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 <= T
A
<= 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.

1.
The leakage current includes the Analog Continuous Time PSoC block mux and the analog input mux. The leak-
age related to the General Purpose I/O pins is not included here.
The Input Capacitance includes the Analog Continuous Time PSoC block mux and the analog input mux. The
capacitance of the General Purpose I/O pins is not included here.
The common-mode input voltage range is measured through an analog output buffer. The specification includes
the limitations imposed by the characteristics of the analog output buffer
