www.ti.com SNAS257E – NOVEMBER 2004 – REVISED MARCH 2013 ADC122S051/ADC122S051Q 2 Channel, 200 ksps to 500 ksps 12-Bit A/D Converter
Check for Samples: ADC122S051 FEATURES DESCRIPTION APPLICATIONS The ADC122S051/ADC122S051Q 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
ADC122S051/ADC122S051Q is fully specified over a
sample rate range of 200 ksps to 500 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 SPIв„ў,
QSPIв„ў, MICROWIRE, and many common DSP
serial interfaces. 1 2 Specified Over a Range of Sample Rates.
