The amplifier circuit linked below produces two identical outputs, one each above and below the DC line.
Hover over the right bottom corner and click the icon to enlarge.
What I would like to do is create a greater symmetrical DC offset between the two. Something like 3 volts. IOW the low side of channel A would rest at 1.5V above DC, and the high side of channel B would rest at 1.5V below.
Can anyone tell me how to modify the above circuit to do this, without reducing the input signal level?
Also, the spec for this amp is 10ma output. What would be a good substitute part with a rating of 50ma?
