ADC122S625
Description The ADC122S625 is a dual 12-bit, 50 k SPS to 200 k SPS simultaneous sampling Analog-to-Digital (A/D) converter. The analog inputs on both channels are sampled simultaneously to preserve their relative phase information to each other. The converter is based on a successive-approximation register architecture where the differential nature of the analog inputs is maintained from the internal track-and-hold circuits throughout the A/D converter to provide excellent monmode signal rejection. The ADC122S625 features an external reference that can be varied from 1.0V to VA. The ADC122S625's serial data output is binary 2's plement and is patible with several standards, such as SPI™, QSPI™, MICROWIRE™, and many mon DSP serial interfaces. The serial clock (SCLK) and chip select bar (CS) are shared by both channels. Operating from a single 5V analog supply and a reference voltage of 2.5V, the total power consumption while operating at 200 k SPS is typically 8.6 m W. With the ADC122S625...
