ADS1015EVM, ADS1115EVM, ADS1015EVM-PDK, and
This user's guide describes the characteristics, operation, and use of the ADS1015EVM and
ADS1115EVM, both by themselves and as part of the ADS1015EVM-PDK or ADS1115EVM-PDK. These
evaluation modules (EVMs) are evaluation boards for the ADS1115, a 16-bit multi-channel, delta-sigma
analog-to-digital converter (ADC), and the ADS1015, a 12-bit version of the ADS1115. The EVM allows
evaluation of all aspects of the ADS1015 or ADS1115 device. Complete circuit descriptions, schematic
diagrams, and bills of material are included in this document.
