Datasheet

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 -40

C to +105C.
