 PA194 Data Sheet

The PA194 is a refined implementation of the PA94 power operational amplifier, capable of providing higher speed at 1700 V/µs and very low noise of ∼5 nV/√Hz @ 10 kHz (typical). It is ideal for applications where high speed analog precision is paramount for system operation. Working with voltages of up to 900 V, the PA194 can provide 100 mA of continuous output current. The amplifier consumes ∼4 mA of quiescent current in an integrated standby mode for increased efficiency. The PA194 is housed in an 8-pin power SIP package with heat tab to require minimal board space and facilitate ‘easy’ heat sinking.
