DC Operational Amplifier Specifications
The following table lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and -40°C

≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and
are for design guidance only.
The Operational Amplifier is a component of both the Analog Continuous Time PSoC blocks and the Analog Switched Cap PSoC
blocks. The guaranteed specifications are measured in the Analog Continuous Time PSoC block. Typical parameters apply to 5V at
25°C and are for design guidance only.
