ADUCM362BCPZ256

ADUCM362 is a fully integrated, 3.9KSPS, 24bit data acquisition system that incorporate dual, high performance, multichannel sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), a 32bit ARM Cortex™-M3 processor, and flash/EE memory on a single chip. It is designed for direct interfacing to external precision sensors in both wired and battery-powered applications. This device contains an on-chip 32KHz oscillator and an internal 16MHz high frequency oscillator. The high frequency oscillator is routed through a programmable clock divider from which the operating frequency of the processor core clock is generated. The maximum core clock speed is 16MHz; this speed is not limited by operating voltage or temperature. It is used in application such as industrial automation and process control, intelligent precision sensing systems, 4mA to 20mA loop-powered smart sensor systems, medical devices, patient monitoring etc.
