April 2005 .. ADC122S051 2 Channel, 500 kSPS 12-Bit A/D Converter ADC122S051 2 Channel, 500 kSPS 12-Bit A/D Converter General Description 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 converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals at inputs IN1 and IN2. The output serial data is straight binary, and is...
