| description: | |
| The ADS7128 and ADS7138 chips are 12-bit, 8 channel analog-to-digital |
| converters (ADC) with build-in digital window comparator (DWC), using the |
| I2C interface. |
| ADS7128 differs in the addition of further hardware features, like a |
| root-mean-square (RMS) and a zero-crossing-detect (ZCD) module. |
