ZSSC3136
Datasheet
Brief Description
The ZSSC3136 is a member of the ZSSC313x
family of CMOS integrated circuits for automotive/
industrial sensor applications. All family members
are well suited for highly accurate amplification and
sensor-specific correction of resistive bridge sensor
signals. An internal 16-bit RISC microcontroller
running a correction algorithm compensates sensor
offset, sensitivity, temperature drift, and non-linearity
of the connected sensor element. The required
calibration coefficients are stored by the one-pass
calibration procedure in an on-chip EEPROM.
The ZSSC3136 is optimized for SIL (Safety Integrity
Level) rated switch applications. The integrated
adjustable digital filter offers the possibility of setting
up fast switching real-time applications as well as
stabilized switching applications in the case of
disturbed or unstable input signals.
In addition to the general features for switch appli-
cations, the ZSSC3136 offers the capability to set up
safety-relevant SIL2 rated switches due to its
extended safety functionalities.
