Datasheet Operational Amplifiers Series Input/Output Full Swing High Slew Rate Low Voltage CMOS Operational Amplifiers BU7291G, BU7291SG, BU7294xx, BU7294Sxx Key Specifications General Description Low Operating Supply Voltage (single supply): BU7291G/BU7294xx and BU7291SG/BU7294Sxx +2.4V to +5.5V are low supply voltage CMOS operational single/quad High Slew Rate: 3.0V/s Amplifiers. This series is a Input/Output full swing, high Wide Temperature Range: slew rate, low supply current and high speed operation. BU7291G/BU7294xx -40 C to +85 C Input bias current is very low at 1pA (Typ) . BU7291SG/BU7294Sxx -40 C to +105 C Especially,BU7291SG and BU7294Sxx, it has wide Low Input Offset Current: 1pA (Typ) temperature range from -40 C to +105 C. Low Input Bias Current: 1pA (Typ) Features High slew rate Input/Output full swing Package W(Typ) x D(Typ) x H(Max) Large DC voltage gain SSOP5 2.90mm x 2.80mm x 1.25mm Low input bias current SOP14 8.70mm x 6.20mm x 1.71mm SSOP-B14 5.00mm x 6.40mm x 1.35mm Application Battery equipment Consumer electronics Simplified schematic VDD Vbias +IN Class OUT AB control -IN Vbias VSS Figure 1.
