3.3V Specifications
The following table lists guaranteed maximum and mini-
mum specifications for the voltage and temperature
ranges, 3.3V +/- 10% and -40°C <= TA <= 85°C. The
Operational Amplifier is a component of both the Analog
Continuous Time PSoC blocks and the Analog Switch
Cap PSoC blocks. The guaranteed specifications are
measured in the Analog Continuous Time PSoC block.
Typical parameters apply to 5V at 25°C and are for
design guidance only. For 5V operation, see Table 104
on page 128.
