General Description
Key Specifications
BU7241G, BU7242xxx, BU7244xx are CMOS
operational amplifier of the input/output full
swing low voltage operation. Also, BU7241SG,
BU7242Sxxx, BU7244Sxx which expanded the
operating temperature range perform a lineup. It
is most suitable for a sensor amplifier and a
battery-powered equipment to have a low input
bias current, the characteristic of the low supply
current.
