hello,
I want to drive a dc motor (speed and direction) and i use the L272 dual power operational amplifier.Is the input voltage level of this op-amp compatible with any D/A converter?
 
Hey,

You need to be more specific.. You want to control the motor with a D/A converter? This isn't a great way to do this..

I would use an 8-bit PWM modulator with a simple H-bridge, then all you would need is the 8-bits for speed and a single bit for direction.

Controlling anything linear like this is a waste of power and generates a ton of heat usually.. Use PWM
