Hi all, i need to drive a motor which takes in -20mA to 20mA. I got a module from NI, NI 9269 http://sine.ni.com/nips/cds/view/p/lang/en/nid/207638 Basically, this module only supports max of +/- 10mA, and i can't replace it with others as no other modules from NI suits my requirement of +/- 20mA. Therefore my solution would be have a simple circuit to "step up" the current to drive the motors. The circuit would be attached to the NI module at one end, other end would be connected to the motor. I've googled and search this forum, MOSFET would be an ideal choice. But i'm not quite good in electroics, how can i go about it. Can someone reckon me provide me some MOSFET which i look into? MANY THANKS!!
