ADC122S101 2 Channel- 1 MSPS 12-Bit A/D Converter

The ADC122S101 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC122S101 is fully specified over a sample rate range of 500 kSPS to 1 MSPS. The conver.
