詳細(xì)描述

MAS6505是專為壓阻式傳感器模塊設(shè)計的高分辨率傳感器信號接口IC。模擬前端 (AFE) 包括一個斬波放大器，其輸入噪聲低至 0.27uVrms。22 位模數(shù)轉(zhuǎn)換器 (ADC) 采用具有高分辨率性能的 delta-sigma 轉(zhuǎn)換技術(shù)。它可以在非常寬的電源電壓范圍 (1.71V…5.5V) 下運(yùn)行，并且具有極低的電流消耗（低至 0.8uA，每秒測量一次），使其成為電池供電應(yīng)用的理想解決方案。支持來自傳感器電橋電阻或外部二極管的溫度感測。512 位 EEPROM 存儲器可用于在芯片上存儲傳感器微調(diào)和校準(zhǔn)系數(shù)。該器件使用標(biāo)準(zhǔn) I2C 和 SPI 串行總線接口進(jìn)行操作。

MAS6505 is a high resolution sensor signal interface IC designed for piezoresistive sensor modules. Analog Front-End (AFE) comprises of a chopper amplifier having input noise down to 0.27uVrms. The 22-bit Analog-to-Digital Converter (ADC) employs delta-sigma conversion technique with high resolution performance. It can operate from a very wide range of supply voltages (1.71V…5.5V) and it has extremely low current consumption (down to 0.8uA, one measurement in a second) which make it an ideal solution for battery powered applications. Temperature sensing either from sensor bridge resistance or external diode are both supported. 512-bit EEPROM memory is available for storing sensor trimming and calibration coefficients on chip. The device is operated using standard I2C and SPI serial bus interfaces.
