Re: Driving a Lo-Z load with opamps question
You can try "buffering" the output of the opamp with a pair of transistors in class B (or just a single transistor if you'll only sink or only source current).  
A CMOS inverter can also be used as an output buffer for opamps. It won't have as much crossover distortion as a class-B bipolar buffer. If you use a CD4049 you can parallel inverters to have more current capacity.

AMZ You could set up the opamps so that... -- 1/14/2000 7:25 PM
