DESCRIPTION
The Model 1210 is a temperature compensated, piezoresistive
silicon pressure sensor packaged in a dual-in-line configuration.
It is intended for cost sensitive applications where excellent
performance and long-term stability are required.
Integral temperature compensation is provided over a range
of 0-50°C using laser-trimmed resistors. An additional laser-
trimmed resistor is included to normalize pressure sensitivity
variations by programming the gain of an external differential
amplifier. This provides sensitivity interchangeability of ±1%.
Gage, absolute, and differential pressure ranges from 0-2
PSI to 0-100 PSI are available. Multiple lead and tube
configurations are also available for customizing the package for
specific applications.

Notes
1. For 2 psi, output span is 30-60mV.
2.
Compensation resistors are an integral part of the sensor package; no
additional external resistors are required. Pins 7 and 8 must be kept
open.
Best Fit Straight Line.
Temperature range: 0-50°C in reference to 25°C.
Guarantees input/output ratiometricity.
