DC1591A

Demonstration circuit 1591A features the LTC®6409 differential ADC driver. It incorporates a variety of passive components to support configurations for varied applications. On this board, two amplifier circuits are provided. One is single-ended, the other is a differential input and output. There is also a calibration circuit to de-embed the effects of other circuit components. The LTC6409 is a high-speed differential amplifier with superior distortion and low noise suitable for demanding communications transceivers, cellular base-stations, and other high-speed signal chain applications. These fully differential amplifiers accept single ended or differential inputs with almost no difference in distortion performance. Each part has the ability to adjust the output common-mode voltage without any additional components and flexible input common-mode ranges, which enable input signal DC coupling and level-shifting for ADC driving applications.
