DC Operational Amplifier Specifications
13.2.1.1
5V Specifications
The following table lists guaranteed maximum and mini-
mum specifications for the voltage and temperature
ranges, 5V +/- 5% and -40°C <= TA <= 85°C. The Opera-
tional Amplifier is a component of both the Analog Con-
tinuous Time PSoC blocks and the Analog Switch Cap
PSoC blocks. The guaranteed specifications are mea-
sured in the Analog Continuous Time PSoC block. Typi-
cal parameters apply to 5V at 25°C and are for design
guidance only. For 3.3V operation, see Table 105 on
page 129.
