| General description |
The EM6415 is a high resolution A/D converter in low voltage CMOS technology intended to be used as a programmable link between one to four resistive sensors and a microcontroller.
There is no need of external components for calibration, error curve compensation or offset and gain adjustment, nor external amplifiers and sensor bridge drive circuits.
After exposure to a calibration signal/profile, all conversion parameters and profile coefficients are self calculated and stored in an external EEPROM.
In addition to a programmable dual slope 10/13/14 bit A/D conversion, EM6415 allows individual compensation of not only sensor offset and full scale errors, but also temperature error compensation of the sensor zero point and sensitivity, dynamically during the conversion process. EM6415 also contains a programmable sensor drive current source.
