com February 25, 2008 ADC122S655 Dual 12-Bit, 200 kSPS to 500 kSPS, Simultaneous Sampling A/D Converter General Description The ADC122S655 is a dual 12-bit, 200 kSPS to 500 kSPS 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 common-mode signal rejection.
The ADC122S655 features an external reference that can be varied from 1.
0V to VA.
The ADC122S655's serial data output is binary 2's complement and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE™, and many common DSP serial interfaces.
The serial clock (SCLK)...
