7.3.3 Rail-to-Rail Output

The device uses a class-AB output stage with common-source transistors to achieve rail-to-rail output. For high-impedance loads (> 200 Ω), the output voltage swing is typically 100 mV from the supply rails. With 10-Ω loads, a user can achieve a useful output swing while maintaining high open-loop gain; see Figure 20 (Output Voltage Swing vs Output Current).
