Anyone who follows Sensor Tips knows that I am always interested in signal conditioning ICs for sensors. When this involves a company
that I have not known about, it gets even more interesting. This week’s pleasant surprise comes from Micro Analog Systems Oy from Finland. The MAS6502 is a 16-bit piezoresistive sensor signal interface IC primarily intended for MEMS-based pressure sensor modules. To achieve good noise performance, the IC’s ratiometric A/D converter uses a delta-sigma (ΔΣ) conversion technique.
The circuitry can be used to sense temperature as well as not only pressure using built-in sensor sampling switches and communicates via a standard 2-wire I2C serial bus interface.
