ADUC845:  Precision Analog Microcontroller: 12MIPS 8052 Flash MCU + 10-Ch 24-Bit ADC + 12-Bit DAC

Product Description

The ADuC845 MicroConverter is a fully integrated Dual 24-bit, Multi-Channel Sigma Delta ADC and Flash microcontroller on a single chip. This device is a multi-channel extension of ADI’s popular ADuC844 and ADuC846 MicroConverter family and is optimized for applications in industrial control, smart sensors, loadcells and instrumentation that require precison acquisition of multiple (up to 10) channels.

The ADuC845 is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3 V or 5 V power supply over the standard industrial temperature range. Like all of ADI's MicroConverter products, the device is supported by the QuickStart and QuickStart-Plus development systems.
