The ADuC847/ADuC848 MicroConverter products are fully integrated 24-Bit/16-Bit, Multi-Channel Sigma-Delta ADC and Flash Microcontroller on a single chip. These devices are optimized for applications in industrial control, smart sensors, loadcells and instrumentation that require precision acquisition of multiple (up to 10) channels.
The ADuC847/ADuC848 are available is 52-pin PQFP or 56-pin CSP packages and operates on a 3 V or 5 V power supply and are specified up to 125ºC (CSP up to 85ºC only). Like all of ADI’s MicroConverter products, the device is supported by the QuickStart and QuickStart-Plus range of development tools.
