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