説明
The ZSSC4169D is a high-performance CMOS IC for precise amplification and correction of Wheatstone bridge sensor signals. With digital compensation for offset, drift, and nonlinearity, it delivers excellent accuracy and reliability. Various self-supervision mechanisms allow monitoring for correct functionality during operation. Integrated non-volatile memory (NVM) and digital calibration reduce assembly costs and eliminate external trimming. Focused for automotive use, the ZSSC4169D offers robust protection, excellent EMC, and easy calibration via I²C or OWI interface, making it the most efficient, cost-effective solution for sensor signal processing.
The ZSSC4169D-14 is optimized for SENT output interface and offers measurement of one Wheatstone bridge and additional measurement of one-half bridge branch of the same Wheatstone bridge, and temperature compensation with external P/N junction or internal temperature source. The device also offers bridge input signal amplification up to 200, A/D conversion with 14 bits, and sample rates up to 1.3kHz. Operation in functional safety systems up to ASIL C is supported.
