The device operates with a 2.25-V to 5.5-V external reference. The device includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit. The device includes a 25-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 unipolar, single-ended input range for t...
