ADC122S101 2 Channel, 1 MSPS 12-Bit A/D Converter
General Description
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 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 compatible w...
