PRODUCTS DIVISION
The 42143 Power Operational Amplifier designed for military and space applications where radiation tolerance is
required. Utilizing multi-chip hybrid construction, the 42143 Power Operational Amplifier combines 2A load current
capability with the convenience of a monolithic operational amplifier. Output current limiting is provided using
external resistors. The 42143 Power Operational Amplifier is supplied in an 8-pin metal flat package.
