Note:
Operational amplifiers
L6460 contains two rail to rail output, high bandwidth internally compensated operational
amplifiers supplied by V
Each operational amplifier can have all pin accessible or, to save pins, can be internally
configured as a buffer. They can also be used as comparators; to do that the user must
disable internal compensation by writing a logic level “1” in the OpXCompMode bit in the
OpAmpXCtrl register.

Figure 26. Configurable 3.3 V operational amplifiers
Op1EnPlusRef and Op2EnPlusRef cannot be used to drive external pin so the user must be
sure not to enable the path between one of these voltage references and the external pin.
Figure 26
are reported the block diagrams of the two operational amplifiers.
