General Description
BU7461G/BU7462xxx/BU7464F are input ground
sense, output full swing CMOS operational amplifiers.
BU7461SG/BU7462Sxxx/BU7464SF have an expanded
operating temperature range. They have the features of
low operating supply voltage, low supply current and low
input bias current. These are suitable for portable
equipment and sensor amplifiers.
