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 WSON and SOT-23 packages. Operation over the
industrial temperature range of −40°C to +85°C is ensured.
