AC General Purpose I/O Specifications
Table 24 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and
–40 °C  TA  85 °C, 3.0 V to 3.6 V and –40 °C  TA  85 °C, or 2.4 V to 3.0 V and –40 °C  TA  85 °C, respectively. Typical parameters
apply to 5 V, 3.3 V, or 2.7 V at 25 °C and are for design guidance only.

AC 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  TA  85 °C, 3.0 V to 3.6 V and –40 °C  TA  85 °C, or 2.4 V to 3.0 V and –40 °C  TA  85 °C, respectively. Typical
parameters apply to 5 V, 3.3 V, or 2.7 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.
