External Resistor Mismatches
Because of the independent pair of feedback terminals provided
by the EL8170 and EL8173, the CMRR is not degraded by any
resistor mismatches. Hence, unlike a three op amp and
especially a two op amp in-amp, the EL8170 and EL8173 reduce
the cost of external components by allowing the use of 1% or
more tolerance resistors without sacrificing CMRR performance.
The EL8170 and EL8173 CMRR is maintained regardless of the
tolerance of the resistors used.
Gain Error and Accuracy
The EL8173 has a Gain Error, EG, of 0.2% typical. The EL8170 has
an EG of 0.3% typical. The gain error indicated in the “Electrical
Specifications” table on page 2 is the inherent gain error of the
EL8170 and EL8173 and does not include the gain error
contributed by the resistors. There is an additional gain error due
to the tolerance of the resistors used. The resulting non-ideal
transfer function effectively becomes Equation 4:
Where:
ERG = Tolerance of RG
ERF = Tolerance of RF
EG = Gain Error of the EL8170 or EL8173
The term [1 - (ERG + ERF + EG)] is the deviation from the
theoretical gain. Thus, (ERG + ERF + EG) is the total gain error. For
example, if 1% resistors are used for the EL8170, the total gain
error would be as shown in Equation 5:
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 in Equation 6:
where:
PDMAXTOTAL is the sum of the maximum power dissipation of
each amplifier in the package (PDMAX)
PDMAX for each amplifier can be calculated as shown in
Equation 7:
where:
TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation of 1 amplifier
VS = Supply voltage (Magnitude of V+ and V-)
IMAX = Maximum supply current of 1 amplifier
VOUTMAX = Maximum output voltage swing of the application
RL = Load resistance
