I'm after a small amplifier to create an adjustable analog voltage with some drive current for a measuring application. If I use and DAC to drive the input then could one of the output pins be used as a pwm version of this signal. Then I'd have a low loss programmable supply.
Does the SSM2305 performance extend all the way to DC or is there a lower frequency limit? The datasheet charts stop at 20Hz but I did not find a lower frequency limit specification.
