DC1718A

DC1718A demonstration circuit features the LTC®2471, a 16-bit high-performance sigma delta ADC with an I2C interface. The input is unipolar with a range of 0-REF. The modulator’s proprietary sampling technique reduces the average input current to less than 50nA – orders of magnitude lower than typical delta-sigma ADCs. DC1718 is a member of QuikEval™ family of demonstration boards. It is designed to allow easy evaluation of the LTC2471 and may be connected directly to the target application’s analogue signals while using the DC590 USB serial controller board and supplied software to measure performance. The exposed ground planes allow proper grounding to prototype circuitry. After evaluating software, the digital signals can be connected to the end application’s processor/controller for development of the serial interface.
