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.
