ZSSC4161BE2W

ZSSC4161BE2W is a CMOS integrated circuit for highly accurate amplification and sensor-specific correction of differential bridge sensor signals. Featuring a maximum analogue preamplification in the range of 150 to 200, this product is adjustable to nearly all resistive bridges as well as voltage source sensor types; e.g., thermocouples. Digital compensation of offset, sensitivity, temperature drift and nonlinearity is accomplished with a 16-bit RISC MCU. Calibration coefficients and configuration data are stored in the NVM which is reliable in automotive applications. Measured values can be read via a digital SENT or I2C interface. The ZSSC416x and the calibration equipment communicate digitally, so the noise sensitivity is greatly reduced. It is optimized for automotive environments by overvoltage and reverse polarity protection circuitry, excellent electromagnetic compatibility, and multiple diagnostic features.
