Need help with transconductance operational amplifier

  1. Mar 1, 2013 #1
    Hi all,

    Does anyone know how do I connect an OTA if I want to use it as a voltage-controlled current source, meaning that it will ouput an AC current when i supplied an AC voltage?
    Any guide I can refer to?

    And how do I adjust the gain or transconductance, gm?

    For example, OPA860 with pinout E,C,B, Iq.

    Hi. You pdf seems to provide a lot of information. What application are you hoping to use this for?

    What is your input voltage range and what output current range do you need?
