FEATURES
DESCRIPTION
The
ADC102S021
is
a
low-power,
two-channel
2
Specified Over a Range of Sample Rates.
CMOS 10-bit analog-to-digital converter with a high-
Two Input Channels
speed
serial
interface.
Unlike
the
conventional
Variable Power Management
practice of specifying performance at a single sample
rate only, the ADC102S021 is fully specified over a
Single Power Supply with 2.7V - 5.25V Range
sample rate range of 50 ksps to 200 ksps. The
converter is based on a successive-approximation
APPLICATIONS
register architecture with an internal track-and-hold
Portable Systems
circuit. It can be configured to accept one or two input
signals at inputs IN1 and IN2.
Remote Data Acquisition
Instrumentation and Control Systems
The output serial data is straight binary, and is
compatible with several standards, such as SPI™,
QSPI™, MICROWIRE, and many common DSP
KEY SPECIFICATIONS
serial interfaces.
DNL: ± 0.13 LSB (typ)
The ADC102S021 operates with a single supply that
INL: ± 0.13 LSB (typ)
can range from +2.7V to +5.25V. Normal power
SNR: 61.8 dB (typ)
consumption using a +3V or +5V supply is 1.94 mW
Power Consumption
and 6.9 mW, respectively. The power-down feature
reduces the power consumption to just 0.12 µW using
3V Supply: 1.94mW (typ)
a +3V supply, or 0.47 µW using a +5V supply.
5V Supply: 6.9 mW (typ)
The ADC102S021 is packaged in an 8-lead VSSOP
package. Operation is specified over the industrial
temperature range of
−40°C to +85°C.
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.
