Application Circuits
Signal processing circuitry for analog output sensors, such as NVE’s ABL-Series products, varies
widely in cost, complexity, and capability. Depending on user requirements, a single op amp design
may be sufficient. For low signal level detection, a low noise instrumentation amp may be desirable.
For complete control of all parameters, use of a complete signal processing IC which can tailor gain,
offset calibration, and temperature compensation may be required. Please see NVE’s Engineering and
Application Notes bulletin for further details on the various approaches that are available.
For digital output applications, NVE’s AKL-Series and DD-Series products provide the most cost
effective approach. Both of these products provide two-wire, i.e., current modulated output signals. For
many applications, an open collector or digital voltage output signal is desirable. The following two
circuits convert a two-wire current modulated signal into an open collector or digital voltage output
signal:
