www.ti.com SNAS283D – MARCH 2005 – REVISED MARCH 2013 ADC124S101 4 Channel, 500 ksps to 1 Msps, 12-Bit A/D Converter
Check for Samples: ADC124S101 FEATURES DESCRIPTION The ADC124S101 is a low-power, four-channel
CMOS 12-bit analog-to-digital converter with a highspeed serial interface. Unlike the conventional
practice of specifying performance at a single sample
rate only, the ADC124S101 is fully specified over a
sample rate range of 500 ksps to 1 Msps. The
converter is based on a successive-approximation
register architecture with an internal track-and-hold
circuit. It can be configured to accept up to four input
signals at inputs IN1 through IN4. 1 2 Specified Over a Range of Sample Rates
Four 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: +0.9/-0.6 LSB (typ)
