Vout2

Vout2 is a label used in electrical schematics and datasheets to denote the second output voltage of a device, circuit, or system that provides more than one output. The exact function of Vout2 depends on the particular component, so Vout2 can be a power supply rail, a signal path, or a reference channel. In multi-output regulators or DC-DC converters, Vout2 is a separate regulated output that shares the same input and ground but has its own regulation loop; it may be independently adjustable and specified with its own tolerance and load regulation.

In digital-to-analog converters and other data converters, Vout2 often refers to the second channel's analog output; it is typically measured relative to the reference ground and scaled by the device's internal gain.

In op-amp or instrumentation circuits, Vout2 can be the inverted or complementary output of a differential pair, or the second stage's output voltage.

Measurement and design notes: Vout2 is usually specified with respect to a common reference (ground) or a precision reference node. The voltage can be positive or negative depending on configuration. When two outputs are present, designers must consider cross-regulation, load sharing, noise coupling, and routing to prevent one output from affecting the other. Typical data sheets will define Vout2's nominal value, tolerance, load resistance, line and load regulation, and thermal behavior.

Overall, Vout2 is a context-dependent term that signals a second, distinct output voltage in systems that provide multiple outputs.
