illustrate

The ADC122S021 is a low power, dual high speed serial interface CMOS 12-bit analog-to-digital converter. Unlike conventional practice of specifying performance at a single sample rate, the ADC122S021 fully specifies a sample rate range of 50 ksps in the range of 200 ksps. The converter is based on a successive approximation register architecture with internal sample-and-hold circuitry. It can be configured to accept one or two inputs in the input signals IN1 and IN2.

THE SERIAL DATA OUTPUT IS DIRECTLY BINARY AND COMPATIBLE WITH SERIAL INTERFACES OF SEVERAL STANDARDS SUCH AS SPI™, QSPI ™, MICROWIRE, AND MANY GENERAL-PURPOSE DSPS.

The ADC122S021 operates with a single supply and can range from +2.7 V to +5.25 five Normal power consumption using +3 V or +5 V supplies is 2.2 MW and 7.9 mW, respectively. The power-down function reduces power consumption by only 0.14 microwatts from a +3 V supply, or 0.32 microwatts from a +5 V supply.

The ADC122S021 is packaged in an 8-lead MSOP package. Operating at -40°C with an industrial temperature range of 85°C is guaranteed.
