Unused Channels
If the application requires only one channel, the user must
configure any unused channel to prevent it from oscillating.
Unused channels can oscillate if the input and output pins are
floating. This will result in higher-than-expected supply currents
and possible noise injection into the channel being used. The
proper way to prevent oscillation is to short the output to the
inverting input, and ground the positive input (Figure 66).
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 1:
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
VS = Total supply voltage
IqMAX = Maximum quiescent supply current of 1 amplifier
VOUTMAX = Maximum output voltage swing of the application
RL = Load resistance
ISL28108, ISL28208, ISL28408 SPICE Model
the net list for the SPICE model. The model is a simplified version
of the actual device and simulates important AC and DC
parameters. AC parameters incorporated into the model are: 1/f
and flat band noise voltage, Slew Rate, CMRR, Gain and Phase.
The DC parameters are IOS, total supply current and output voltage
swing. The model uses typical parameters given in the “Electrical
Specifications” Table beginning on page 6. The AVOL is adjusted
for 122dB with the dominant pole at 1Hz. The CMRR is set 128dB,
f = 6kHz. The input stage models the actual device to present an
accurate AC representation. The model is configured for ambient
temperature of +25°C.
