PACKAGE/ORDER I FOR ATIO

Note 1: Absolute Maximum Ratings are those values beyond which

the life of the device may be impaired.

Note 2: Connecting any input terminal to voltages greater than V+ or

less than ground may cause destructive latch-up. It is recommended

that no inputs from sources operating from external supplies be

applied prior to power-up of the LTC1046.

Note 3: ROUT is measured at TJ = 25°C immediately after power-on.

Note 4: fOSC is tested with COSC = 100pF to minimize the effects of test

fixture capacitance loading. The 0pF frequency is correlated to this 100pF

test point, and is intended to simulate the capacitance at pin 7 when the

device is plugged into a test socket and no external capacitor is used.
