SBAS683B August 2014 – May 2020 ADS1120-Q1
PRODUCTION DATA.
The ADS1120-Q1 is a precision, 16-bit, ΔΣ ADC that offers many integrated features to ease the measurement of the most common sensor types including various types of temperature and bridge sensors. Primary considerations when designing an application with the ADS1120-Q1 include analog input filtering, establishing an appropriate external reference for ratiometric measurements, and setting the common-mode input voltage for the internal PGA. Connecting and configuring the serial interface appropriately is another concern. These considerations are discussed in the following sections.
