www.ti.com SNAS281G – FEBRUARY 2005 – REVISED MARCH 2013 ADC102S021 2 Channel, 50 ksps to 200 ksps, 10-Bit A/D Converter
Check for Samples: ADC102S021 FEATURES DESCRIPTION The ADC102S021 is a low-power, two-channel
CMOS 10-bit analog-to-digital converter with a highspeed serial interface. Unlike the conventional
practice of specifying performance at a single sample
rate only, the ADC102S021 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. 1 2 Specified Over a Range of Sample Rates.
Two Input Channels
Variable Power Management
Single Power Supply with 2.7V -5.25V Range APPLICATIONS Portable Systems
Remote Data Acquisition
Instrumentation and Control Systems The output serial data is straight binary, and is
compatible with several standards, such as SPIв„ў,
QSPIв„ў, MICROWIRE, and many common DSP
serial interfaces. KEY SPECIFICATIONS DNL: В± 0.13 LSB (typ)
