About the SM5651

Advanced Sensor Ceramic Hybrid Technology (CHT) Series is a temperature compensated, mV output, PCB mounted pressure sensor packaged in a rugged Dual In Line package. The Ceramic Hybrid Technology uses a silicon MEMS pressure sensor bound to a ceramic substrate containing thick film resistors that are uniquely laser trimmed for each sensor. Incorporating a flexible design, the CHT-SM5651 Series is available with short, long or no tubes and can be mounted pins up or pins down to allow OEMs to optimize their board design. The CHT-SM5651 series is powered using a constant current and when configured as in the Application Note, the integrated gain set resistor will ensure 2% field interchangeability. The CHT-SM5651 series superior die performance, coupled with rugged ceramic substrate ensures long term stability with superior temperature performance over a wide operating range.
