Evaluation Kit for ZSSC416x
The ZSSC4160KIT Evaluation Kit provides the hardware needed for configuration, calibration and evaluation of the ZSSC4161, ZSSC4162, ZSSC4165 and ZSSC4169 Sensor Signal...
概要
説明
The ZSSC4169 is a member of IDT's ZSSC416x family of CMOS integrated circuits for highly accurate amplification and sensor-specific correction of differential bridge sensor signals. Featuring a maximum pre-amplification in the range of 150 to 200, the ZSSC4169 is adjustable to nearly all resistive bridges as well as voltage source sensor types. Digital compensation of offset, sensitivity, temperature drift, and nonlinearity is accomplished with a 16-bit RISC microcontroller. Calibration coefficients and configuration data are stored in an integrated non-volatile memory (NVM), which is reliable in automotive applications. Measured values can be read via a digital SENT. The SENT interface enables transmission of sensor data via its fast channel as well as supplementary data via its Serial Data Message ("slow") channel using only one output pin. End-of-line calibration is supported via an I²C interface or via a One-Wire Interface (OWI) through the data output pin (DOUT). The ZSSC4169 and the calibration equipment communicate digitally, so the noise sensitivity is greatly reduced. Digital calibration helps keep assembly cost low as no trimming by external devices or lasers is needed. The ZSSC4169 is optimized for automotive environments by overvoltage and reverse polarity protection circuitry, excellent electromagnetic compatibility, and multiple diagnostic features.

ZSSC416x/7x Sensor Signal Conditioners Automotive Overview
Modern vehicles are filled with complex sensor systems to achieve optimal performance and lower emissions. IDT's (acquired by Renesas) ZSSC416x and ZSSC417x family of sensor signal conditioner ICs are ideal for use in the engine and exhaust system. Sensing differential pressure at the mass airflow intake using a single IC attached to two sensors lowers power consumption and improves accuracy compared to traditional sensing systems. Manifold pressure and temperature sensing also benefit from using a dual input IC, with higher accuracy measurements resulting in a more optimal fuel mix.
The IDT ZSSC416x and ZSSC417x family of sensor signal conditioners provide a platform for measurement systems with improved accuracy, reliability, and performance with lower power consumption. The family of devices provides highly accurate amplification with integrated compensation, correction, and calibration, while also sharing a common four-millimeter by four-millimeter QFN package and toolset to reduce development and assembly costs.

Modern vehicles are filled with complex sensor systems to achieve optimal performance and lower emissions. IDT's ZSSC416x and ZSSC417x family of sensor signal conditioner ICs are ideal for use in the engine and exhaust system. Sensing differential pressure at the mass airflow intake using a single IC attached to two sensors lowers power consumption and improves accuracy compared to traditional sensing systems. Manifold pressure and temperature sensing also benefits from the use of a dual input IC, with higher accuracy measurements resulting in a more optimal fuel mix.
High temperature sensing across the turbo-charger benefits from a simpler design and lower cost with both thermocouples connecting to the same IC. At the diesel particulate filter, IDT products enable more accurate measurements of filter saturation, resulting in less fuel waste for filter purging. Selective catalytic reduction adds urea to the exhaust to reduce harmful emissions. Improved measurement accuracy leads to better control of urea dosing, reducing urea overuse and refilling costs for the vehicle owner. By more accurately measuring temperature and pressure in the fuel line, the control unit can provide the best fuel/air mix, lowering emissions and improving engine performance.
Compared to traditional anemometers, the sensors used with IDT sensor signal conditioner products are more durable in the harsh environment of exhaust mass airflow measurements, leading to a more reliable, lower power solution. The IDT ZSSC416x and ZSSC417x family of sensor signal conditioners provide a platform for measurement systems with improved accuracy, reliability, and performance with lower power consumption. The family of devices provides highly accurate amplification with integrated compensation, correction, and calibration, while also sharing a common four-millimeter by four-millimeter QFN package and tool set to reduce development and assembly costs.
