Micro Analog Systems Oy
October 18, 2013
Micro Analog Systems OY, Helsinki, Finland, offers the MAS6503 piezoresistive sensor signal interface IC for pressure sensors. It has very low power consumption, 1.8 V operation, VDD level monitoring, and a ratiometric 24 bit analog-to-digital converter (ADC that uses a delta-sigma (∆Σ) conversion technique and SPI or I2C bus with programmable I2C address and EEPROM calibration memory. The resolution for a signal range of 373 mV is 17.4 bits. Overall current consumption values of 18.3 μA (one conversion in a second at maximum resolution) or less can be achieved. Applications include calibrated piezoresistive pressure modules, temperature measurement, battery-powered systems, low-frequency measurement applications, current/power consumption critical systems, navigation systems, and industrial process control applications in noisy environments.
