1. The VM-802 power supply pin should be filtered, eg, a 0.1 and 0.01uf capacitor.
2. Includes calibration tolerance, operating temperature, supply voltage variations, aging and IR reflow.
3. Figure 3 defines the test circuit and Figure 4 defines these parameters.
4. Duty Cycle is defined as the On/Time Period.
5. Measured using an Agilent E5052.
6. Measured using a Wavecrest SIA3300C, 90K samples.
7. Outputs will be Enabled if Enable/Disable is left open.
