Inductive Sensor Analysis Tim Green, MGTS Precision Op Amp Applications Manager April 25, 2018

Summary A TI recommended circuit to scale customer inductive sensor into a 5V full scale ADC input is provided. TI recommended circuit shows little waveform distortion after scaling original Vin signal. Any re-scaling of TI recommended circuit must check for op amp input common mode compliance and linear output voltage swing range. Customer can model the application ADC and check complete signal chain by referring to: https://training.ti.com/ti-precision-labs-adcs Note: All TINA-TI simulations can be run on the embedded schematics in this presentation by downloading the free TI SPICE simulator, TINA-TI, at: http://www.ti.com/tool/tina-ti
