General Description
The ADC122S021 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 ADC122S021 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 one or two input signals at inputs IN1 and IN2.
The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many
common DSP serial interfaces.
The ADC122S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or
+5V supply is 2.2 mW and 7.9 mW, respectively. The power-down feature reduces the power consumption to just 0.14 µW using
a +3V supply, or 0.32 µW using a +5V supply.
The ADC122S021 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of −40°C to +85°C is
guaranteed.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
