are for design guidance only.
The Operational Amplifier is a component of both the Analog Continuous Time PSoC blocks and the Analog Switched Capacitor
PSoC blocks. The guaranteed specifications are measured in the Analog Continuous Time PSoC block.

The common-mode input voltage range is mea-
sured through an analog output buffer. The
specification includes the limitations imposed
by the characteristics of the analog output
buffer.
