C, respectively. Typical parameters apply to 5V and 3.3V at 25
°
C and
are for design guidance only.
The guaranteed specifications are measured through the Analog Continuous Time PSoC blocks. The power levels for AGND refer to
the power of the Analog Continuous Time PSoC block. The power levels for RefHi and RefLo refer to the Analog Reference Control
register. The limits stated for AGND include the offset error of the AGND buffer local to the Analog Continuous Time PSoC block.
Reference control power is high.
