Keywords:MKM14  metering  Analogue Front-End  AFE  pressure sensor 

This application note explains the example of how to use MKM14 device in non-electric metering application. In this case, the MKM14 device is used in simple small pressure sensing application with industry standard current loop output 4-20 mA. The benefit of MKM14 is precise Analog Front-End (AFE) is used for reading the pressure sensor with small span of differential voltage output. The next benefit of MKM14 is good computing power on low-power device. This enables implement compensation technique, which is required for low-cost uncompensated pressure sensor devices (such as MPX53 series), used in this application.
