DESCRIPTION
The ADC101S051 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 ADC101S051 is fully specified over a
sample rate range of 200 ksps to 500 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 ADC101S051 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 2.7
mW and 9.7 mW, respectively. The power-down
feature reduces the power consumption to as low as
2.6 µW using a +5.25V supply.
The ADC101S051 is packaged in 6-lead WSON and
SOT-23 packages. Operation is specified over the
temperature range of −40°C to +85°C for the
ADC101S051 and −40°C to +125°C for the
ADC101S051Q.
