BU7441G BU7441SG BU7442xxx BU7442Sxxx BU7444F BU7444SF
General Description
BU7441G/BU7442xxx/BU7444F are input ground
sense, output full swing CMOS operational
amplifiers. BU7441SG/BU7442Sxxx/BU7444SF
have an expanded operating temperature range.
They have the features of low operating supply
voltage, low supply current and low input bias
current. They are suitable for portable equipment
and sensor amplifiers.

(Note 19) Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.
