Description
General part information
ADS8638 Series
The ADS8634 and ADS8638 (ADS8634/8) are 12-bit analog-to-digital converters (ADCs) capable of measuring inputs up to ±10V at 1MSPS. Using a successive approximation register (SAR) core, these ADCs provide a sample-and-hold front-end with no latency in conversions. The ADS8634 includes an input multiplexer (mux) for measuring up to four inputs. 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. The digital supply operates from 5V all the way down to 1.8V for direct connection to a wide range of processors and controllers.
Ideal for demanding industrial measurement applications, the ADS8634/8 are fully specified over the extended industrial temperature range of –40°C to +125°C and are available in a small form-factor QFN-24 package.
