ADUC834:  Precision Analog Microcontroller: 1MIPS 8052 MCU + 62kB Flash + 16/24-Bit ADC + 12-Bit DAC

Product Details


The ADuC834 MicroConverter® is a fully integrated 24-bit data acquisition system-on-a-chip. Like all of ADI's MicroConverter products, it features precision A/D & D/A conversion and a Flash microcontroller on a single chip.

The ADuC834 is 100% backward compatible (hardware and software) with the ADuC824. It is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply.
