Electrical Specifications
Recommended operating conditions unless otherwise noted. Refer to Block Diagram on page 2 and Typical
Application schematic on page 3. 9V < V_DD < 16V, R_TD = 51.1kΩ, C_T = 470pF, T_A = -40°C to +105°C, Typical
values are at T_A = +25°C; Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise
specified. Temperature limits established by characterization and are not production tested. (Continued)
