DC Operational Amplifier Specifications
Tab le 7 and Table 8 on page 17 list the guaranteed maximum and minimum specifications for the voltage and temperature ranges:
4.75 V to 5.25 V and –40 °C T
A
85 °C, or 3.0 V to 3.6 V and –40 °C T
A
85 °C, respectively. Typical parameters apply to 5 V
and 3.3 V at 25 °C and are for design guidance only.
The Operational Amplifier is a component of both the Analog Continuous Time (CT) PSoC blocks and the Analog Switched Capacitor
(SC) PSoC blocks. The guaranteed specifications are measured in the Analog Continuous Time PSoC block.
