  • [FAQ] The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA.

    Other Parts Discussed in Thread: XTR116 The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA. Why is that? How can I lower it?

  • [FAQ] Can I use a 2-wire 4-20mA transmitter with a sensor or microcontroller that uses its own supply?

    Other Parts Discussed in Thread: ISO7340C , ISO7310C 2-wire 4-20mA transmitters are loop powered, and the sensor and its associated circuitry are supplied by the transmitter. Is it possible to use a sensor or microcontroller that uses a separate supply…

  • [FAQ] Why does my 2-wire 4-20mA transmitter output not reach the full 20mA?

    Why does my 2-wire 4-20mA transmitter output not reach the full 20mA? When I change the load resistance or decrease the supply, the output changes. What can I do to fix this?

  • [FAQ] Voltage scaling for almost any application (single ended)

    The technical article “ Three ways to scale an analog input ” only covered options for non-inverting and attenuating voltage scaling. Is there a voltage scaling solution for any single ended input range to a desired output range?

  • [FAQ] Automotive amplifiers: Is the LM2904B-Q1 a cross reference replacement for the LM2904-Q1?

    Part Number: LM2904-Q1 Other Parts Discussed in Thread: LM2904B-Q1 Hello, Can you explain why it would be better to use the newly released LM2904B-Q1 in place of the older LM2904-Q1 version when selecting an amplifier for my automotive system designs…
