Reference
The LTC2261-14/LTC2260-14/LTC2259-14 have an inter-
nal 1.25V voltage reference. For a 2V input range using
the internal reference, connect SENSE to VDD. For a 1V
input range using the internal reference, connect SENSE
to ground. For a 2V input range with an external reference,
apply a 1.25V reference voltage to SENSE (Figure 9.)
The input range can be adjusted by applying a voltage to
SENSE that is between 0.625V and 1.30V. The input range
will then be 1.6 VSENSE.

Figure 9. Using an External 1.25V Reference
The VREF, REFH and REFL pins should be bypassed as
shown in Figure 8. The 0.1F capacitor between REFH
and REFL should be as close to the pins as possible (not
on the back side of the circuit board).
