The Output is DC coupled. 2. The VT-803 power supply pin should be ltered, eg, a 10uF, 0.1uF and 0.01uf capacitor. 3. Not all stabilities are available over all temperature ranges. Measured at mid Vc for parts with frequency tuning. 4. After 2 IR re ows and 24 hours. 5. 100, 200 and 280 ppb temp stability parts, all inclusive with 10 years aging. 6. Output is Enabled if E/D is left open. Outline Drawing Table 2.
