Piezoresistive Sensor Signal Interface IC

 

 

MAS6502 is a 16 bit Analog-to-Digital Converter (ADC) designed for piezoresistive sensor modules. It's designed especially to meet the requirement for low power consumption, thus making it an ideal choice for battery powered systems.  Current consumption values of 2.3 µA (one pressure conversion in a second) or less can be achieved. The 256-bit EEPROM memory stores trimming and calibration coefficients on chip.

In addition to pressure measurement the device can be configured for temperature measurement using the external sensor bridge and the built-in sensor sampling switches. An advantage with this is that the temperature is measured directly on the bridge and not on the IC which means the IC doesn’t need to be placed directly beside the sensor bridge.
