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.
