Note 1: Unless otherwise stated, these specifications apply for T
85°C and LM3524D is 0°C to 70°C. V
Note 2: For operation at elevated temperatures, devices in the N package must be derated based on a thermal resistance of 86°C/W, junction to ambient. Devices
in the M package must be derated at 125°C/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
calculate 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 C
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.
