ZSC31150

Fast Automotive Sensor Signal Conditioner

Datasheet

Brief Description

Benefits

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.

No external trimming components required

Only a few external protection devices needed

PC-controlled configuration and single pass calibration via

I²C or ZACwire™ interface: simple, cost efficient, quick, and

precise

End-of-line calibration via I²C or ZACwire™ interface

The ZSC31150 is adjustable to nearly all bridge sensor types.

Measured values are provided at the analog voltage output or at

the digital ZACwire™ and 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.

High accuracy (0.25% FSO at -25 to 85°C; 0.5% FSO

at -40°C to 125°C)

Excellent EMC/ESD robustness and AEC-Q100 qualification
