DESCRIPTION
This AT855x family includes single (AT8551) and dual (AT8551) general purpose CMOS operational amplifiers that provides ultralow noise, offset and power. The AT8551 use auto-zero techniques to simultaneously provide very low offset voltage (5μV max) and near zero-drift over time and temperature.
This miniature, high precision operational amplifiers offset high input impedance and rail-to-rail input and rail-to-rail output swing. With high gain bandwidth product of 4.5MHz and slew rate of 2.7V/μs.
This op amp operates as low as +2.7V (±1.35) and up to +5.5V (±2.75V). The AT8551 single amplifier is available in 5-lead SOT23, 8-lead MSOP8 and 8-lead SOIC packages, The AT8552 dual amplifier is available in 8-lead SOIC and 8-lead MSOP8 narrow surface mount packages. The AT8551/AT8552 (dual version) are specified for the extended industrial and automotive temperature range (−40°C to 125°C).
