The PA169 is a dual high voltage monolithic operational amplifier. The PA169 houses two independent 200V, 4A peak operational amplifier (PA167) circuits within a 52-pin QFP package. Each channel consists of a monolithic IC input stage and an accompanying MOSFET push-pull output stage. This architecture favors high density power applications with large output current or voltage swing demands. Both independent channels are designed for operation up to 200V while providing 4A of peak output current. High package pin count allows for separate voltage supply pins for the amplifier IC and the output stage to optimize the overall power dissipation in each channel. Each channel offers a wide-range temperature compensated current limit. An over-current flag as well as an output disable function allow for optional implementation of system protection. Optional external phase compensation provides the user with flexibility in creating optimum gain and bandwidth conditions for their application.
