL CONVERSION CAN IMPROVE THE PERFORMANCE OF YOUR DATA-ACQUISITION SYSTEM. Maximize performance when driving differential ADCs sing differential signals in data-acquisition signals. It also provides common-mode level shift- U systems is becoming increasingly popular be- cause differential signals are highly immune to system noise based on the common-mode rejection ing and buffering of the analog input signal. In Figure 1, a bipolar, single-ended signal with an ……
