Electrical Specifications VS ± 5V, VCM = 0, VO = 0V, TA = +25°C, unless otherwise noted. Boldface limits apply over the operating

temperature range, -55°C to +125°C; over a total ionizing dose of 300krad(Si) with exposure at a high dose rate of 50 - 300krad(Si)/s (ISL70419SEH only);

or over a total ionizing dose of 50krad(Si) with exposure at a low dose rate of <10mrad(Si)/s.
