ADuC841 - Analog Devices

ADuC841 MicroConverter 12-Bit ADCs/DACs

The ADuC841/ADuC842/ADuC8431 are complete smart transducer front ends, that integrates a high performance selfcalibrating multichannel ADC, a dual DAC, and an optimized single-cycle 20 MHz 8-bit MCU (8051 instruction set compatible) on a single chip. The ADuC841 and ADuC842 are identical with the exception of the clock oscillator circuit; the ADuC841 is cl.
