The interface is totally configurable through an I2C compatible interface which may be used to set parameters such as alarms or signal processing.
Featuring 16 + 10 bits differential acquisition, preamplifier programmable gain up to 1000 and sensor offset compensation up to 15 times full scale of input signal, the device can handle 4 differential or 7 single ended signal inputs and 2 differential reference inputs.
The SX8722 has internal RC and 32kHz Oscillators, power saving sleep/shutdown modes, four full configuration pre selections including: ZoomingADC, 2 alarms with on/off thresholds and digital filtering. The I2C EEPROM interface has clock out pin, calibration pin, reset pin, ready/busy pin.
Applications for the interface include pressure sensing (industrial, altimeter, diving computer), chemical sensing (monitoring, security) and magnetic sensing (compass).
