DESCRIPTION
The 42142 is a power operational amplifier designed for military and space applications where radiation tolerance is
required. Utilizing multi-chip hybrid construction, the 42142 power operational amplifier combines 10A load current
capability with the convenience of a monolithic operational amplifier. Output current limiting is provided using
external resistors. The 42142 power operational amplifier is supplied in an 8-pin hermetic flat package. This design
has demonstrated it will function with minimal degradation after exposure to 100 krad(Si) total dose. This device is
available as COTS, or screened to MIL-PRF-38534, Table C-IX, Class H or custom screening. Lead options
support both through-hole and surface-mount assembly.

Notes:
1. For VS less than ± 22 V, the input voltage is not to exceed ± VS.
2. Input current must not exceed 25 mA
3. It is recommended that external current limiting resistors (± RCL ≥ 0.068 Ω) be used to ensure
that 10 A is not exceeded. See Figures 1, 2 and 4 for RCL application information.
4. Case Temperature TC = 25°C (see Figure 3).

Figure 4. Application Information
Controlling the short circuit current to the minimum necessary for a given application maximizes
device protection and reliability.
Approximate values for the current limiting resistors can be determined from the equation:
RCL = (0.65/ISC - 0.01) Ω
where ISC is the short circuit current limit in amperes at TC = 25°C.
Current limits for positive and negative load currents can be set independently.
Current limiting resistors carry the full output current, therefore the short circuit current limit should be
used in determining resistor wattage. Lead lengths of the limiting resistors should be minimized and
highly inductive resistor types should be avoided.
Large bypass capacitors (50 µF) are recommended across the power supply terminals if the application
requires large output current transients. Care should be taken to keep the power supply ground currents
from flowing through the signal ground path.
