ADC122S655 Dual 12-Bit - 200 kSPS to 500 kSPS - Simultaneous Sampling A/D Converter

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 archi.

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) and chip select bar (CS) are shared by both
