ELECTRICAL CHARACTERISTICS (continued)
(V_DD = V_CPVDD = +5V, V_SGND = V_PGND = 0, SHDN = V_DD, C1 = C2 = 1µF, R_L = ∞, resistive load referenced to ground, for
MAX13330 gain = -1.5V/V (internally set), for MAX13331 gain = -1.5V/V (R_IN = 30kΩ, R_FB = 45kΩ), T_A = T_J = -40°C to +105°C, unless
otherwise noted. Typical values are at T_A = +25°C, unless otherwise noted.) (Note 2)
