DESCRIPTION
Using a successive approximation register (SAR) core, these ADCs provide a sample-and-hold front-end with no latency in conversions. The ADS8638 can measure up to eight inputs. In addition to the input multiplexer, the ADS8634/8 feature an internal temperature sensor, voltage reference, and a digital comparator for setting alarm thresholds on each input; therefore, a minimal amount of external components are required. A simple SPI-compatible interface provides for communication and control.
