The AT8551 use auto-zero techniques to simultaneously provide very low offset voltage (5V 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 4.5MH z and slew rate of 2.7V /s.
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. The AT8551 is specified for the extended industrial and automotive temperature range (40°C to 125°C).
