DESCRIPTION
The PA164 and PA165 are high voltage MOSFET operational amplifiers with a monolithic amplifier core
designed for high density power applications with high output currents or voltages. Both devices are
designed for operation up to 200V, with the PA164 providing 1A and the PA165 4A of continuous current.
Separate supplies for the amplifier core and the output stage optimize the overall power dissipation in the
devices. Both devices offer a wide-range, temperature compensated current limit. An additional over-current
flag allows for a flexible implementation of system protection, with an output disable function adding
another layer of optional protection. External compensation provides the user flexibility in choosing optimum
gain and bandwidth for the application.

1. Valid only for device temperature of 25°C or higher.
2. The supply of a boost voltage is optional and can be replaced by the general supply voltage (+VS, -VS). Please also note
the restriction of the overall supply voltage +VB to -VB.
3. If VS is also used for VB, then the maximum voltage can’t exceed the 205V.
4. The case temperature is 25°C
