Sensor interface aids acquisition
flexibility
The new SX8722 sensor interface will acquire data from Wheatstone bridges or single ended sensors.
Responding to a wide range of inputs such as a pressure sensor, a GMR, AMR, magnetic, chemical sensor, thermistor or a mix of several of these, the new SX8722 sensor interface from Solid State Supplies will acquire data from Wheatstone bridges or single ended sensors The interface is totally configurable through an I2C compatible interface which may be used to set parameters such as alarms or signal processing

The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
Featuring 16 + 10bit 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 four differential or seven single-ended signal inputs and two differential reference inputs.
The SX8722 has internal RC and 32kHz oscillators, power saving sleep/shutdown modes, four full configuration pre selections including: ZoomingADC, two 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).
