Description
Inverting Input.
An internal feedback loop drives the output common-mode voltage to be equal to the
voltage applied to the V
OCM
pin, provided the amplifier’s operation remains linear.
Positive Power Supply Voltage.
Positive Side of the Differential Output.
Negative Side of the Differential Output.
Negative Power Supply Voltage.
No Internal Connection.
Noninverting Input.
