DESCRIPTION
The ADC081S101 is a low-power, single channel
CMOS 8-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 ADC081S101 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 ADC081S101 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 10.0 mW, respectively. The power-down feature
reduces the power consumption to just 2.5 µW using
a +5V supply.
The ADC081S101 is packaged in an 6-lead WSON
and SOT-23 packages. Operation over the industrial
temperature range of −40°C to +85°C is ensured.
