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, or 2.4 V to 3.0 V and –40 °C T
A
85 °C, respectively.
Typical parameters are measured at 5 V, 3.3 V, and 2.7 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 are measured at 5 V at
25 °C and are for design guidance only.
