ADS8634SRGET

12位， 1MSPS ，4 / 8通道，双极性输入， SAR模拟数字转换器 12-Bit, 1MSPS, 4-/8-Channel, Bipolar-Input, SAR Analog-to-Digital Converter

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.
