Demonstration circuit 800 features the LT1993-X Differential Amplifier and ADC Driver. It incorporates a variety of passive components to support configurations for varied applications. Single-ended or differential input and output configurations are possible, and there is a calibration circuit to null out the effects of other circuit components. DC800A-A contains the LT1993-2, DC800A-B contains the LT1993-4, and DC800A-C contains the LT1993-10. The LTC1993-X is a high-speed differential amplifier with superior distortion and noise performance, perfect for demanding communications transceiver applications and other high-speed mixed signal applications. The LTC1993- X accepts single-ended or differential inputs with almost no difference in distortion performance. One standout feature of the LTC1993-X is the ability to independently adjust the output common-mode voltage, which allows output level shifting without any additional components. See the LT1993-X datasheet for information on typical performance specifications to expect when using the DC800.
