Overall Accuracy (VOA %)
VOA is defined as the total output accuracy Referred-to-Output
(RTO). The output accuracy contains all offset and gain errors, at
a single output voltage. Equation 2 is used to calculate the %
total output accuracy.
where
VOUT Actual = VSENSE x GAIN
Example: Gain = 100, For 100mV VSENSE input we measure
Power Dissipation
It is possible to exceed the +150°C maximum junction
temperatures under certain load and power supply conditions. It
is therefore important to calculate the maximum junction
temperature (TJMAX) for all applications to determine if power
supply voltages, load conditions, or package type need to be
modified to remain in the safe operating area. These parameters
are related using Equation 4:
where:
PDMAXTOTAL is the sum of the maximum power dissipation of
each amplifier in the package (PDMAX)
where:
TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation of 1 amplifier
VCC = Total supply voltage
IqMAX = Maximum quiescent supply current of 1 amplifier
VOUTMAX = Maximum output voltage swing of the application
RL = Load resistance
