Output Swing Enhancement

When the feedback pin is connected directly to the output

the output voltage swing is limited by the driver stage and

not by output saturation Output swing can be increased as

shown by taking gain in the output stage as shown in High

Power Voltage Follower with Swing Enhancement below

Whenever gain is taken in the output stage as in swing

enhancement either the output stage or the entire op amp

must be appropriately compensated to account for the addi-

tional loop gain

Output Resistance

The open loop output resistance of the LH0101 is a function

of the load current No load output resistance is approxi-

mately 10X This decreases to under 1X for load currents

exceeding 100 mA
