This application report details signal conditioning for a pressure sensor circuit that can be used for altitude measurements. The goal is to develop a very small system with an acceptable resolution for low-power and low-cost applications. The resulting circuit described here uses a 3-V supply and a single operational amplifier. It is shown that a smart digital processing system can be designed to correct some of the system errors and create a highly competitive product. This report provides information on how a low-cost pressure and height meter might be designed. In addition, it covers some simple basics of altitude measurements and includes a discussion of a pressure–height translation (application example: hiker watch). This document refers to the application report Signal Acquisition and Conditioning With Low Supply Voltages (TI literature number SLAA018), available at any TI sales office or from the TI internet site (www.ti.com). The application is designed for a pressure range of 9.9 psi to 15.75 psi. This relates to the usual range of air pressure from below sea level up to a height of 3000 m above sea level, and fulfills barometric meter requirements. 2 General Circuit Basics Signal conditioning in today’s applications typically consists of a circuit to connect an analog sensor to a digital acquisition system.

In addition, the ap gives us information around operational amplifier, pressure sensor, sensitivity error, output voltage, offset, the amplifier output, signal conditioning, the output signal, compensation, pressure sensor output, the sensitivity error, and the output voltage.
