FE A T URES: Ex tremely F ast - 5 0 0 v/µS W ide Supply Range ± 1 5 V to ± 4 5 V V M OS Output, No Secondary Breakdo w n Large G ain-Band w idth Product FE T Input Electrically Isolated C ase 8 0 0m A T ypical Output Current A vailable as SM D # 5 9 6 2-9 0 5 0 0 0 1 H X DES CRIPTIO N: T he M S K 1 4 6 1 is a state of the art high speed FE T input operational amplifier. T he distinguishing characteristic of the M S K 1 4 6 1 is its unique V M O S output stage w hich completely eliminates the safe operating area restrictions associated w ith secondary breakdo w n of bipolar transistor output stage op-amps. Freedom from secondary breakdo w n allo w s the 1 4 6 1 to handle large output currents at any voltage le v el limited only by transistor junction temperature. 1 1 5 dB of open loop gain giv es the 1 4 6 1 high closed loop gain accurac y and the t ypical ± 1 . 0 m V of input offset voltage w ill fit w ell in any error budget. A 5 0 0 V /µS sle w rate and 1 2 0 0 M H z gain band w idth product make the 1 4 6 1 an outstanding high-speed op-amp. A single e x ternal capacitor is used for compensation and output current limiting is user programmable through the selection of t w o e x ternal resistors.

APPLIC A TIO N N O TES HE A T SIN KIN G T o select the correct heat sink for your application, refer to the thermal model and gov erning equation belo w . C URREN T LIMIT T he output current of the M S K 1 4 6 1 is internally limited to approximately ± 7 5 0 m A by t w o 0 . 8Ω internal current limit resistors. A dditional current limit can be achieved through the use of t w o e x ternal current limit resistors. O ne resistor ( + R S C ) limits the positiv e output current and the other (-R S C ) limits the negativ e output current. T he v alue of the current limit resistors can be determined...
