Description
The ZSSC4162D 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 and digital calibration reduce assembly costs and eliminate external trimming. Focused for automotive use, the ZSSC4162D 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.
An extension to ZSSC4161D, the ZSSC4162D offers enhanced temperature measurement features, especially NTC measurement and linearization capability.
The ZSSC4162D comes with two different product derivatives:
The ZSSC4162D-01 is optimized for SENT output interface, offers measurement of one Wheatstone bridge, temperature compensation with external P/N junction or internal temperature source, and can measure and linearize an external NTC as an independent signal path. Bridge input signal amplification up to 200, A/D conversion up to 18 bits, and sample rates up to 1.45kHz.
The ZSSC4162D-04 is optimized for SENT output interface, offers measurement of one Wheatstone bridge, temperature compensation with external P/N junction or internal temperature source, and can measure and linearize an external NTC as an independent signal path. Bridge input signal amplification up to 200, A/D conversion up to 18 bits, and sample rates up to 1.45kHz. Operation in functional safety systems up to ASIL B is supported.

ZSSC4160D GUI project file
To purchase and test the kit provided by Renesas, I downloaded and ran the file supported on the homepage, and there is a project file for zssc4160b, but there is no project file for zssc4160d. Can I get the file?
