DC Operational Amplifier Specifications
Tab le 15 and Table 16 list 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 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 5 V at
25 °C and are for design guidance only.
