The amplifier linearity is calculated using a best fit method at three operating points. The output currents chosen are 20mA, 40mA, and 60mA. The transfer function for IOUT is defined as follows: IOUT = (IIN * GAIN) +IOS. Laser Amplifier VDD = 5V, TA = +25°C, ENABLE = HI unless otherwise specified.
