詳細(xì)描述

MAS6512 是一款電容傳感器信號(hào)調(diào)節(jié)器 IC，能夠連接單電容傳感器和差分電容傳感器。它使用 16 位電容數(shù)字轉(zhuǎn)換器，該轉(zhuǎn)換器采用 delta-sigma (ΔΣ) 轉(zhuǎn)換技術(shù)。輸出可以與電容差或電容比成正比。該 IC 專為滿足低功耗要求而設(shè)計(jì)，是電池供電系統(tǒng)的理想選擇。

除了電容測(cè)量外，該器件還有一個(gè)內(nèi)部溫度傳感器，用于溫度測(cè)量和溫度補(bǔ)償。256 位 EEPROM 存儲(chǔ)器在芯片上存儲(chǔ)微調(diào)和校準(zhǔn)系數(shù)。

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.
