Automotive Sensor Signal
Conditioner with LIN Interface
PRELIMINARY
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.
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
• Selectable separate input channel for an external
temperature sensor
• Output options: PWM (bridge sensor signal)
or LIN interface (bridge and temp. sensor signal)
• Digital sensor calibration via LIN interface
• Sampling rate typically 125Hz
• High voltage protection
• Reverse polarity and short circuit protection
• Operation temperature -40 to +125°C
• Supply voltage 8 to 18V
The ZMD31030 is optimized for automotive environments by it’s
protection circuitry and excellent electromagnetic compatibility.
Benefits
• No external trimming components required
• PC-controlled configuration and calibration
via digital LIN bus interface – simple, low cost
• High accuracy ( 0.1ꢀ ꢁSO ꢂ -25 to 85°Cꢃ
0.25ꢀ ꢁSO ꢂ -40 to 125°C)
• 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
