The ZMD31014 RBiciLite™ is a feature rich CMOS integrated circuit for high accuracy amplification and analog-to-digital conversion of a differential input signal. Perfect for low cost applications, the RBiciLite™ can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal.
Developed for correction of resistive bridge sensors, the ZMD31014 can also provide a corrected temperature output through an internal or external sensor measurement. Digital compensation of signal offset, sensitivity, temperature and non-linearity is accomplished via an internal digital signal processor running a correction algorithm. Calibration coefficients are stored in a highly reliable non-volatile EEPROM.
Measured and corrected bridge values provided at the digital output pins can easily be configured as I2C or SPI. Programming of the ZMD31014 is made simple by the I2C interface and the PC-controlled calibration software provided in the ZMD development kit.
The digital mating is fast and precise, eliminating the overhead normally associated with trimming external components and multi-pass calibration routines. Integrated diagnostics functions and low power stand-bymode make the RBiciLite™ attractive for a variety of battery operated applications, particularly ones involving the use of a microcontroller for networking sensors.
