High Resolution Low Power Piezo Resistive Sensor Signal Interface IC
Micro Analog Systems Oy today has MAS6503, a 24-bit Piezo Resistive Sensor Signal Interface IC primarily intended for MEMS based pressure sensor modules.
The device uses a ratiometric AD-converter principle employing a delta-sigma (DS) conversion technique, giving very good noise performance. Its current consumption is extremely low (18.3 μA, one pressure conversion in a second at maximum resolution and including sensor bridge current) and it can operate at low supply voltage from 1.8 V to 3.6 V which makes it an ideal solution for interfacing a piezoresistive sensor in power consumption critical portable applications. The effective number of bits (ENOB) of the ADC is 17.4 bits.
The over sampling ratio (OSR) of the
DS-converter has five values to choose from for further optimization between
MAS6503 is available in a QFN-16 4x4x0.75 package as well as tested wafer or die in waffle pack. For further information and samples please contact Micro Analog Systems Oy.
