| ADVANCED DATA SHEET 42142 RADIATION TOLERANT POWER OPERATIONAL AMPLIFIER Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: Applications: * * * * * * Design Tested to 100 krad(Si) Total Dose Hermetically Sealed in Metal Package Performance over -55C to +125C Wide Supply Voltage Range High Output Current Short Circuit Protection * * * * * * Satellite/Space systems Military/High Reliability Systems Programmable Power Supplies Solenoid Driver Servo Motor Amplifier Synchro Power Amplifier 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.

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) where ISC is the short circuit current limit in amperes at TC = 25C. 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 F) 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.
