The device includes a capacitor-based, successive-approximation register (SAR) ADC with inherent sample and hold. The device includes a 50-MHz, SPI-compatible serial interface. The interface is designed to support daisychaining or cascading of multiple devices. Furthermore, a Busy Indicator makes synchronizing with the digital host easy. The device unipolar, single-ended input range supports an input swing of...
