Unlike

the

practice of specifying performance at a single sample

rate only, the ADC101S101 is fully specified over a

Single Power Supply with 2.7V - 5.25V Range

sample rate range of 500 ksps to 1 Msps. 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

compatible with several standards, such as SPI™,

QSPI™, MICROWIRE, and many common DSP

serial interfaces.

The ADC101S101 operates with a single supply that

can range from +2.7V to +5.25V. Normal power

consumption using a +3V or +5V supply is 2.0 mW

and 10 mW, respectively. The power-down feature

reduces the power consumption to as low as 2.5 µW

using a +5V supply.

The ADC101S101 is packaged in 6-lead WSON and

SOT-23 packages. Operation over the industrial

temperature range of

−40°C to +85°C is ensured.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
