I have a inductive transduver and I need convert the signal of transducer to a current/voltage signal.
I find this IC: http://www.ti.com/lit/ds/symlink/drv401-ep.pdf
Does anyone know a IC more simple? Because this IC has PWM output for example, that I don´t need.
I need convert the signal of inductive transducer for a signal that I can process.
The DRV401 is intended to work with a very special current sensor so I doubt that you would find it useful.
Can you explain what type of transducer you have? What are you sensing? Do you have information such as a data sheet on the transducer?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Bruce Trump:
Thanks for your answer.
I haven´t technical information about my transducer. Is a inductive transducer, that measure linear distance with a relutance variable. The connection with a transducer are two wire...
In reply to Ricardo Pedro:
It is difficult for us to provide meaningful advice without information on the transducer.
Most reluctance distance sensors have some sort of AC excitation from a second coil of some type. Is this the case? Other reluctance sensors have a permanent magnet that provides excitation but they sense motion of, for example, a toothed wheel.
In any case, a two-terminal inductive sensor must provide an AC voltage output. A simple voltage amplifier using an op amp would would be a good start. If you can provide more detail such as frequency, voltage level, etc, we may be able to offer more advice.
In this case, the transducer doesn´t has AC excitation or other type of excitation. A two-terminal provide the value of a variable coil. I think that is how a potentiometer: with variation of distance, the transducer variable a induction (instead resistance in potentiometer).
Sorry, but we cannot provide any help without information on the transducer.
Thank you for yours answers!
