The PA194 is a refined implementation of the PA94 power operational amplifier, capable of providing higher speed at 2100 V/µs and very low noise of ∼4 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.
