If so, how close to the V- rail (GND) can the AD8036 output be driven?
On +/-5V, (which is close to ground and 8V), the swing is guaranteed to be +/-3.2 w/ a 150 ohm load.
So that is 1.8V from either rail. So on ground and +8V, we can assume you will get close to 1.8V to 6.2V
swing on the output.
Op amps that are spec'ed for plus/minus supplies can usually be operated on ground and +V, with appropriate
consideration paid to IVR, output swing, adjustments. However, the guaranteed min supply voltage for the AD8036
is +/-3V, so the part needs 6V across it. You could take one part and put it on the bench at room temp with ground and +5V and it may "work", but all of the specs may be degraded and it might die at hot or cold depending on the design.
Best option is to choose another part.
Thank you for the information. If I connect the device to +8V/GND, how close to the rails will the output swing? I most interested in how close to ground it will output with V- connected to ground.
