DESCRIPTION
The ADC122S021 is a low-power, two-channel
CMOS 12-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 ADC122S021 is fully specified over a
sample rate range of 50 ksps to 200 ksps. The
converter is based on a successive-approximation
register architecture with an internal track-and-hold
circuit. It can be configured to accept one or two input
signals at inputs IN1 and IN2.
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 ADC122S021 operates with a single supply that
can range from +2.7V to +5.25V. Normal power
consumption using a +3V or +5V supply is 2.2 mW
and 7.9 mW, respectively. The power-down feature
reduces the power consumption to just 0.14 μW using
a +3V supply, or 0.32 μW using a +5V supply.
The ADC122S021 is packaged in an 8-lead VSSSOP
package. Operation over the industrial temperature
range of −40°C to +85°C is ensured.
