OZ9350数据手册O2Micro中文资料规格书

描述 Description

OZ9350 is an AFE IC for 4-7 cell battery pack applications. It is designed to work with a host microcontroller and it’s Analog-to-Digital Converter (ADC).\r
\r
OZ9350’s internal analog multiplexer level shifts and conditions the individual cell voltages becoming a ground referenced signal, that a microcontroller can directly measure, increasing accuracy, eliminating discrete components and simplifying analog design.
