ZMD31050

www.DataSheet4U.com ZMD31050 Advanced Differential Sensor Signal Conditioner Datasheet Features Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity Accommodates nearly all bridge sensor types (signal spans from 1 up to 275mV/V processable) Digital one-shot calibration: quick and precise Selectable compensation temperature T1 source: bridge, thermistor, internal diode or external diode Output options: voltage (0...5V), current (4...20mA), PWM, I2C, SPI, ZACwireTM (one-wireinterface), alarm Adjustable output resolution (up to 15 bits) versus sampling rate (up to 3.9kHz) Selectable bridge excitation: ratiometric voltage, constant voltage or constant current Input channel for separate temperature sensor Sensor connection and common mode check (Sensor aging detection) operation temperature, depending on product version, up to -40...+125° C (-40...+150° C derated) Supply voltage +2.7V...+5.5V Available in SSOP16 or as die PRELIMINARY Brief Description ZMD31050 is a CMOS integrated circuit for highlyaccurate amplification and sensor-specific correction of bridge sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift and non-linearity by a 16-bit RISC micro controller running a correction algorithm with correction coefficients stored in non-volatile EEPROM. The ZMD31050 accommodates virtually any bridge sensor (e.g. piezo-resistive, ceramic-thickfilm or steel membrane base...
