High Linearity, low pressure sensor die -10mbar FS

The AC3055 series of very low pressure die is an extension of the AC3050 low pressure series, meant specifically for passive compensation sensor modules. Despite a die size that is much smaller than traditional low-pressure die, it provides improved zero-stability, reduced g-sensitivity and reduced sensitivity to humidity. The AC3055 is based on the same structure and sensing element of the AC3050 but optimized for improved linearity in the 10 mBar full-scale range. The improved linearity of upwards of 3X over the AC3050 comes at a small sacrifice in maximum sensitivity of about 85% of the AC3050 die. In addition to these standard pressure ranges, the die is available for higher full-scale ranges on a special order basis. Suitable for a wide range of packages, it is particularly designed for low-pressure differential sensing where the die may be used in an uncompensated package or in a passively compensated design where no correction can be made for linearity errors. The AC3055 finds uses in such applications as medical ventilation and respiration, HVAC, air-flow and a variety of industrial pressure and flow applications.
