ZSSC5101 Datasheet | Renesas

x MR Sensor Signal Conditioner Brief Description 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 160°C.
