Simple Pressure Sensor Amplifier & Over Pressure Switch
The pressure sensor amplifier built using LM358 op-amp and MPXM2051GS pressure sensor from NXP semiconductor. The circuit provides 4V output for full scale pressure input 0-7.5PSI. One op-amp is used as amplifier and 2nd op-amp is used as comparator to provide an output at set...

Amplifier requires no dc bias
john guy @ edn.com writes: Intrinsically capacitive transducers and other high-impedance signal sources usually require ac coupling and a buffer amplifier to condition the signal for further processing. Buffers take many forms, but most of them compromise signal quality through the...

How to use a fully differential amplifier as a level shifter
Loren Siebert @ ti.com discuss about how to interface signals that have a reference voltage that isn't 0V while preserving the DC information. Many signal paths are direct current (DC)-coupled, and this can lead to challenges when different portions of the signal path require...
