interface.

Unlike

the

conventional

Variable Power Management

practice of specifying performance at a single sample

rate only, the ADC101S021 is fully specified over a

•

Single Power Supply with 2.7V - 5.25V Range

sample rate range of 50 ksps to 200 ksps. The

•

SPI™/QSPI™/MICROWIRE/DSP Compatible

converter is based upon a successive-approximation

register architecture with an internal track-and-hold

circuit.

•

Portable Systems

The output serial data is straight binary, and is

Remote Data Acquisition

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.
