Power Supply Rejection Ratio (PSRR)
Variations in power supply affect the full-scale transition but
not the converter’s linearity. PSRR is the maximum change in
the full-scale transition point due to a change in power supply
voltage from the nominal value (see Figure 11).
Thermal (or Output Voltage) Hysteresis
Thermal (or output voltage) hysteresis is defined as the absolute
maximum change of reference output voltage after the device is
cycled through temperature from either
T_HYS+ = +25°C to T
MAX
to +25°C
or
T_HYS− = +25°C to T
MIN
to +25°C
It is expressed in ppm using the following equation:
