ADC122S051 2 Channel- 500 kSPS 12-Bit A/D Converter

The ADC122S051 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 ADC122S051 is fully specified over a sample rate range of 200 kSPS to 500 kSPS. The conv.
