    current booster, current amplifier

    can u suggest any current booster IC or current amplifier circuit to convert 1-10mA to 1-200mA.......the signal has i/p voltage of 10

    u can achieve this with transistor using amplification

    Re: current booster, current amplifier

    What power supplies do you have?

    What is the maximum frequency of the signal?

    Does the load for the 200mA need to be grounded?

    Re: current booster, current amplifier

    This is a bit of a mess. The OP has started 3 or 4 threads seemingly on the same topic. I answered one of the others here earlier.

    Apparently he wants to boost the output of an AD620 opamp to drive a current of up to 200mA into a load of 500Ω (or 120mA into 1k, pick your thread).

    Not sure if his thread about boosting the current output of an AD620 to drive a 1:10 transformer is related.

    I was wondering about the same thing.

    Re: current booster, current amplifier

    ya...the load is 500 ohm...and it has to be grounded....max frequency is 2000Hz.. i have a 12V and -12V source......

    Re: current booster, current amplifier

    What is the minimum frequency? Must it work down to DC?

    Re: current booster, current amplifier

    no it need not work for DC
