NOTES:
4. Tlow = 0° for SG3525A, 3527A Thigh = +70°C for SG3525A, 3527A
5. Since long term stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability
from lot to lot.
6. Tested at fosc = 40 kHz (RT = 3.6 kΩ, CT = 0.01
µF,
RD = 0Ω).
