This AT8557 general-purpose CMOS operational amplifiers that provides ultralow noise, offset and power. The AT8557 use auto-zero techniques to simultaneously provide very low offset voltage (50μV 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 4.3MHz and slew rate of 2.5V/μs.
This op amp operates as low as +2.7V (±1.35) and up to +5.5V (±2.75V). The AT8557 amplifier is available in 5-lead SOT23, 8-lead MSOP8 and 8-lead SOIC packages. The AT8557 is specified for the extended industrial and automotive temperature range (−40°C to 125°C).
