DC Operational Amplifier Specifications
The following tables 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, 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 CT PSoC blocks and the analog SC PSoC blocks. The guaranteed
specifications are measured in the analog CT PSoC block.
