MAS6512 电容式传感器信号接口IC

详细描述

MAS6512 是一款电容传感器信号调节器 IC，能够连接单电容传感器和差分电容传感器。它使用 16 位电容数字转换器，该转换器采用 delta-sigma (ΔΣ) 转换技术。输出可以与电容差或电容比成正比。该 IC 专为满足低功耗要求而设计，是电池供电系统的理想选择。

除了电容测量外，该器件还有一个内部温度传感器，用于温度测量和温度补偿。256 位 EEPROM 存储器在芯片上存储微调和校准系数。

MAS6512 is a capacitive sensor signal conditioner IC, capable to interface both single and differential capacitance sensors. It uses a 16-bit Capacitance-to-Digital Converter, which employs a delta-sigma (ΔΣ) conversion technique. The output can be proportional either to capacitance difference or to capacitance ratio. The IC is designed especially to meet the requirement for low power consumption, thus making it an ideal choice for battery powered systems.

In addition to capacitance measurement the device has an internal temperature sensor for temperature measurement and temperature compensation purposes. The 256-bit EEPROM memory stores trimming and calibration coefficients on chip.
