ISL6726
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to the Block Diagram on page 4 and the
Typical Application schematics on pages 5 and 6. 8V < V_D < 20V, R_TC = 10.0kΩ, C_T = 470pF, T_A = -40°C to +105°C, Typical values are at T_A = +25°C.
Boldface limits apply over the operating temperature range, -40°C to +105°C. (Continued)
