ADUCM350BBCZ,Analogue Front End IC, 120-Pin BGA

The ADuCM350 device is a 16-bit precision, low-power meter-on-a-chip based on an ARM Cortex-M3 processor core. The ADuCM350 is designed with high-precision current, voltage and impedance measurement capabilities. It can be powered by a single coin-cell making it suitable for portable device applications. Suitable applications for the ADuCM350 include point-of-care medical diagnostics and wearable devices monitoring vital signs.
