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.
