Operational Amplifiers Series
Input/Output Full Swing
High Slew Rate
Low Voltage CMOS Operational Amplifiers
BU7291G, BU7291SG, BU7294xx, BU7294Sxx
General Description
BU7291G/BU7294xx and BU7291SG/BU7294Sxx
are low supply voltage CMOS operational single/quad
Amplifiers. This series is a Input/Output full swing, high
slew rate, low supply current and high speed operation.
Input bias current is very low at 1pA (Typ) .
Especially,BU7291SG and BU7294Sxx, it has wide
temperature range from -40C to +105C.
