xMR Sensor Signal Conditioner

The ZSSC5101 is a CMOS integrated circuit for converting sine and cosine signals obtained from magnetoresistive bridge sensors into a ratiometric analog voltage with a user-programmable range of travel and clamping levels. The ZSSC5101 accepts sensor bridge arrangements for both rotational as well as linear movement. Depending on the type of sensor bridge, a full-scale travel range of up to 360 mechanical degrees can be obtained. Programming of the device is performed through the output pin, allowing in-line programming of fully assembled 3-wire sensors. Programming parameters are stored in an EEPROM and can be re-programmed multiple times. The ZSSC5101 is fully automotive-qualified with an ambient temperature range up to 150°C for SSOP-14 or 160°C for die.


  • Ratiometric analog output
  • Up to 4608 analog steps
  • Step size as small as 0.022°
  • Programming through output pin via one-wire interface
  • Offset and amplitude calibration of the bridge input signals
  • Programmable linear transfer characteristic: zero position, angular range, upper and lower clamping levels, rising or falling slope
  • Loss of magnet indication with programmable threshold level
  • Accepts anisotropic, giant, and tunnel magnetoresistive bridge sensors (AMR, GMR and TMR)
  • Programmable 32-bit user ID
  • CRC, error detection, and error correction on EEPROM data
  • Diagnostics: broken-wire detection
  • Automotive-qualified to AEC-Q100, grade 0
