3.4.3
AC Operational Amplifier Specifications
The following tables list guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and -40°C ≤ TA ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V 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 3.3V.
