DC1492A

DC1492A demonstration circuit features the LTC2462, a 16bit high performance ∆Σ analogue-to-digital converter (ADC) with an SPI interface. The input is bipolar with a range of ±REF/2. The modulator’s proprietary sampling technique reduces the average input current to less than 50nA – orders of magnitude lower than typical delta sigma ADCs. DC1492 is a member of QuickEval™ family of demonstration boards. It is designed to allow easy evaluation of the LTC2462 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.
