Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

5. Performance guaranteed over the indicated operating temperature range by design and/or characterization, tested at TJ = TA = 25°C. Low

duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

6. The noise spectral density from 0.1 Hz to 10 Hz is measured, then the integral output noise voltage in this range is calculated. Finally the

peak to peak noise is calculated as 5x integral output noise.
