Preliminary Information
16
Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
Typical Figures are at 25
°
C with nominal
±
5V and are for design aid only.
Note 5: Refer to Figure 4 & 5 for set up and component values.
Note 6: TLRR is measured from the time when the LR pin is set to 0V (de-selected), to the time when the loop current is within 10% of
its programmed steady state value.
