Typical Operating Characteristics
(A_VDD = D_VDD = +5V, V_{DAC_VDD} = +5.0V, GND = 0, LEDG = 0, V_LEDV = +2.7V to +5.25V, V_REF+ - V_REF- = 2.048V (external refer-
ence), V_EXT = 7V, C_REF+ = C_REF- = 0.1µF, C_NEGV = 0.1µF. Internal clock mode, unless otherwise noted. T_A = +25°C, unless other-
wise noted.)
