DESCRIPTION
The ADC101S101 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 ADC101S101 is fully specified over a
sample rate range of 500 ksps to 1 Msps. 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 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.
