AC 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.
Settling times, slew rates, and gain bandwidth are based on the analog CT PSoC block.
Power = high and Opamp bias = high is not allowed at 3.3 V.
