DC1629A

DC1629A demonstration circuit features the LTC2472, a 16-bit high performance Δ∑ analogue-to-digital converter (ADC) with an SPI interface. The input is differential with a range of ±VREF The modulator’s proprietary sampling technique reduces the average input current to less than 50nA – orders of magnitude lower than typical delta sigma ADCs. DC1629A is a member of QuikEval™ family of demonstration boards. It is designed to allow easy evaluation of the LTC2472 and may be connected directly to the target application’s analogue signals while using the INPUTS 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.

• Selectable 208sps/833sps, 16-Bit ΔΣ ADC with 10ppm/°C max precision reference
