5.6.3 General Purpose Application Examples

The SNSR-DUAL-ADC-EVM can be used for general evaluation of both ADS122S14 precision ADCs and is not restricted for sensor measurement applications. Each ADC can measure two differential inputs, four single-ended inputs, or a combination of both input types. Verify all input signals meet the requirements in Table 4-1.
