AC Operational Amplifier Specifications

Tab le 19 and Table 20 list the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to

5.25 V and –40 °C  T

 85 °C, or 3.0 V to 3.6 V and –40 °C  T

 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 Continuous Time PSoC block.

Power = high and Opamp bias = high is not supported at 3.3 V.
