AD694 Bandwidth

Hello to everybody!


I'm using the AD694 4-20mA Transmiter and I would like to know its bandwidth. I've read the datasheet and it says that the buffer amplifier has a frequency response of 300 kHz, but I'm not sure if this applies to the whole IC.


I've been testing this IC and so far it works fine up to 10 kHz, beyond that frequency the signal is attenuated and in the end it is distorted.


However, my intention is to transmit an up to 100 kHz signal and I'm not sure if the AD694 is the correct choice. I would apreciate if you could give me any insight about this


Thank you very much.
