Fast Automotive Sensor Signal Conditioner
ZSC31150
Datasheet
Brief Description
The ZSC31150 is a CMOS integrated circuit for highly accurate
amplification and sensor-specific correction of bridge sensor
signals. Digital compensation of sensor offset, sensitivity,
temperature drift, and non-linearity is accomplished via an internal
16-bit RISC microcontroller running a correction algorithm, with
calibration coefficients stored in an EEPROM.
The ZSC31150 is adjustable to nearly all bridge sensor types.
Measured values are provided at the analog voltage output or at
the digital ZACwireand I2C interface. The digital interface can
be used for a simple PC-controlled calibration procedure in order
to program a set of calibration coefficients into an on-chip
EEPROM. A specific sensor and a ZSC31150 can be mated
digitally: fast, precise, and without the cost overhead associated
with trimming by external devices or a laser.
Features
Digital compensation of sensor offset, sensitivity,
temperature drift, and non-linearity
Adjustable to nearly all bridge sensor types
Analog gain of up to 420
Output options: ratiometric analog voltage output (5% to 95%
maximum, 12.4-bit resolution) or ZACwire(digital one-wire-
interface)
Temperature compensation: internal or external diode, bridge
resistance, thermistor
Sensor biasing by voltage or constant current
Sample rate: up to 7.8kHz
High voltage protection up to 33V
Supply current: max. 5.5mA
Reverse polarity and short-circuit protection
Wide operation temperature depending on part number: up to
-40°C to +150°C
Traceability by user-defined EEPROM entries
Safety and diagnostic functions
Benefits
No external trimming components required
Only a few external protection devices needed
PC-controlled configuration and single pass calibration via
I2C or ZACwireinterface: simple, cost efficient, quick, and
precise
End-of-line calibration via I2C or ZACwireinterface
