ADS8638SRGER

The ADS8638SRGER is a 12-bit Analog-to-digital Converter (ADC) capable of measuring inputs up to ±10V at 1MSPS. Using a successive approximation register (SAR) core, this ADC provides a sample-and-hold front-end with No Latency in conversions. The ADC includes an input multiplexer (mux) for measuring up to four inputs. In addition to the input multiplexer, the ADC features 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. The digital supply operates from 5V all the way down to 1.8V for direct connection to a wide range of processors and controllers.
