The output amplitude can be adjusted over a 10:1 range by one of two methods. Voltage at the VADJ pin can be set to a value between VCC, for maximum amplitude, and VCC-2.4 V for an amplitude ~1/10 the max swing. Voltages between these two values will produce a linear change in output swing. Vout ~ [1.1 - 0.44*(VCC - VADJ)] * (VCC - VEE - 0.8) / 2.5Web
