Low Distortion, Differential ADC Driver Data Sheet AD8138
www.analog.comThe differential output of the . AD8138 helps balance the input to differential ADCs, maximizing the performance of the ADC. The . AD8138. eliminates the need for a transformer with high performance ADCs, preserving the low frequency and dc infor-mation. The common-mode level of the differential output is adjustable by a voltage on the V OCM

A numeric relay generally contains many imple-mentations of these devices within its program-ming, and each instance of a device is referred to, herein, as an “element” in the relay. For example, while the Basler BE1-CDS220 is primarily a transformer differential relay (hence,

MT-019: DAC Interface Fundamentals - Analog Devices
www.analog.comThe transformer not only serves to convert the differential output into a single-ended signal, but it also isolates the output of the DAC from the reactive load presented by the LC filter, thereby improving overall distortion performance. An op amp connected as a differential to single-ended converter can be used to obtain a single-

Chapter 5
pages.mtu.eduBasic principles The transformer may be considered as a simple two-wheel 'gearbox' for electrical voltage and current. The primary winding is analogous to the input shaft The secondary winding is analogous to the output shaft. In this comparison, current is equivalent to shaft speed and voltage to shaft torque. In a gearbox, mechanical power (speed multiplied by torque) is …
