3. Electrical Specifications
3.3.3 DC Operational Amplifier Specifications
The following tables list guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and -40°C ≤ T_A ≤ 85°C, 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ T_A ≤ 85°C, respectively. Typical parameters
apply to 5V, 3.3V, and 2.7V at 25°C and are for design guidance only.
The Operational Amplifier is a component of both the Analog Continuous Time PSoC blocks and the Analog Switched 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.

Package and pin dependent. Temp = 25 ^oC.
The common-mode input voltage range is mea-
sured through an analog output buffer. The
specification includes the limitations imposed
by the characteristics of the analog output
buffer.
Specification is applicable at high power. For all
other bias modes (except high power, high
opamp bias), minimum is 60 dB.
