7-pin DDPAK Surface Mount Package (PA340CC)

DESCRIPTION

The PA340 is a high voltage monolithic MOSFET oper-

ational amplifier achieving performance features previ-

ously found only in hybrid designs while increasing re-

liability. Inputs are protected from excessive common

mode and differential mode voltages. The safe operat-

ing area (SOA) has no second breakdown limitations.

External compensation provides the user flexibility in

choosing optimum gain and bandwidth for the applica-

tion.

The surface mount package of the PA340CC is an in-

dustry standard non-hermetic plastic 7-pin DDPAK.
