DEMO MANUAL DC1493A 16-Bit Differential, ADC 2 with I C Interface DESCRIPTION Demonstration circuit 1493A features the LTC 2463, a to the target applications analog signals while using the 16-bit high performance analog-to-digital converter DC590 USB Serial Controller board and supplied software 2 (ADC) with an I C interface. The input is differential with a to measure performance. The exposed ground planes allow range of REF. The modulators proprietary sampling tech- proper grounding to prototype circuitry. After evaluating nique reduces the average input current to less than 50nA with Linear Technologys software, the digital signals can orders of magnitude lower than typical delta sigma be connected to the end applications processor/controller ADCs. for development of the serial interface. DC1493A is a member of Linear Technologys QuikEval Design les for this circuit board are available at family of demonstration boards. It is designed to allow easy DEMO MANUAL DC1493A QUICK START PROCEDURE Connect DC1493A to a DC590 USB Serial Controller using the supplied 14-conductor ribbon cable. Connect DC590 to host PC with a standard USB A/B cable. Run the evalu- ation software supplied with DC590 or downloaded from
