The ADC124S021 is a low-power, four-channel
CMOS 12-bit analog-to-digital converter with a highspeed serial interface. Unlike the conventional
practice of specifying performance at a single sample
rate only, the ADC124S021 is fully specified over a
sample rate range of 50 ksps to 200 ksps. The
converter is based on a successive-approximation
register architecture with an internal track-and-hold
circuit. It can be configured to accept up to four input
signals at inputs IN1 through IN4.
The output serial data is straight binary, and is …
