Figure 1 shows the LT6350 being used to convert a 0V to 5V single-ended input signal to differential for an ADC with differential inputs. In this case, the first amplifier is configured as a unity gain buffer and the single-ended input signal directly drives the high-impedance input of the amplifier. ADC Driver With Single-Ended Input to Differential Output. ADC Driver With Single-Ended Input to Differential Output. The LT6350 is a rail-to-rail input and output low noise single-ended to differential converter/ADC driver featuring fast settling time. It converts a high or low impedance, single-ended input signal to a low. ADI single-ended to differential amplifiers enable the processing of both single-ended inputs to complementary differential outputs or differential inputs to differential outputs. This provides a convenient solution when interfacing with analog-to-digital converters (ADCs). ADI also offers a series of differential receiver products. These provide great flexibility when interfacing signals to ADCs that have differential inputs. Instead of a single-ended output, the differential ADC driver produces a balanced differential output—with respect to VOCM—between VOP and VON. “P" indicates positive and “N" indicates negative.

Regardless of the topology, single-ended or differential, the system goal is to successfully deliver a desired signal to an analog-to-digital converter for digitization. The signal path consists of several RF blocks: the antenna, filters, low noise amplifier (LNA), mixer, ADC driver amplifier, and the ADC. The first. Single-ended and differential refer to the reference for a voltage. Single-ended is referred to ground while differential is referred to some other voltage. For a single-ended measurement, the LabJack converts the difference between the voltage. “The ISL70617SEH is the space industry's first true differential-ended ADC driver," said Philip Chesley, senior vice president of Precision Products at Intersil..
