Notes:
a. Refer to PROCESS OPTION FLOWCHART for additional information.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Guaranteed by design, not subject to production test.
e. The voltage reference is trimmed with the feedback (Pin 5) connected to compensation (Pin 4) so that the effect of the error amplifier’s input
offset voltage is eliminated.
f. C OSC includes the PC board’s parasitic capacitance.
TYPICAL CHARACTERISTICS 25 °C unless noted
