Note 1: Unless otherwise stated, these specifications apply for TA = TJ = 25C. Boldface numbers apply over the rated temperature range: LM2524D is 40 to 85C
and LM3524D is 0C to 70C. VIN = 20V and fOSC = 20 kHz.
Note 2: For operation at elevated temperatures, devices in the N package must be derated based on a thermal resistance of 86C/W, junction to ambient. Devices
in the M package must be derated at 125C/W, junction to ambient.
Note 3: Tested limits are guaranteed and 100% tested in production.
Note 4: Design limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage range. These limits are not used to cal-
culate outgoing quality level.
Note 5: Absolute maximum ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions.
Note 6: Pins 1, 4, 7, 8, 11, and 14 are grounded; Pin 2 = 2V. All other inputs and outputs open.
Note 7: The value of a Ct capacitor can vary with frequency. Careful selection of this capacitor must be made for high frequency operation. Polystyrene was used
in this test. NPO ceramic or polypropylene can also be used.
Note 8: OSC amplitude is measured open circuit. Available current is limited to 1 mA so care must be exercised to limit capacitive loading of fast pulses.
