Features
| | Specified over a range of sample rates. |

Description The ADC101S021 is a low-power, single channel CMOS 10-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 ADC101S021 is fully specified
over a sample rate range of 50 ksps to 200 ksps. The converter is based upon a successive-approximation register architecture
with an internal track-and-hold circuit.
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 ADC101S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3.6V
or +5.25V supply is 2.34 mW and 8.9 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6
µW using a +5.25V supply.
The ADC101S021 is packaged in 6-lead LLP and SOT-23 packages. 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.
