ABSTRACT:
Pressure sensor circuit (12) develops an input sensor signal (V01) varying linearly as a function of sensed pressure (P) over a range (P.sub.1) of pressure. An error reduction circuit (14-21, R10-R14) having operational amplifiers (16, 19) and a semiconductor device (21) receives the input sensor signal and provides an output signal (V.sub.OUT). The output signal varies at a first high constant rate during a first portion (P.sub.2) of the pressure range and at a lower constant rate during a second portion (P.sub.3) of the pressure range. A break point (BP) between the first and second pressure range portions occurs when the input sensor signal magnitude exceeds a voltage level (V.sub.T) magnitude. The rate of change of the output signal during the first pressure range portion exceeds the rate of change of the input sensor signal during this same pressure range and thus the percentage of error of the output signal is less during the first pressure range portion than the percentage of error of the input sensor signal. The break point and rates of change of the output signal are substantially temperature independent and each can be independently adjusted.
