30 mA. For single 5 V supply applications, resistors less than
169 Ω are not recommended.
INPUT OVERVOLTAGE PROTECTION
The input voltage should be limited to ±6 V, or damage to the
device can occur. Electrostatic protection diodes placed in the
input stage of the device help protect the amplifier from static
discharge. Diodes are connected between each input as well as
from each input to both supply pins as shown in the simplified
equivalent circuit in Figure 33. If an input voltage exceeds either
supply voltage by more than 0.6 V, or if the differential input
voltage is greater than 0.6 V, these diodes energize causing
overvoltage damage.
The input current should be limited to less than 5 mA to
prevent degradation or destruction of the device by placing an
external resistor in series with the input at risk of being overdriven.
The size of the resistor can be calculated by dividing the maxi-
mum input voltage by 5 mA. For example, if the differential
input voltage could reach 5 V, the external resistor should be
5 V/5 mA = 1 kΩ. In practice, this resistor should be placed in
series with both inputs to balance any offset voltages created by
the input bias current.
OUTPUT PHASE REVERSAL
The OP162/OP262/OP462 are immune to phase reversal as
long as the input voltage is limited to ±6 V. Figure 30 shows the
output of a device with the input voltage driven beyond the
supply voltages. Although the device’s output does not change
phase, large currents due to input overvoltage could result,
damaging the device. In applications where the possibility of an
input voltage exceeding the supply voltage exists, overvoltage
protection should be used, as described in the previous section.
POWER DISSIPATION
The maximum power that can be safely dissipated by the
OP162/OP262/OP462 is limited by the associated rise in
junction temperature. The maximum safe junction temperature
is 150°C; device performance suffers when this limit is
exceeded. If this maximum is only momentarily exceeded,
proper circuit operation will be restored as soon as the die
temperature is reduced. Leaving the device in an “overheated”
condition for an extended period can result in permanent
damage to the device.

Figure 36 and Figure 37 provide a convenient way to determine
if the device is being overheated. The maximum safe power
dissipation can be found graphically, based on the package type
and the ambient temperature around the package. By using the
previous equation, it is a simple matter to see if P
