ISL71091SEH20 Datasheet, PDF (7/16 Pages) Intersil Corporation – 2.048V Radiation Hardened Ultra Low Noise

ISL71091SEH20
Total Dose Radiation Characteristics This data is typical mean test data post total dose radiation exposure
at both low dose rate (LDR) of <10mrad(Si)/s to 50krads and at a high dose rate (HDR) of 50 to 300rad(Si)/s to 150krads. This data is intended to show
typical parameter shifts due to low dose rate radiation. These are not limits nor are they guaranteed. LDR data to 150krads will be added when available.
V_IN = 5V, T_A = +25°C, I_OUT = 0, C_IN = 0.1µF, C_L = 1µF and C_COMP = 0.001µF unless otherwise specified.
