Sensors Expo 2006: Signal conditioner IC with on-chip diagnostics
ZMD AG introduced the ZMD31015 signal conditioner integrated circuit with on-chip diagnostics at Sensors Expo 2006 held earlier this month in the Chicago area.
ZMD31015 signal conditioner IC with on-chip diagnostics from ZMD AG can be used with nearly all piezo-resistive bridge sensors. CMOS semiconductor device is the newest member of ZMD’s family of resistive bridge (RBic-Lite) signal conditioner integrated circuits. The device was introduced at the recent Sensors Expo held in Rosemont (Chicago), IL, earlier this month.
ZMD31015 provides accurate amplification and sensor-specific correction of bridge sensor signals. Enhanced real-time diagnostics detect any faulty connections, shorts, and power loss events. Signal conditioning is accomplished using an internal digital signal processor running a correction algorithm based on calibration coefficients stored in an on-chip, non-volatile EEPROM.
Measured and corrected bridge values are provided at the signal pin, which can be configured as an analog voltage output or one-wire serial digital output. The digital one-wire output can also be used for a PC-controlled procedure to program calibration coefficients into the on-chip EEPROM.
Internal diagnostics make the device well suited for automation and industrial applications. A supporting development kit, including development board, SOP8 samples, software, and supporting documentation, is available on the company’s Website.
