Notes: The VC-708 power supply pin should be filtered, e.g., a 10 uf, 0.1 uf, 0.01 uf and 0.001 uf capacitors. Includes calibration tolerance, operating temperature, supply voltage variations, aging and IR reflow. Figure 1-1 defines these parameters. Duty Cycle is defined as the On Time/Period, see Figure 1-1. Measured using an Agilent E5052. Measured using a LeCroy Wavemaster 8600A, 90K samples, no filtering applied. Measured using a Wavecrest SIA3300C, 90K samples.
