10.3.4 DC Operational Amplifier Specifications
The following tables 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 are measured at 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 capacitor PSoC
blocks. The guaranteed specifications are measured in the analog continuous time PSoC block.
