The
● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. Test conditions are V
+ = 2.7V to 5.5V, RL = 5k, CL = 5pF unless otherwise
noted. The modulation is turned off (MOD is connected to OUT2) unless otherwise specied. RSET is dened as the resistor connected
from the SET pin to the V+ pin.
