ZMD31020

www.DataSheet4U.com ZMD31020 Sensor Signal Conditioner Datasheet Features Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity Adjustable to nearly all piezo-resistive bridge sensor types Digital one-shot calibration: quick and precise Selectable temperature compensation reference: internal or external diode Output options: 0...5V analog ratiometric voltage 2 or 12 bit digital I C interface Product traceability by user-defined EEPROM entries Operation temperature range, depending on product version, up to –40...+125° C Supply voltage +4.5...+5.5V Sampling rate ≥100Hz Available in SSOP14 or as die Brief Description ZMD31020 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. ZMD31020 accommodates nearly all piezo-resistive bridge sensor types. 2 The bi-directional digital I C interface can be used for a simple PC-controlled one-shot calibration procedure, in order to program a set of calibration coefficients into an on-chip EEPROM. Thus a specific sensor and a ZMD31020 are mated digitally: fast, precise and without the cost overhead associated with trimming by external devices or laser. ZMD31020 has been designed for industrial and consumer applications and is specifically suited for...
