Digitizing transducer interface output voltage is shown on circuit diagram below. The transducer in this case is the NE5521, an LVDT (Linear Variable Differential Transformer) Signal Conditioner. To ensure that the input to the A/D does not go excessively beyond the supply voltage of the A/D, this device is use the diode at the A/D input. For a better description […]

This photodiode signal conditioning circuit is sensitive to light signal, suitable for interfacing digital serial signal. The biasing of the LM111 noninverting input is matched to the diode’s dark output, so it should be very sensitive.
Read moreLow voltage reference is important to provide offset source or biasing, or just a reference for comparator, and its adjustable feature should suit this circuit for many type of applications. [Source: National Semiconductor Application Note]
