High voltage considerations should be taken when design-
ing board layouts for the PA240. The PA240 may require a
derate in supply voltage depending on the spacing used for
board layout. The 15-mil and 14-mil minimum spacing of the 7
TO-220 and 7 DDPAK respectively is adequate to standoff the
350V rating of the PA240. However, a supply voltage derate to
250V is required if the spacing of circuit board artwork is less
than 11 mils. In cases where the PA240 is used to its maximum
voltage rating, the PA240CX is recommended given that the
staggered lead form allows for 100-mil standard spacing.
The metal tabs of both the PA240CC and PA240CX pack-
ages are isolated in excess of full supply voltage.
APPLICATIONS
DESCRIPTION
The PA240 is a high voltage monolithic MOSFET opera-
tional amplifier achieving performance features previously
found only in hybrid designs while increasing reliability. Inputs
are protected from excessive common mode and differential
mode voltages. The safe operating area (SOA) has no second
breakdown limitations. External compensation provides the
user flexibility in choosing optimum gain and bandwidth for
the application.
The PA240 is packaged in two standard package designs.
The surface mount version of the PA240, the PA240CC,
is an industry standard non-hermetic plastic 7-pin DDPAK.
The through hole version of the PA240, the PA240CX, is an
industry standard non-hermetic plastic 7-pin TO-220 package.
The PA240CX is a staggered lead formed option that offers
industry standard 100 mil spacing. This allows for easier PC
board layout. (Please refer to package drawings for outline
dimensions.)
