Description
The RHF484 is a rail-to-rail precision bipolar quad
operational amplifier featuring a low input offset
voltage and a wide supply voltage.
Ceramic Flat-14W
Pin connections (top view)
www.DataSheet.net/
The upper metallic lid is not electrically connected to
any pins, nor to the IC die inside the package
Designed to increase tolerance to radiation, the
RHF484 is housed in a hermetic 14-pin flat
package, making it an ideal product for space
applications and harsh environments.
