Automotive Sensor Signal
Conditioner with LIN Interface
PRELIMINAR Y
Brief Description
ZMD31030 is a CMOS integrated circuit for highly-accurate
amplification and sensor-specific correction of bridge sensor
and temperature sensor signals.
Digital compensation of sensor offset, sensitivity, temperature
drift and non-linearity is accomplished via a 16-bit RISC micro-
controller running a correction algorithm with calibration coeffi-
cients stored in a non-volatile EEPROM.
The ZMD31030 is adjustable to nearly all piezo-resistive bridge
sensors. Measured values are provided at the PWM output or at
the LIN interface.
The digital LIN bus interface can be used for a simple PC-con-
trolled calibration procedure, in order to program a set of cali-
bration coefficients into an on-chip EEPROM. Thus a specific
sensor and a ZMD31030 are mated digitally: fast, precise and
without the cost overhead associated with trimming by external
devices or laser.
The ZMD31030 is optimized for automotive environments by it’s
protection circuitry and excellent electromagnetic compatibility.
• Evaluation kit will be available, containing PCBs,
SSOP20 samples, software, documentation
• Support for industrial mass calibration available
• Quick circuit customization possible for large
production volumes
